Examples for tracking and evaluating apps with TruLens. Examples are organized by different frameworks (such as Langchain or Llama-Index), model (including Azure, OSS models and more), vector store, and use case.
The examples in this cookbook are more focused on applying core concepts to external libraries or end to end applications than the quickstarts.

Agents are often useful in the RAG setting to retrieve real-time information to be used for question answering.
This example utilizes the openai functions agent to reliably call and return structured responses from particular tools. Certain OpenAI models have been fine-tuned for this capability to detect when a particular function should be called and respond with the inputs required for that function. Compared to a ReACT framework that generates reasoning and actions in an interleaving manner, this strategy can often be more reliable and consistent.
In either case - as the questions change over time, different agents may be needed to retrieve the most useful context. In this example you will create a langchain agent and use TruLens to identify gaps in tool coverage. By quickly identifying this gap, we can quickly add the missing tools to the application and improve the quality of the answers.

The LangChain EnsembleRetriever takes a list of retrievers as input and ensemble the results of their get_relevant_documents() methods and rerank the results based on the Reciprocal Rank Fusion algorithm. With TruLens, we have the ability to evaluate the context of each component retriever along with the ensemble retriever. This example walks through that process.

In this notebook, we are building a LangChain agent to take in user input and figure out the best tool(s) to use via chain of thought (CoT) reasoning.
Given we have more than one distinct tasks defined in the tools for our agent, one being summarization and another one, which generates multiple choice questions and corresponding answers, being more similar to traditional Natural Language Understanding (NLU), we will use to key evaluations for our agent: Tool Input and Tool Selection. Both will be defined with custom functions.

One of the biggest pain-points developers discuss when trying to build useful LLM applications is latency; these applications often make multiple calls to LLM APIs, each one taking a few seconds. It can be quite a frustrating user experience to stare at a loading spinner for more than a couple seconds. Streaming helps reduce this perceived latency by returning the output of the LLM token by token, instead of all at once.
This notebook demonstrates how to monitor a LangChain streaming app with TruLens.

In this example, we build an agent-based app with Llama Index to answer questions with the help of Yelp. We'll evaluate it using a few different feedback functions (some custom, some out-of-the-box)
The first set of feedback functions complete what the non-hallucination triad. However because we're dealing with agents here, we've added a fourth leg (query translation) to cover the additional interaction between the query planner and the agent. This combination provides a foundation for eliminating hallucination in LLM applications.
Query Translation - The first step. Here we compare the similarity of the original user query to the query sent to the agent. This ensures that we're providing the agent with the correct question.
Context or QS Relevance - Next, we compare the relevance of the context provided by the agent back to the original query. This ensures that we're providing context for the right question.
Groundedness - Third, we ensure that the final answer is supported by the context. This ensures that the LLM is not extending beyond the information provided by the agent.
Question Answer Relevance - Last, we want to make sure that the final answer provided is relevant to the user query. This last step confirms that the answer is not only supported but also useful to the end user.
In this example, we'll add two additional feedback functions.
Ratings usage - evaluate if the summarized context uses ratings as justification. Note: this may not be relevant for all queries.
Ground truth eval - we want to make sure our app responds correctly. We will create a ground truth set for this evaluation.
Last, we'll compare the evaluation of this app against a standalone LLM. May the best bot win?

Before we start the evaluator, note that we've logged all of the records including the sub-questions. However we haven't completed any evals yet.
Start the evaluator to generate the feedback results.
In this notebook, we will level up our evaluation using chain of thought reasoning. Chain of thought reasoning through interemediate steps improves LLM's ability to perform complex reasoning - and this includes evaluations. Even better, this reasoning is useful for us as humans to identify and understand new failure modes such as irrelevant retrieval or hallucination.
Second, in this example we will leverage deferred evaluations. Deferred evaluations can be especially useful for cases such as sub-question queries where the structure of our serialized record can vary. By creating different options for context evaluation, we can use deferred evaluations to try both and use the one that matches the structure of the serialized record. Deferred evaluations can be run later, especially in off-peak times for your app.

Then we'll set up a feedback function and wrap the query engine with TruLens' WithFeedbackFilterNodes. This allows us to pass in any feedback function we'd like to use for filtering, even custom ones!
In this example, we're using LLM-as-judge context relevance, but a small local model could be used here as well.

Hybrid Retrievers are a great way to combine the strengths of different retrievers. Combined with filtering and reranking, this can be especially powerful in retrieving only the most relevant context from multiple methods. TruLens can take us even farther to highlight the strengths of each component retriever along with measuring the success of the hybrid retriever.
Last, we'll show how guardrails are an alternative approach to achieving the same goal: passing only relevant context to the LLM.
This example walks through that process.

TruLens feedback functions can be used as context filters in place of reranking. This is great for cases when you don't want to deal with another model (the reranker) or in cases when the feedback function is better aligned to human scores than a reranker. Notably, this feedback function can be any model of your choice - this is a great use of small, lightweight models that don't add as much latency to your app.
To illustrate this, we'll set up a new query engine with only the hybrid retriever (no reranking).

With our documents in hand, we can create our MultiModalVectorStoreIndex. To do so, we parse our Documents into nodes and then simply pass these nodes to the MultiModalVectorStoreIndex constructor.

A keen reader will notice that we stored the text descriptions within the text field of an ImageDocument. As we did before, to create a MultiModalVectorStoreIndex, we'll need to parse the ImageDocuments as ImageNodes, and thereafter pass the nodes to the constructor.
Note that when ImageNodes that have populated text fields are used to build a MultiModalVectorStoreIndex, we can choose to use this text to build embeddings on that will be used for retrieval. To so, we just specify the class attribute is_image_to_text to True.

The images were taken from ASL-Alphabet Kaggle dataset. Note, that they were modified to simply include a label of the associated letter on the hand gesture image. These altered images are what we use as context to the user queries, and they can be downloaded from our google drive (see below cell, which you can uncomment to download the dataset directly from this notebook).
For text context, we use descriptions of each of the hand gestures sourced from https://www.deafblind.com/asl.html. We have conveniently stored these in a json file called asl_text_descriptions.json which is included in the zip download from our google drive.
As in the text-only case, we need to \"attach\" a generator to our index (that can be used as a retriever) to finally assemble our RAG systems. In the multi-modal case however, our generators are Multi-Modal LLMs (or also often referred to as Large Multi-Modal Models or LMM for short). In this notebook, to draw even more comparisons on varied RAG systems, we will use GPT-4V. We can \"attach\" a generator and get an queryable interface for RAG by invoking the as_query_engine method of our indexes.
Let's take a test drive of one these systems. To pretty display the response, we make use of notebook utility function display_query_and_multimodal_response.

Query planning is a useful tool to leverage the ability of LLMs to structure the user inputs into multiple different queries, either sequentially or in parallel before answering the questions. This method improvers the response by allowing the question to be decomposed into smaller, more answerable questions.
Sub-question queries are one such method. Sub-question queries decompose the user input into multiple different sub-questions. This is great for answering complex questions that require knowledge from different documents.
Relatedly, there are a great deal of configurations for this style of application that must be selected. In this example, we'll iterate through several of these choices and evaluate each with TruLens.

Lets consider some feedback functions. We will define two types: a simple language match that checks whether output of the app is in the same language as the input.

Next we define output flows that include checks using all 4 feedback functions we registered above. We will need to specify to the Feedback action the sources of feedback function arguments. The selectors for those can be specified manually or by way of utility container RailsActionSelect. The data structure from which selectors pick our feedback inputs contains all of the arguments of NeMo GuardRails custom action methods:
Though not required, we can also use a trulens recorder to monitor our app.

Lets try to make the app respond in a different language than the question to try to get the language match flow to abort the output. Note that the verbose flag in the feedback action we setup in the colang above makes it print out the inputs and output of the function.
Lets check to make sure all 3 RAG feedback functions will run and hopefully pass. Note that the \"stop\" in their flow definitions means that if any one of them fails, no subsequent ones will be tested.

[Important] Notice in this example notebook, we are using Assistants API V1 (hence the pinned version of openai below) so that we can evaluate against retrieved source. At some very recent point in time as of April 2024, OpenAI removed the \"quote\" attribute from file citation object in Assistants API V2 due to stability issue of this feature.

Amazon Bedrock is a fully managed service that makes FMs from leading AI startups and Amazon available via an API, so you can choose from a wide range of FMs to find the model that is best suited for your use case.
In this quickstart you will learn how to use AWS Bedrock with all the power of tracking + eval with TruLens.
Note: this example assumes logged in with the AWS CLI. Different authentication methods may change the initial client set up, but the rest should remain the same. To retrieve credentials using AWS sso, you will need to download the aws CLI and run:
aws sso login\naws configure export-credentials\n
The second command will provide you with various keys you need.

SageMaker JumpStart provides a variety of pretrained open source and proprietary models such as Llama-2, Anthropic\u2019s Claude and Cohere Command that can be quickly deployed in the Sagemaker environment. In many cases however, these foundation models are not sufficient on their own for production use cases, needing to be adapted to a particular style or new tasks. One way to surface this need is by evaluating the model against a curated ground truth dataset. Once the need to adapt the foundation model is clear, one could leverage a set of techniques to carry that out. A popular approach is to fine-tune the model on a dataset that is tailored to the use case.
One challenge with this approach is that curated ground truth datasets are expensive to create. In this blog post, we address this challenge by augmenting this workflow with a framework for extensible, automated evaluations. We start off with a baseline foundation model from SageMaker JumpStart and evaluate it with TruLens, an open source library for evaluating & tracking LLM apps. Once we identify the need for adaptation, we can leverage fine-tuning in Sagemaker Jumpstart and confirm improvement with TruLens.
TruLens evaluations make use of an abstraction of feedback functions. These functions can be implemented in several ways, including BERT-style models, appropriately prompted Large Language Models, and more. TruLens\u2019 integration with AWS Bedrock allows you to easily run evaluations using LLMs available from AWS Bedrock. The reliability of Bedrock\u2019s infrastructure is particularly valuable for use in performing evaluations across development and production.
In this demo notebook, we demonstrate how to use the SageMaker Python SDK to deploy pre-trained Llama 2 model as well as fine-tune it for your dataset in domain adaptation or instruction tuning format. We will also use TruLens to identify performance issues with the base model and validate improvement of the fine-tuned model.

You can fine-tune on the dataset with domain adaptation format or instruction tuning format. Please find more details in the section Dataset instruction. In this demo, we will use a subset of Dolly dataset in an instruction tuning format. Dolly dataset contains roughly 15,000 instruction following records for various categories such as question answering, summarization, information extraction etc. It is available under Apache 2.0 license. We will select the summarization examples for fine-tuning.
Training data is formatted in JSON lines (.jsonl) format, where each line is a dictionary representing a single data sample. All training data must be in a single folder, however it can be saved in multiple jsonl files. The training folder can also contain a template.json file describing the input and output formats.
To train your model on a collection of unstructured dataset (text files), please see the section Example fine-tuning with Domain-Adaptation dataset format in the Appendix.

In this quickstart, you'll learn how to use the HHEM evaluator feedback function from TruLens in your application. The Vectra HHEM evaluator, or Hughes Hallucination Evaluation Model, is a tool used to determine if a summary produced by a large language model (LLM) might contain hallucinated information.
Purpose: The Vectra HHEM evaluator analyzes both inputs and assigns a score indicating the probability of response containing hallucinations.
Score : The returned value is a floating point number between zero and one that represents a boolean outcome : either a high likelihood of hallucination if the score is less than 0.5 or a low likelihood of hallucination if the score is more than 0.5
e5 embeddings set the SOTA on BEIR and MTEB benchmarks by using only synthetic data and less than 1k training steps. this method achieves strong performance on highly competitive text embedding benchmarks without using any labeled data. Furthermore, when fine-tuned with a mixture of synthetic and labeled data, this model sets new state-of-the-art results on the BEIR and MTEB benchmarks.Improving Text Embeddings with Large Language Models. It also requires a unique prompting mechanism.

In this quickstart you will learn how to use LiteLLM as a feedback function provider.
LiteLLM is a consistent way to access 100+ LLMs such as those from OpenAI, HuggingFace, Anthropic, and Cohere. Using LiteLLM dramatically expands the model availability for feedback functions. Please be cautious in trusting the results of evaluations from models that have not yet been tested.
Specifically in this example we'll show how to use TogetherAI, but the LiteLLM provider can be used to run feedback functions using any LiteLLM supported model. We'll also use Mistral for the embedding and completion model also accessed via LiteLLM. The token usage and cost metrics for models used by LiteLLM will be also tracked by TruLens.
Note: LiteLLM costs are tracked for models included in this litellm community-maintained list.

Building and evaluating RAG applications with Snowflake Arctic offers developers a unique opportunity to leverage a top-tier, enterprise-focused LLM that is both cost-effective and open-source. Arctic excels in enterprise tasks like SQL generation and coding, providing a robust foundation for developing intelligent applications with significant cost savings. Learn more about Snowflake Arctic
In this example, we will use Arctic Embed (snowflake-arctic-embed-m) as our embedding model via HuggingFace, and Arctic, a 480B hybrid MoE LLM for both generation and as the LLM to power TruLens feedback functions. The Arctic LLM is fully-mananaged by Cortex LLM functions
Note, you'll need to have an active Snowflake account to run Cortex LLM functions from Snowflake's data warehouse.

Alternatively, we can use Cortex's Python API (documentation) directly to have cleaner interface and avoid constructing SQL commands ourselves. The reason we are invoking the SQL function directly via snowflake_session.sql() is that the response from Cortex's Python API is still experimental and not as feature-rich as the one from SQL function as of the time of writing. i.e. inconsistency issues with structured json outputs and missing usage information have been observed, lack of support for advanced chat-style (multi-message), etc. Below is a minimal example of using Python API instead.

The top-level organization of this examples repository is divided into quickstarts, expositions, experimental, and dev. Quickstarts are actively maintained to work with every release. Expositions are verified to work with a set of verified dependencies tagged at the top of the notebook which will be updated at every major release. Experimental examples may break between release. Dev examples are used to develop or test releases.
Quickstarts contain the simple examples for critical workflows to build, evaluate and track your LLM app. These examples are displayed in the TruLens documentation under the \"Getting Started\" section.
This expositional library of TruLens examples is organized by the component of interest. Components include /models, /frameworks and /vector-dbs. Use cases are also included under /use_cases. These examples can be found in TruLens documentation as the TruLens cookbook.

Perhaps if we use metadata filters to create specialized query engines, we can improve the search results and thus, the overall evaluation results.
But it may be clunky to have two separate query engines - then we have to decide which one to use!
Instead, let's use a router query engine to choose the query engine based on the query.

MongoDB Atlas Vector Search is part of the MongoDB platform that enables MongoDB customers to build intelligent applications powered by semantic search over any type of data. Atlas Vector Search allows you to integrate your operational database and vector search in a single, unified, fully managed platform with full vector database capabilities.
You can integrate TruLens with your application built on Atlas Vector Search to leverage observability and measure improvements in your application's search capabilities.
This tutorial will walk you through the process of setting up TruLens with MongoDB Atlas Vector Search and Llama-Index as the orchestrator.
Even better, you'll learn how to use metadata filters to create specialized query engines and leverage a router to choose the most appropriate query engine based on the query.
See MongoDB Atlas/LlamaIndex Quickstart for more details.

We can also see that both the euclidean and dot-product metrics performed at a lower latency than cosine at roughly the same evaluation quality. We can move forward with either. Since Euclidean is already loaded in Pinecone, we'll go with that one.
After doing so, we can view our evaluations for all three LLM apps sitting on top of the different indices. All three apps are struggling with query-statement relevance. In other words, the context retrieved is only somewhat relevant to the original query.
Diagnosis: Hallucination.
Digging deeper into the Query Statement Relevance, we notice one problem in particular with a question about famous dental floss brands. The app responds correctly, but is not backed up by the context retrieved, which does not mention any specific brands.
Using a less powerful model is a common way to reduce hallucination for some applications. We\u2019ll evaluate ada-001 in our next experiment for this purpose.
Changing different components of apps built with frameworks like LangChain is really easy. In this case we just need to call \u2018text-ada-001\u2019 from the langchain LLM store. Adding in easy evaluation with TruLens allows us to quickly iterate through different components to find our optimal app configuration.

with tru_chain_with_sources_recorder as recording: for prompt in prompts: chain_with_sources(prompt)
However this configuration with a less powerful model struggles to return a relevant answer given the context provided. For example, when asked \u201cWhich year was Hawaii\u2019s state song written?\u201d, the app retrieves context that contains the correct answer but fails to respond with that answer, instead simply responding with the name of the song.
Note: The way the top_k works with RetrievalQA is that the documents are still retrieved by our semantic search and but only the top_k are passed to the LLM. Howevever TruLens captures all of the context chunks that are being retrieved. In order to calculate an accurate QS Relevance metric that matches what's being passed to the LLM, we need to only calculate the relevance of the top context chunk retrieved.

Our final application has much improved context_relevance, qa_relevance and low latency!

Large Language Models (LLMs) have a hallucination problem. Retrieval Augmented Generation (RAG) is an emerging paradigm that augments LLMs with a knowledge base \u2013 a source of truth set of docs often stored in a vector database like Pinecone, to mitigate this problem. To build an effective RAG-style LLM application, it is important to experiment with various configuration choices while setting up the vector database and study their impact on performance metrics.

Now that we've build our index we can switch over to LangChain. We need to initialize a LangChain vector store using the same index we just built. For this we will also need a LangChain embedding object, which we initialize like so:

Once we\u2019ve set up our app, we should put together our feedback functions. As a reminder, feedback functions are an extensible method for evaluating LLMs. Here we\u2019ll set up 3 feedback functions: context_relevance, qa_relevance, and groundedness. They\u2019re defined as follows:
QS Relevance: query-statement relevance is the average of relevance (0 to 1) for each context chunk returned by the semantic search.
QA Relevance: question-answer relevance is the relevance (again, 0 to 1) of the final answer to the original question.
Groundedness: groundedness measures how well the generated response is supported by the evidence provided to the model where a score of 1 means each sentence is grounded by a retrieved context chunk.

Wrapper of basic apps.
This will be wrapped by instrumentation.
Warning
Because TruWrapperApp may wrap different types of callables, we cannot patch the signature to anything consistent. Because of this, the dashboard/record for this call will have *args, **kwargs instead of what the app actually uses. We also need to adjust the main_input lookup to get the correct signature. See note there.
This is done so we can be aware when new instances are created and is needed for wrapped methods that dynamically create instances of classes we wish to instrument. As they will not be visible at the time we wrap the app, we need to pay attention to new to make a note of them when they are created and the creator's path. This path will be used to place these new instances in the app json structure.
Instantiates a Basic app that makes little assumptions.
Assumes input text and output text.
Example
def custom_application(prompt: str) -> str:\n return \"a response\"\n\nfrom trulens.apps.basic import TruBasicApp\n# f_lang_match, f_qa_relevance, f_context_relevance are feedback functions\ntru_recorder = TruBasicApp(custom_application,\n app_name=\"Custom Application\",\n app_version=\"1\",\n feedbacks=[f_lang_match, f_qa_relevance, f_context_relevance])\n\n# Basic app works by turning your callable into an app\n# This app is accessible with the `app` attribute in the recorder\nwith tru_recorder as recording:\n tru_recorder.app(question)\n\ntru_record = recording.records[0]\n

Wrap any lazy values in the return value of a method call to invoke handle_done when the value is ready.
This is used to handle library-specific lazy values that are hidden in containers not visible otherwise. Visible lazy values like iterators, generators, awaitables, and async generators are handled elsewhere.
PARAMETER DESCRIPTION rets
The return value of the method call.
TYPE: Any
wrap
A callback to be called when the lazy value is ready. Should return the input value or a wrapped version of it.
TYPE: Callable[[T], T]
on_done
Called when the lazy values is done and is no longer lazy. This as opposed to a lazy value that evaluates to another lazy values. Should return the value or wrapper.
TYPE: Callable[[T], T]
context_vars
The contextvars to be captured by the lazy value. If not given, all contexts are captured.
This is an experimental feature with ongoing work.
Create a copy of the json serialized app with the enclosed app being initialized to its initial state before any records are produced (i.e. blank memory).
Timeout in seconds for waiting for feedback results for each feedback function. Note that this is not the total timeout for this entire blocking call.
TYPE: Optional[float] DEFAULT: None
RETURNS DESCRIPTION List[Record]
A list of records that have been waited on. Note a record will be included even if a feedback computation for it failed or timed out.
This applies to all feedbacks on all records produced by this app. This call will block until finished and if new records are produced while this is running, it will include them.
Try to find retriever components in the given app and return a lens to access the retrieved contexts that would appear in a record were these components to execute.
Call the given async func with the given *args and **kwargs while recording, producing func results.
The record of the computation is available through other means like the database or dashboard. If you need a record of this execution immediately, you can use awith_record or the App as a context manager instead.

Create a dummy record with some of the expected structure without actually invoking the app.
The record is a guess of what an actual record might look like but will be missing information that can only be determined after a call is made.
All args are Record fields except these:
- `record_id` is generated using the default id naming schema.\n- `app_id` is taken from this recorder.\n- `calls` field is constructed based on instrumented methods.\n
This wrapper is the most flexible option for instrumenting an application, and can be used to instrument any custom python class.
Example
Consider a mock question-answering app with a context retriever component coded up as two classes in two python, CustomApp and CustomRetriever:
The core tool for instrumenting these classes is the @instrument decorator. TruLens needs to be aware of two high-level concepts to usefully monitor the app: components and methods used by components. The instrument must decorate each method that the user wishes to track.
The owner classes of any decorated method is then viewed as an app component. In this example, case CustomApp and CustomRetriever are components.
Example:\n ### `example.py`\n\n ```python\n from custom_app import CustomApp\n from trulens.apps.custom import TruCustomApp\n\n custom_app = CustomApp()\n\n # Normal app Usage:\n response = custom_app.respond_to_query(\"What is the capital of Indonesia?\")\n\n # Wrapping app with `TruCustomApp`:\n tru_recorder = TruCustomApp(ca)\n\n # Tracked usage:\n with tru_recorder:\n custom_app.respond_to_query, input=\"What is the capital of Indonesia?\")\n ```\n\n`TruCustomApp` constructor arguments are like in those higher-level\n
apps as well including the feedback functions, metadata, etc.
from trulens.apps.custom import instrument\n\nclass CustomRetriever:\n # NOTE: No restriction on this class either.\n\n @instrument\n def retrieve_chunks(self, data):\n return [\n f\"Relevant chunk: {data.upper()}\", f\"Relevant chunk: {data[::-1]}\"\n ]\n
"},{"location":"reference/trulens/apps/custom/#trulens.apps.custom--instrumenting-3rd-party-classes","title":"Instrumenting 3rd party classes","text":"
In cases you do not have access to a class to make the necessary decorations for tracking, you can instead use one of the static methods of instrument, for example, the alternative for making sure the custom retriever gets instrumented is via:
# custom_app.py`:\n\nfrom trulens.apps.custom import instrument\nfrom some_package.from custom_retriever import CustomRetriever\n\ninstrument.method(CustomRetriever, \"retrieve_chunks\")\n\n# ... rest of the custom class follows ...\n
Uses of huggingface inference APIs are tracked as long as requests are made through the requests class's post method to the URL https://api-inference.huggingface.co .
Tracked (instrumented) components must be accessible through other tracked components. Specifically, an app cannot have a custom class that is not instrumented but that contains an instrumented class. The inner instrumented class will not be found by trulens.
All tracked components are categorized as \"Custom\" (as opposed to Template, LLM, etc.). That is, there is no categorization available for custom components. They will all show up as \"uncategorized\" in the dashboard.
Non json-like contents of components (that themselves are not components) are not recorded or available in dashboard. This can be alleviated to some extent with the app_extra_json argument to TruCustomClass as it allows one to specify in the form of json additional information to store alongside the component hierarchy. Json-like (json bases like string, int, and containers like sequences and dicts are included).

If an instrumented / decorated method's owner object cannot be found when traversing your custom class, you will get a warning. This may be ok in the end but may be indicative of a problem. Specifically, note the \"Tracked\" limitation above. You can also use the app_extra_json argument to App / TruCustomApp to provide a structure to stand in place for (or augment) the data produced by walking over instrumented components to make sure this hierarchy contains the owner of each instrumented method.
The owner-not-found error looks like this:
Function <function CustomRetriever.retrieve_chunks at 0x177935d30> was not found during instrumentation walk. Make sure it is accessible by traversing app <custom_app.CustomApp object at 0x112a005b0> or provide a bound method for it as TruCustomApp constructor argument `methods_to_instrument`.\nFunction <function CustomTemplate.fill at 0x1779474c0> was not found during instrumentation walk. Make sure it is accessible by traversing app <custom_app.CustomApp object at 0x112a005b0> or provide a bound method for it as TruCustomApp constructor argument `methods_to_instrument`.\nFunction <function CustomLLM.generate at 0x1779471f0> was not found during instrumentation walk. Make sure it is accessible by traversing app <custom_app.CustomApp object at 0x112a005b0> or provide a bound method for it as TruCustomApp constructor argument `methods_to_instrument`.\n
Subsequent attempts at with_record/awith_record may result in the \"Empty record\" exception.
Usage tracking not tracking. We presently have limited coverage over which APIs we track and make some assumptions with regards to accessible APIs through lower-level interfaces. Specifically, we only instrument the requests module's post method for the lower level tracking. Please file an issue on github with your use cases so we can work out a more complete solution as needed.
Once a method is tracked, its arguments and returns are available to be used in feedback functions. This is done by using the Select class to select the arguments and returns of the method.
Doing so follows the structure:
For args: Select.RecordCalls.<method_name>.args.<arg_name>
For returns: Select.RecordCalls.<method_name>.rets.<ret_name>
Example: \"Defining feedback functions with instrumented methods\"
```python\nf_context_relevance = (\n Feedback(provider.context_relevance_with_cot_reasons, name = \"Context Relevance\")\n .on(Select.RecordCalls.retrieve_chunks.args.query) # refers to the query arg of CustomApp's retrieve_chunks method\n .on(Select.RecordCalls.retrieve_chunks.rets.collect())\n .aggregate(np.mean)\n )\n```\n
Last, the TruCustomApp recorder can wrap our custom application, and provide logging and evaluation upon its use.
Example: \"Using the TruCustomApp recorder\"
```python\nfrom trulens.apps.custom import TruCustomApp\n\ntru_recorder = TruCustomApp(custom_app,\n app_name=\"Custom Application\",\n app_version=\"base\",\n feedbacks=[f_context_relevance])\n\nwith tru_recorder as recording:\n custom_app.respond_to_query(\"What is the capital of Indonesia?\")\n```\n\nSee [Feedback\nFunctions](https://www.trulens.org/trulens/api/feedback/) for\ninstantiating feedback functions.\n

This module facilitates the ingestion and evaluation of application logs that were generated outside of TruLens. It allows for the creation of a virtual representation of your application, enabling the evaluation of logged data within the TruLens framework.
To begin, construct a virtual application representation. This can be achieved through a simple dictionary or by utilizing the VirtualApp class, which allows for a more structured approach to storing application information relevant for feedback evaluation.
Example: \"Constructing a Virtual Application\"
```python\nvirtual_app = {\n 'llm': {'modelname': 'some llm component model name'},\n 'template': 'information about the template used in the app',\n 'debug': 'optional fields for additional debugging information'\n}\n# Converting the dictionary to a VirtualApp instance\nfrom trulens.core import Select\nfrom trulens.apps.virtual import VirtualApp\n\nvirtual_app = VirtualApp(virtual_app)\nvirtual_app[Select.RecordCalls.llm.maxtokens] = 1024\n```\n
Incorporate components into the virtual app for evaluation by utilizing the Select class. This approach allows for the reuse of setup configurations when defining feedback functions.
Example: \"Incorporating Components into the Virtual App\"
```python\n# Setting up a virtual app with a retriever component\nfrom trulens.core import Select\nretriever_component = Select.RecordCalls.retriever\nvirtual_app[retriever_component] = 'this is the retriever component'\n```\n
With your virtual app configured, it's ready to store logged data. VirtualRecord offers a structured way to build records from your data for ingestion into TruLens, distinguishing itself from direct Record creation by specifying calls through selectors.
Below is an example of adding records for a context retrieval component, emphasizing that only the data intended for tracking or evaluation needs to be provided.
Example: \"Adding Records for a Context Retrieval Component\"
```python\nfrom trulens.apps.virtual import VirtualRecord\n\n# Selector for the context retrieval component's `get_context` call\ncontext_call = retriever_component.get_context\n\n# Creating virtual records\nrec1 = VirtualRecord(\n main_input='Where is Germany?',\n main_output='Germany is in Europe',\n calls={\n context_call: {\n 'args': ['Where is Germany?'],\n 'rets': ['Germany is a country located in Europe.']\n }\n }\n)\nrec2 = VirtualRecord(\n main_input='Where is Germany?',\n main_output='Poland is in Europe',\n calls={\n context_call: {\n 'args': ['Where is Germany?'],\n 'rets': ['Poland is a country located in Europe.']\n }\n }\n)\n\ndata = [rec1, rec2]\n```\n
For existing datasets, such as a dataframe of prompts, contexts, and responses, iterate through the dataframe to create virtual records for each entry.
Example: \"Creating Virtual Records from a DataFrame\"
```python\nimport pandas as pd\n\n# Example dataframe\ndata = {\n 'prompt': ['Where is Germany?', 'What is the capital of France?'],\n 'response': ['Germany is in Europe', 'The capital of France is Paris'],\n 'context': [\n 'Germany is a country located in Europe.',\n 'France is a country in Europe and its capital is Paris.'\n ]\n}\ndf = pd.DataFrame(data)\n\n# Ingesting data from the dataframe into virtual records\ndata_dict = df.to_dict('records')\ndata = []\n\nfor record in data_dict:\n rec = VirtualRecord(\n main_input=record['prompt'],\n main_output=record['response'],\n calls={\n context_call: {\n 'args': [record['prompt']],\n 'rets': [record['context']]\n }\n }\n )\n data.append(rec)\n```\n
After constructing the virtual records, feedback functions can be developed in the same manner as with non-virtual applications, using the newly added context_call selector for reference.
Example: \"Developing Feedback Functions\"
```python\nfrom trulens.providers.openai import OpenAI\nfrom trulens.core.feedback.feedback import Feedback\n\n# Initializing the feedback provider\nopenai = OpenAI()\n\n# Defining the context for feedback using the virtual `get_context` call\ncontext = context_call.rets[:]\n\n# Creating a feedback function for context relevance\nf_context_relevance = Feedback(openai.context_relevance).on_input().on(context)\n```\n
These feedback functions are then integrated into TruVirtual to construct the recorder, which can handle most configurations applicable to non-virtual apps.
Example: \"Integrating Feedback Functions into TruVirtual\"
```python\nfrom trulens.apps.virtual import TruVirtual\n\n# Setting up the virtual recorder\nvirtual_recorder = TruVirtual(\n app_name='a virtual app',\n app_version='base',\n app=virtual_app,\n feedbacks=[f_context_relevance]\n)\n```\n
To process the records and run any feedback functions associated with the recorder, use the add_record method.
Example: \"Logging records and running feedback functions\"
```python\n# Ingesting records into the virtual recorder\nfor record in data:\n virtual_recorder.add_record(record)\n```\n
Metadata about your application can also be included in the VirtualApp for evaluation purposes, offering a flexible way to store additional information about the components of an LLM app.
Example: \"Storing metadata in a VirtualApp\"
```python\n# Example of storing metadata in a VirtualApp\nvirtual_app = {\n 'llm': {'modelname': 'some llm component model name'},\n 'template': 'information about the template used in the app',\n 'debug': 'optional debugging information'\n}\n\nfrom trulens.core import Select\nfrom trulens.apps.virtual import VirtualApp\n\nvirtual_app = VirtualApp(virtual_app)\nvirtual_app[Select.RecordCalls.llm.maxtokens] = 1024\n```\n
This approach is particularly beneficial for evaluating the components of an LLM app.
Example: \"Evaluating components of an LLM application\"
```python\n# Adding a retriever component to the virtual app\nretriever_component = Select.RecordCalls.retriever\nvirtual_app[retriever_component] = 'this is the retriever component'\n```\n

Map of feedbacks to the futures for of their results.
These are only filled for records that were just produced. This will not be filled in when read from database. Also, will not fill in when using FeedbackMode.DEFERRED.
Virtual apps are data only in that they cannot be executed but for whom previously-computed results can be added using add_record. The VirtualRecord class may be useful for creating records for this. Fields used by non-virtual apps can be specified here, notably:
See App and AppDefinition for constructor arguments.
You can store any information you would like by passing in a dictionary to TruVirtual in the app field. This may involve an index of components or versions, or anything else. You can refer to these values for evaluating feedback.
Usage
You can use VirtualApp to create the app structure or a plain dictionary. Using VirtualApp lets you use Selectors to define components:
virtual_app = dict(\n llm=dict(\n modelname=\"some llm component model name\"\n ),\n template=\"information about the template I used in my app\",\n debug=\"all of these fields are completely optional\"\n)\n\nvirtual = TruVirtual(\n app_name=\"my_virtual_app\",\n app_version=\"base\",\n app=virtual_app\n)\n

Wrap any lazy values in the return value of a method call to invoke handle_done when the value is ready.
This is used to handle library-specific lazy values that are hidden in containers not visible otherwise. Visible lazy values like iterators, generators, awaitables, and async generators are handled elsewhere.
PARAMETER DESCRIPTION rets
The return value of the method call.
TYPE: Any
wrap
A callback to be called when the lazy value is ready. Should return the input value or a wrapped version of it.
TYPE: Callable[[T], T]
on_done
Called when the lazy values is done and is no longer lazy. This as opposed to a lazy value that evaluates to another lazy values. Should return the value or wrapper.
TYPE: Callable[[T], T]
context_vars
The contextvars to be captured by the lazy value. If not given, all contexts are captured.
This is an experimental feature with ongoing work.
Create a copy of the json serialized app with the enclosed app being initialized to its initial state before any records are produced (i.e. blank memory).
Timeout in seconds for waiting for feedback results for each feedback function. Note that this is not the total timeout for this entire blocking call.
TYPE: Optional[float] DEFAULT: None
RETURNS DESCRIPTION List[Record]
A list of records that have been waited on. Note a record will be included even if a feedback computation for it failed or timed out.
This applies to all feedbacks on all records produced by this app. This call will block until finished and if new records are produced while this is running, it will include them.
Try to find retriever components in the given app and return a lens to access the retrieved contexts that would appear in a record were these components to execute.
Call the given async func with the given *args and **kwargs while recording, producing func results.
The record of the computation is available through other means like the database or dashboard. If you need a record of this execution immediately, you can use awith_record or the App as a context manager instead.

Create a dummy record with some of the expected structure without actually invoking the app.
The record is a guess of what an actual record might look like but will be missing information that can only be determined after a call is made.
All args are Record fields except these:
- `record_id` is generated using the default id naming schema.\n- `app_id` is taken from this recorder.\n- `calls` field is constructed based on instrumented methods.\n
This is done so we can be aware when new instances are created and is needed for wrapped methods that dynamically create instances of classes we wish to instrument. As they will not be visible at the time we wrap the app, we need to pay attention to new to make a note of them when they are created and the creator's path. This path will be used to place these new instances in the app json structure.
This recorder is designed for LangChain apps, providing a way to instrument, log, and evaluate their behavior.
Example: \"Creating a LangChain RAG application\"
Consider an example LangChain RAG application. For the complete code\nexample, see [LangChain\nQuickstart](https://www.trulens.org/trulens/getting_started/quickstarts/langchain_quickstart/).\n\n```python\nfrom langchain import hub\nfrom langchain.chat_models import ChatOpenAI\nfrom langchain.schema import StrOutputParser\nfrom langchain_core.runnables import RunnablePassthrough\n\nretriever = vectorstore.as_retriever()\n\nprompt = hub.pull(\"rlm/rag-prompt\")\nllm = ChatOpenAI(model_name=\"gpt-3.5-turbo\", temperature=0)\n\nrag_chain = (\n {\"context\": retriever | format_docs, \"question\": RunnablePassthrough()}\n | prompt\n | llm\n | StrOutputParser()\n)\n```\n
Feedback functions can utilize the specific context produced by the application's retriever. This is achieved using the select_context method, which then can be used by a feedback selector, such as on(context).
Example: \"Defining a feedback function\"
```python\nfrom trulens.providers.openai import OpenAI\nfrom trulens.core import Feedback\nimport numpy as np\n\n# Select context to be used in feedback.\nfrom trulens.apps.langchain import TruChain\ncontext = TruChain.select_context(rag_chain)\n\n\n# Use feedback\nf_context_relevance = (\n Feedback(provider.context_relevance_with_context_reasons)\n .on_input()\n .on(context) # Refers to context defined from `select_context`\n .aggregate(np.mean)\n)\n```\n
The application can be wrapped in a TruChain recorder to provide logging and evaluation upon the application's use.
Example: \"Using the TruChain recorder\"
```python\nfrom trulens.apps.langchain import TruChain\n\n# Wrap application\ntru_recorder = TruChain(\n chain,\n app_name=\"ChatApplication\",\n app_version=\"chain_v1\",\n feedbacks=[f_context_relevance]\n)\n\n# Record application runs\nwith tru_recorder as recording:\n chain(\"What is langchain?\")\n```\n

Selector shorthands for NeMo Guardrails apps when used for evaluating feedback in actions.
These should not be used for feedback functions given to TruRails but instead for selectors in the FeedbackActions action invoked from with a rails app.
To use this action, it needs to be registered with your rails app and feedback functions themselves need to be registered with this function. The name under which this action is registered for rails is feedback.
Usage
rails: LLMRails = ... # your app\nlanguage_match: Feedback = Feedback(...) # your feedback function\n\n# First we register some feedback functions with the custom action:\nFeedbackAction.register_feedback_functions(language_match)\n\n# Can also use kwargs expansion from dict like produced by rag_triad:\n# FeedbackAction.register_feedback_functions(**rag_triad(...))\n\n# Then the feedback method needs to be registered with the rails app:\nrails.register_action(FeedbackAction.feedback)\n

This is done so we can be aware when new instances are created and is needed for wrapped methods that dynamically create instances of classes we wish to instrument. As they will not be visible at the time we wrap the app, we need to pay attention to new to make a note of them when they are created and the creator's path. This path will be used to place these new instances in the app json structure.
Computed deterministically from app_name and app_version. Leaving it here for it to be dumped when serializing. Also making it read-only as it should not be changed after creation.
Ideally this would be a ClassVar but since we want to check this without instantiating the subclass of AppDefinition that would define it, we cannot use ClassVar.
Info to store about the app and to display in dashboard.
This can be used even if app itself cannot be serialized. app_extra_json, then, can stand in place for whatever data the user might want to keep track of about the app.
Wrap any lazy values in the return value of a method call to invoke handle_done when the value is ready.

Add a single feedback result or future to the database and return its unique id.
PARAMETER DESCRIPTION feedback_result_or_future

If a Future is given, call will wait for the result before adding it to the database. If kwargs are given and a FeedbackResult is also given, the kwargs will be used to update the FeedbackResult otherwise a new one will be created with kwargs as arguments to its constructor.
Typical usage is to specify a feedback implementation function from a Provider and the mapping of selectors describing how to construct the arguments to the implementation:
Example
from trulens.core import Feedback\nfrom trulens.providers.huggingface import Huggingface\nhugs = Huggingface()\n\n# Create a feedback function from a provider:\nfeedback = Feedback(\n hugs.language_match # the implementation\n).on_input_output() # selectors shorthand\n
Only execute the feedback function if the following selector names something that exists in a record/app.
Can use this to evaluate conditionally on presence of some calls, for example. Feedbacks skipped this way will have a status of FeedbackResultStatus.SKIPPED.
Specifies that one argument feedbacks should be evaluated on the main app output and two argument feedbacks should be evaluates on main input and main output in that order.
Returns a new Feedback object with this specification.
Evaluates feedback functions that were specified to be deferred.
Returns a list of tuples with the DB row containing the Feedback and initial FeedbackResult as well as the Future which will contain the actual result.
PARAMETER DESCRIPTION limit
The maximum number of evals to start.
TYPE: Optional[int] DEFAULT: None
shuffle
Shuffle the order of the feedbacks to evaluate.
TYPE: bool DEFAULT: False
run_location
Only run feedback functions with this run_location.
TYPE: Optional[FeedbackRunLocation] DEFAULT: None
Constants that govern behavior:
TruSession.RETRY_RUNNING_SECONDS: How long to time before restarting a feedback that was started but never failed (or failed without recording that fact).
TruSession.RETRY_FAILED_SECONDS: How long to wait to retry a failed feedback.
Specify the aggregation function in case the selectors for this feedback generate more than one value for implementation argument(s). Can also specify the method of producing combinations of values in such cases.
Returns a new Feedback object with the given aggregation function and/or the given combination mode.
Create a variant of self with the same implementation but the given selectors. Those provided positionally get their implementation argument name guessed and those provided as kwargs get their name from the kwargs key.
Check that the selectors are valid for the given app and record.
PARAMETER DESCRIPTION app
The app that produced the record.
TYPE: Union[AppDefinition, JSON]
record
The record that the feedback will run on. This can be a mostly empty record for checking ahead of producing one. The utility method App.dummy_record is built for this purpose.
TYPE: Record
source_data
Additional data to select from when extracting feedback function arguments.
TYPE: Optional[Dict[str, Any]] DEFAULT: None
warning
Issue a warning instead of raising an error if a selector is invalid. As some parts of a Record cannot be known ahead of producing it, it may be necessary to not raise exception here and only issue a warning.
TYPE: bool DEFAULT: False
RETURNS DESCRIPTION bool
True if the selectors are valid. False if not (if warning is set).
Given the app that produced the given record, extract from record the values that will be sent as arguments to the implementation as specified by self.selectors. Additional data to select from can be provided in source_data. All args are optional. If a Record is specified, its calls are laid out as app (see layout_calls_as_app).
TruLens makes use of Feedback Providers to generate evaluations of large language model applications. These providers act as an access point to different models, most commonly classification models and large language models.
These models are then used to generate feedback on application outputs or intermediate results.
Provider is the base class for all feedback providers. It is an abstract class and should not be instantiated directly. Rather, it should be subclassed and the subclass should implement the methods defined in this class.
There are many feedback providers available in TruLens that grant access to a wide range of proprietary and open-source models.
Providers for classification and other non-LLM models should directly subclass Provider. The feedback functions available for these providers are tied to specific providers, as they rely on provider-specific endpoints to models that are tuned to a particular task.
For example, the Huggingface feedback provider provides access to a number of classification models for specific tasks, such as language detection. These models are than utilized by a feedback function to generate an evaluation score.
Example
from trulens.providers.huggingface import Huggingface\nhuggingface_provider = Huggingface()\nhuggingface_provider.language_match(prompt, response)\n
Providers for LLM models should subclass trulens.feedback.LLMProvider, which itself subclasses Provider. Providers for LLM-generated feedback are more of a plug-and-play variety. This means that the base model of your choice can be combined with feedback-specific prompting to generate feedback.
For example, relevance can be run with any base LLM feedback provider. Once the feedback provider is instantiated with a base model, the relevance function can be called with a prompt and response.
This means that the base model selected is combined with specific prompting for relevance to generate feedback.
Example
from trulens.providers.openai import OpenAI\nprovider = OpenAI(model_engine=\"gpt-3.5-turbo\")\nprovider.relevance(prompt, response)\n

Non-serialized fields here while the serialized ones are defined in AppDefinition.
This class is abstract. Use one of these concrete subclasses as appropriate: - TruLlama for LlamaIndex apps. - TruChain for LangChain apps. - TruRails for NeMo Guardrails apps. - TruVirtual for recording information about invocations of apps without access to those apps. - TruCustomApp for custom apps. These need to be decorated to have appropriate data recorded. - TruBasicApp for apps defined solely by a string-to-string method.

This is done so we can be aware when new instances are created and is needed for wrapped methods that dynamically create instances of classes we wish to instrument. As they will not be visible at the time we wrap the app, we need to pay attention to new to make a note of them when they are created and the creator's path. This path will be used to place these new instances in the app json structure.

Add a single feedback result or future to the database and return its unique id.
PARAMETER DESCRIPTION feedback_result_or_future
If a Future is given, call will wait for the result before adding it to the database. If kwargs are given and a FeedbackResult is also given, the kwargs will be used to update the FeedbackResult otherwise a new one will be created with kwargs as arguments to its constructor.
Create a new dataset, if not existing, and add ground truth data to it. If the dataset with the same name already exists, the ground truth data will be added to it.
Migrate the stored data to the current configuration of the database.
PARAMETER DESCRIPTION prior_prefix
If given, the database is assumed to have been reconfigured from a database with the given prefix. If not given, it may be guessed if there is only one table in the database with the suffix alembic_version.
ORM base class except with __tablename__ defined in terms of a base name and a prefix.
A subclass should set _table_base_name and/or _table_prefix. If it does not set both, make sure to set __abstract__ = True. Current design has subclasses set _table_base_name and then subclasses of that subclass setting _table_prefix as in make_orm_for_prefix.
Note: This is a function to be able to define classes extending different SQLAlchemy declarative bases. Each different such bases has a different set of mappings from classes to table names. If we only had one of these, our code will never be able to have two different sets of mappings at the same time. We need to be able to have multiple mappings for performing things such as database migrations and database copying from one database configuration to another.
Create a database for the given engine. Args: engine: The database engine. kwargs: Additional arguments to pass to the database constructor. Returns: A database instance.
Copy all data from a source database to an EMPTY target database.
Important considerations:
All source data will be appended to the target tables, so it is important that the target database is empty.
Will fail if the databases are not at the latest schema revision. That can be fixed with TruSession(database_url=\"...\", database_prefix=\"...\").migrate_database()
Might fail if the target database enforces relationship constraints, because then the order of inserting data matters.
This process is NOT transactional, so it is highly recommended that the databases are NOT used by anyone while this process runs.

The upgrade methodology is determined by this data structure upgrade_paths = { # from_version: (to_version,migrate_function) \"0.1.2\": (\"0.2.0\", migrate_0_1_2), \"0.2.0\": (\"0.3.0\", migrate_0_2_0) }
add your version to the version list: migration_versions: list = [YOUR VERSION HERE,...,\"0.3.0\", \"0.2.0\", \"0.1.2\"]
To Test
replace your db file with an old version db first and see if the session.migrate_database() works.
Add a DB file for testing new breaking changes (Same as step 1: but with your new version)
Do a sys.path.insert(0,TRULENS_PATH) to run with your version
When upgrading TruLens, it may sometimes be required to migrate the database to incorporate changes in existing database created from the previously installed version. The changes to database schemas is handled by Alembic while some data changes are handled by converters in the data module.

This configures the context with just a URL and not an Engine, though an Engine is acceptable here as well. By skipping the Engine creation we don't even need a DBAPI to be available.
Calls to context.execute() here emit the given string to the script output.
Also note that Endpoints are singletons (one for each unique name argument) hence this global callback will track all requests for the named api even if you try to create multiple endpoints (with the same name).
Track costs of all of the apis we can currently track, over the execution of thunk.
RETURNS DESCRIPTION T

TYPE: T
Thunk[Cost]
Thunk[Cost]: A thunk that returns the total cost of all callbacks that tracked costs. This is a thunk as the costs might change after this method returns in case of Awaitable results.
Typical usage is to specify a feedback implementation function from a Provider and the mapping of selectors describing how to construct the arguments to the implementation:
Example
from trulens.core import Feedback\nfrom trulens.providers.huggingface import Huggingface\nhugs = Huggingface()\n\n# Create a feedback function from a provider:\nfeedback = Feedback(\n hugs.language_match # the implementation\n).on_input_output() # selectors shorthand\n
Only execute the feedback function if the following selector names something that exists in a record/app.
Can use this to evaluate conditionally on presence of some calls, for example. Feedbacks skipped this way will have a status of FeedbackResultStatus.SKIPPED.
Specifies that one argument feedbacks should be evaluated on the main app output and two argument feedbacks should be evaluates on main input and main output in that order.
Returns a new Feedback object with this specification.

TruLens makes use of Feedback Providers to generate evaluations of large language model applications. These providers act as an access point to different models, most commonly classification models and large language models.
These models are then used to generate feedback on application outputs or intermediate results.
Provider is the base class for all feedback providers. It is an abstract class and should not be instantiated directly. Rather, it should be subclassed and the subclass should implement the methods defined in this class.
There are many feedback providers available in TruLens that grant access to a wide range of proprietary and open-source models.
Providers for classification and other non-LLM models should directly subclass Provider. The feedback functions available for these providers are tied to specific providers, as they rely on provider-specific endpoints to models that are tuned to a particular task.
For example, the Huggingface feedback provider provides access to a number of classification models for specific tasks, such as language detection. These models are than utilized by a feedback function to generate an evaluation score.
Example
from trulens.providers.huggingface import Huggingface\nhuggingface_provider = Huggingface()\nhuggingface_provider.language_match(prompt, response)\n
Providers for LLM models should subclass trulens.feedback.LLMProvider, which itself subclasses Provider. Providers for LLM-generated feedback are more of a plug-and-play variety. This means that the base model of your choice can be combined with feedback-specific prompting to generate feedback.
For example, relevance can be run with any base LLM feedback provider. Once the feedback provider is instantiated with a base model, the relevance function can be called with a prompt and response.
This means that the base model selected is combined with specific prompting for relevance to generate feedback.
Example
from trulens.providers.openai import OpenAI\nprovider = OpenAI(model_engine=\"gpt-3.5-turbo\")\nprovider.relevance(prompt, response)\n

Many of the classes defined here extending serial.SerialModel are meant to be serialized into json. Most are extended with non-serialized fields in other files.
AppDefinition.app is the JSON-ized version of a wrapped app while App.app is the actual wrapped app. We can thus inspect the contents of a wrapped app without having to construct it. Additionally, JSONized objects like AppDefinition.app feature information about the encoded object types in the dictionary under the util.py:CLASS_INFO key.
Computed deterministically from app_name and app_version. Leaving it here for it to be dumped when serializing. Also making it read-only as it should not be changed after creation.
Ideally this would be a ClassVar but since we want to check this without instantiating the subclass of AppDefinition that would define it, we cannot use ClassVar.
Info to store about the app and to display in dashboard.
This can be used even if app itself cannot be serialized. app_extra_json, then, can stand in place for whatever data the user might want to keep track of about the app.
This is an experimental feature with ongoing work.
Create a copy of the json serialized app with the enclosed app being initialized to its initial state before any records are produced (i.e. blank memory).
Only execute the feedback function if the following selector names something that exists in a record/app.

Note
This class extends str to allow users to compare its values with their string representations, i.e. in if mode == \"none\": .... Internal uses should use the enum instances.
This might involve multiple feedback function calls. Typically you should not be constructing these objects yourself except for the cases where you'd like to log human feedback.

How to collect arguments for feedback function calls.
Note that this applies only to cases where selectors pick out more than one thing for feedback function arguments. This option is used for the field combinations of FeedbackDefinition and can be specified with Feedback.aggregate.
Match argument values per position in produced values.
Example
If the selector for arg1 generates values 0, 1, 2 and one for arg2 generates values \"a\", \"b\", \"c\", the feedback function will be called 3 times with kwargs:
{'arg1': 0, arg2: \"a\"},
{'arg1': 1, arg2: \"b\"},
{'arg1': 2, arg2: \"c\"}
If the quantities of items in the various generators do not match, the result will have only as many combinations as the generator with the fewest items as per python zip (strict mode is not used).
Note that selectors can use Lens collect() to name a single (list) value instead of multiple values.
Evaluate feedback on all combinations of feedback function arguments.
Example
If the selector for arg1 generates values 0, 1 and the one for arg2 generates values \"a\", \"b\", the feedback function will be called 4 times with kwargs:
{'arg1': 0, arg2: \"a\"},
{'arg1': 0, arg2: \"b\"},
{'arg1': 1, arg2: \"a\"},
{'arg1': 1, arg2: \"b\"}
See itertools.product for more.
Note that selectors can use Lens collect() to name a single (list) value instead of multiple values.
Only execute the feedback function if the following selector names something that exists in a record/app.
Can use this to evaluate conditionally on presence of some calls, for example. Feedbacks skipped this way will have a status of FeedbackResultStatus.SKIPPED.
This is shared across different instances of RecordAppCall if they refer to the same python method call. This may happen if multiple recorders capture the call in which case they will each have a different RecordAppCall but the call_id will be the same.
Map of feedbacks to the futures for of their results.

NOTE: we cannot name a module \"async\" as it is a python keyword.
"},{"location":"reference/trulens/core/utils/asynchro/#trulens.core.utils.asynchro--synchronous-vs-asynchronous","title":"Synchronous vs. Asynchronous","text":"
Some functions in TruLens come with asynchronous versions. Those use \"async def\" instead of \"def\" and typically start with the letter \"a\" in their name with the rest matching their synchronous version.
Due to how python handles such functions and how they are executed, it is relatively difficult to reshare code between the two versions. Asynchronous functions are executed by an async loop (see EventLoop). Python prevents any threads from having more than one running loop meaning one may not be able to create one to run some async code if one has already been created/running in the thread. The method sync here, used to convert an async computation into a sync computation, needs to create a new thread. The impact of this, whether overhead, or record info, is uncertain.
"},{"location":"reference/trulens/core/utils/asynchro/#trulens.core.utils.asynchro--what-should-be-syncasync","title":"What should be Sync/Async?","text":"
Try to have all internals be async but for users we may expose sync versions via the sync method. If internals are async and don't need exposure, don't need to provide a synced version.
Run the given function asynchronously with the given args. If it is not asynchronous, will run in thread. Note: this has to be marked async since in some cases we cannot tell ahead of time that func is asynchronous so we may end up running it to produce a coroutine object which we then need to run asynchronously.
Override module's __getattr__ to issue a deprecation errors when looking up attributes.
This expects deprecated names to be prefixed with DEP_ followed by their original pre-deprecation name.
Example
Before deprecationAfter deprecation
# issue module import warning:\npackage_dep_warn()\n\n# define temporary implementations of to-be-deprecated attributes:\nsomething = ... actual working implementation or alias\n
# define deprecated attribute with None/any value but name with \"DEP_\"\n# prefix:\nDEP_something = None\n\n# issue module deprecation warning and override __getattr__ to issue\n# deprecation errors for the above:\nmodule_getattr_override()\n
Also issues a deprecation warning for the module itself. This will be used in the next deprecation stage for throwing errors after deprecation errors.
Issue a deprecation warning for a backwards-compatibility modules.
This is specifically for the trulens_eval -> trulens module renaming and reorganization. If message is given, that is included first in the deprecation warning.
Class to pretend to be a module or some other imported object.
Will raise an error if accessed in some dynamic way. Accesses that are \"static-ish\" will try not to raise the exception so things like defining subclasses of a missing class should not raise exception. Dynamic uses are things like calls, use in expressions. Looking up an attribute is static-ish so we don't throw the error at that point but instead make more dummies.
Warning
While dummies can be used as types, they return false to all isinstance and issubclass checks. Further, the use of a dummy in subclassing produces unreliable results with some of the debugging information such as original_exception may be inaccassible.
This is to make sure that if something optional gets imported as a dummy and is a class to be instrumented, it will not automatically make the instrumentation class check succeed on all objects.
Helper context manager for doing multiple imports from an optional modules
Example
messages = ImportErrorMessages(\n module_not_found=\"install llama_index first\",\n import_error=\"install llama_index==0.1.0\"\n )\n with OptionalImports(messages=messages):\n import llama_index\n from llama_index import query_engine\n
The above python block will not raise any errors but once anything else about llama_index or query_engine gets accessed, an error is raised with the specified message (unless llama_index is installed of course).
Handle exiting from the WithOptionalImports context block.
We should not get any exceptions here if dummies were produced by the overwritten import but if an import of a module that exists failed becomes some component of that module did not, we will not be able to catch it to produce dummy and have to process the exception here in which case we add our informative message to the exception and re-raise it.
Get the path to a static resource file in the trulens package.
By static here we mean something that exists in the filesystem already and not in some temporary folder. We use the importlib.resources context managers to get this but if the resource is temporary, the result might not exist by the time we return or is not expected to survive long.
Check required and optional package versions. Args: ignore_version_mismatch: If set, will not raise an error if a version mismatch is found in a required package. Regardless of this setting, mismatch in an optional package is a warning. Raises: VersionConflict: If a version mismatch is found in a required package and ignore_version_mismatch is not set.
Format two messages for missing optional package or bad import from an optional package.
Throws an ImportError with the formatted message if throw flag is set. If throw is already an exception, throws that instead after printing the message.
Convert the given object into types that can be serialized in json.
Args:\n obj: the object to jsonify.\n\n dicted: the mapping from addresses of already jsonifed objects (via id)\n to their json.\n\n instrument: instrumentation functions for checking whether to recur into\n components of `obj`.\n\n skip_specials: remove specially keyed structures from the json. These\n have keys that start with \"__tru_\".\n\n redact_keys: redact secrets from the output. Secrets are detremined by\n `keys.py:redact_value` .\n\n include_excluded: include fields that are annotated to be excluded by\n pydantic.\n\n depth: the depth of the serialization of the given object relative to\n the serialization of its container.\n
max_depth: the maximum depth of the serialization of the given object. Objects to be serialized beyond this will be serialized as \"non-serialized object\" as pernoserio`. Note that this may happen for some data layouts like linked lists. This value should be no larger than half the value set by sys.setrecursionlimit.
Returns:\n The jsonified version of the given object. Jsonified means that the the\n object is either a JSON base type, a list, or a dict with the containing\n elements of the same.\n

To check whether appropriate api keys have been set:
from trulens.core.utils.keys import check_keys\n\ncheck_keys(\n \"OPENAI_API_KEY\",\n \"HUGGINGFACE_API_KEY\"\n)\n
Alternatively you can set using check_or_set_keys:
from trulens.core.utils.keys import check_or_set_keys\n\ncheck_or_set_keys(\n OPENAI_API_KEY=\"to fill in\",\n HUGGINGFACE_API_KEY=\"to fill in\"\n)\n
This line checks that you have the requisite api keys set before continuing the notebook. They do not need to be provided, however, right on this line. There are several ways to make sure this check passes:
Explicit -- Explicitly provide key values to check_keys.
Python -- Define variables before this check like this:
OPENAI_API_KEY=\"something\"\n
Environment -- Set them in your environment variable. They should be visible when you execute:
import os\nprint(os.environ)\n
.env -- Set them in a .env file in the same folder as the example notebook or one of its parent folders. An example of a .env file is found in trulens/trulens/env.example .
Endpoint class For some keys, set them as arguments to trulens endpoint class that manages the endpoint. For example, with openai, do this ahead of the check_keys check:
from trulens.providers.openai import OpenAIEndpoint\nopenai_endpoint = OpenAIEndpoint(api_key=\"something\")\n
Provider class For some keys, set them as arguments to trulens feedback collection (\"provider\") class that makes use of the relevant endpoint. For example, with openai, do this ahead of the check_keys check:

In the last two cases, please note that the settings are global. Even if you create multiple OpenAI or OpenAIEndpoint objects, they will share the configuration of keys (and other openai attributes).

Some providers may require additional configuration attributes beyond api key. For example, openai usage via azure require special keys. To set those, you should use the 3rd party class method of configuration. For example with openai:
import openai\n\nopenai.api_type = \"azure\"\nopenai.api_key = \"...\"\nopenai.api_base = \"https://example-endpoint.openai.azure.com\"\nopenai.api_version = \"2023-05-15\" # subject to change\n# See https://learn.microsoft.com/en-us/azure/cognitive-services/openai/how-to/switching-endpoints .\n
Our example notebooks will only check that the api_key is set but will make use of the configured openai object as needed to compute feedback.
Determine whether the given value v should be redacted and redact it if so. If its key k (in a dict/json-like) is given, uses the key name to determine whether redaction is appropriate. If key k is not given, only redacts if v is a string and identical to one of the keys ingested using setup_keys.
Check that all keys named in *args are set as env vars. Will fail with a message on how to set missing key if one is missing. If all are provided somewhere, they will be set in the env var as the canonical location where we should expect them subsequently.
Example
from trulens.core.utils.keys import check_keys\n\ncheck_keys(\n \"OPENAI_API_KEY\",\n \"HUGGINGFACE_API_KEY\"\n)\n
Check various sources of api configuration values like secret keys and set env variables for each of them. We use env variables as the canonical storage of these keys, regardless of how they were specified. Values can also be specified explicitly to this method. Example:
from trulens.core.utils.keys import check_or_set_keys\n\ncheck_or_set_keys(\n OPENAI_API_KEY=\"to fill in\",\n HUGGINGFACE_API_KEY=\"to fill in\"\n)\n
Calls to Pace.mark may block until the pace of its returns is kept to a constraint: the number of returns in the given period of time cannot exceed marks_per_second * seconds_per_period. This means the average number of returns in that period is bounded above exactly by marks_per_second.
Assumes that prior to construction of this Pace instance, the period did not have any marks called. The longer this period is, the bigger burst of marks will be allowed initially and after long periods of no marks.
Return in appropriate pace. Blocks until return can happen in the appropriate pace. Returns time in seconds since last mark returned.

Bases: SerialModel
A python class. Should be enough to deserialize the constructor. Also includes bases so that we can query subtyping relationships without deserializing the class first.
An object that may or may not be loadable from its serialized form. Do not use for base types that don't have a class. Loadable if init_bindings is not None.
A python method. A method belongs to some class in some module and must have a pre-bound self object. The location of the method is encoded in obj alongside self. If obj is Obj with init_bindings, this method should be deserializable.
Try to get the attribute k of the given object. This may evaluate some code if the attribute is a property and may fail. In that case, an dict indicating so is returned.
If get_prop is False, will not return contents of properties (will raise ValueException).
Determine which attributes of the given object should be enumerated for storage and/or display in UI. Returns a dict of those attributes and their values.
For enumerating contents of objects that do not support utility classes like pydantic, we use this method to guess what should be enumerated when serializing/displaying.
If include_props is True, will produce attributes which are properties; otherwise those will be excluded.
This is to be able to use weakref.ref on objects like lists which are otherwise not weakly referenceable. The goal of this class is to generalize weakref.ref to work with any object.
This is used for showing \"already created\" warnings. This is intentionally not the frame itself but a rendering of it to avoid maintaining references to frames and all of the things a frame holds onto.
Class for creating singleton instances except there being one instance max, there is one max per different name argument. If name is never given, reverts to normal singleton behavior.
Determine whether the given function is a coroutine function.
Warning
Inspect checkers for async functions do not work on openai clients, perhaps because they use @typing.overload. Because of that, we detect them by checking __wrapped__ attribute instead. Note that the inspect docs suggest they should be able to handle wrapped functions but perhaps they handle different type of wrapping? See https://docs.python.org/3/library/inspect.html#inspect.iscoroutinefunction . Another place they do not work is the decorator langchain uses to mark deprecated functions.

TODO: Lens class: can we store just the python AST instead of building up our own \"Step\" classes to hold the same data? We are already using AST for parsing.
JSON-encoded data the can be deserialized into a given type T.
This class is meant only for type annotations. Any serialization/deserialization logic is handled by different classes, usually subclasses of pydantic.BaseModel.
A step in a path lens that selects an item or an attribute.
Note
TruLens allows looking up elements within sequences if the subelements have the item or attribute. We issue warning if this is ambiguous (looking up in a sequence of more than 1 element).
path = Lens().record[5]['somekey']\n\nobj = ... # some object that contains a value at `obj.record[5]['somekey]`\n\nvalue_at_path = path.get(obj) # that value\n\nnew_obj = path.set(obj, 42) # updates the value to be 42 instead\n
"},{"location":"reference/trulens/core/utils/serial/#trulens.core.utils.serial.Lens--collect-and-special-attributes","title":"collect and special attributes","text":"
Some attributes hold special meaning for lenses. Attempting to access them will produce a special lens instead of one that looks up that attribute.
Example
path = Lens().record[:]\n\nobj = dict(record=[1, 2, 3])\n\nvalue_at_path = path.get(obj) # generates 3 items: 1, 2, 3 (not a list)\n\npath_collect = path.collect()\n\nvalue_at_path = path_collect.get(obj) # generates a single item, [1, 2, 3] (a list)\n
If obj at path self is None or does not exist, sets it to a list containing only the given val. If it already exists as a sequence, appends val to that sequence as a list. If it is set but not a sequence, error is thrown.
Thread that wraps target with copy of context and stack.
App components that do not use this thread class might not be properly tracked.

To further explain how the function works under the hood, consider the statement:
\"Hi. I'm here to help. The university of Washington is a public research university. UW's connections to major corporations in Seattle contribute to its reputation as a hub for innovation and technology\"
The function will split the statement into its component sentences:
\"Hi.\"
\"I'm here to help.\"
\"The university of Washington is a public research university.\"
\"UW's connections to major corporations in Seattle contribute to its reputation as a hub for innovation and technology\"
Next, trivial statements are removed, leaving only:
\"The university of Washington is a public research university.\"
\"UW's connections to major corporations in Seattle contribute to its reputation as a hub for innovation and technology\"
The LLM will then process the statement, to assess the groundedness of the statement.
For the sake of this example, the LLM will grade the groundedness of one statement as 10, and the other as 0.
Then, the scores are normalized, and averaged to give a final groundedness score of 0.5.

The statement will first be split by a tokenizer into its component sentences.
Then, trivial statements are eliminated so as to not delete the evaluation.
The LLM will process each statement, using chain of thought methodology to emit the reasons.
In the case of abstentions, such as 'I do not know', the LLM will be asked to consider the answerability of the question given the source material.

Tuple[float, str]: A tuple containing a value between 0.0 (no stereotypes assumed) and 1.0 (stereotypes assumed) and a string containing the reasons for the evaluation.
To further explain how the function works under the hood, consider the statement:
\"Hi. I'm here to help. The university of Washington is a public research university. UW's connections to major corporations in Seattle contribute to its reputation as a hub for innovation and technology\"
The function will split the statement into its component sentences:
\"Hi.\"
\"I'm here to help.\"
\"The university of Washington is a public research university.\"
\"UW's connections to major corporations in Seattle contribute to its reputation as a hub for innovation and technology\"
Next, trivial statements are removed, leaving only:
\"The university of Washington is a public research university.\"
\"UW's connections to major corporations in Seattle contribute to its reputation as a hub for innovation and technology\"
The LLM will then process the statement, to assess the groundedness of the statement.
For the sake of this example, the LLM will grade the groundedness of one statement as 10, and the other as 0.
Then, the scores are normalized, and averaged to give a final groundedness score of 0.5.

This evaluates the positive sentiment of either the prompt or response.
Sentiment is currently available to use with OpenAI, HuggingFace or Cohere as the model provider.
The OpenAI sentiment feedback function prompts a Chat Completion model to rate the sentiment from 0 to 10, and then scales the response down to 0-1.
The HuggingFace sentiment feedback function returns a raw score from 0 to 1.
The Cohere sentiment feedback function uses the classification endpoint and a small set of examples stored in feedback_prompts.py to return either a 0 or a 1.
To use this module, you must have the trulens-providers-bedrock package installed.
pip install trulens-providers-bedrock\n
Amazon Bedrock is a fully managed service that makes FMs from leading AI startups and Amazon available via an API, so you can choose from a wide range of FMs to find the model that is best suited for your use case
All feedback functions listed in the base LLMProvider class can be run with AWS Bedrock.

Tuple[float, str]: A tuple containing a value between 0.0 (no stereotypes assumed) and 1.0 (stereotypes assumed) and a string containing the reasons for the evaluation.
To further explain how the function works under the hood, consider the statement:
\"Hi. I'm here to help. The university of Washington is a public research university. UW's connections to major corporations in Seattle contribute to its reputation as a hub for innovation and technology\"
The function will split the statement into its component sentences:
\"Hi.\"
\"I'm here to help.\"
\"The university of Washington is a public research university.\"
\"UW's connections to major corporations in Seattle contribute to its reputation as a hub for innovation and technology\"
Next, trivial statements are removed, leaving only:
\"The university of Washington is a public research university.\"
\"UW's connections to major corporations in Seattle contribute to its reputation as a hub for innovation and technology\"
The LLM will then process the statement, to assess the groundedness of the statement.
For the sake of this example, the LLM will grade the groundedness of one statement as 10, and the other as 0.
Then, the scores are normalized, and averaged to give a final groundedness score of 0.5.

To further explain how the function works under the hood, consider the statement:
\"Hi. I'm here to help. The university of Washington is a public research university. UW's connections to major corporations in Seattle contribute to its reputation as a hub for innovation and technology\"
The function will split the statement into its component sentences:
\"Hi.\"
\"I'm here to help.\"
\"The university of Washington is a public research university.\"
\"UW's connections to major corporations in Seattle contribute to its reputation as a hub for innovation and technology\"
Next, trivial statements are removed, leaving only:
\"The university of Washington is a public research university.\"
\"UW's connections to major corporations in Seattle contribute to its reputation as a hub for innovation and technology\"
The LLM will then process the statement, to assess the groundedness of the statement.
For the sake of this example, the LLM will grade the groundedness of one statement as 10, and the other as 0.
Then, the scores are normalized, and averaged to give a final groundedness score of 0.5.

This class makes use of langchain's cost tracking for openai models. Changes to the involved classes will need to be adapted here. The important classes are:
"},{"location":"reference/trulens/providers/openai/endpoint/#trulens.providers.openai.endpoint--changes-for-openai-10","title":"Changes for openai 1.0","text":"
Previously we instrumented classes openai.* and their methods create and acreate. Now we instrument classes openai.resources.* and their create methods. We also instrument openai.resources.chat.* and their create. To be determined is the instrumentation of the other classes/modules under openai.resources.
openai methods produce structured data instead of dicts now. langchain expects dicts so we convert them to dicts.
This class allows wrapped clients to be serialized into json. Does not serialize API key though. You can access openai.OpenAI under the client attribute. Any attributes not defined by this wrapper are looked up from the wrapped client so you should be able to use this instance as if it were an openai.OpenAI instance.
Also note that Endpoints are singletons (one for each unique name argument) hence this global callback will track all requests for the named api even if you try to create multiple endpoints (with the same name).
Track costs of all of the apis we can currently track, over the execution of thunk.
RETURNS DESCRIPTION T

Tuple[float, dict]: A tuple containing a value between 0.0 (not grounded) and 1.0 (grounded) and a dictionary containing the reasons for the evaluation.
A measure to track if the source material supports each sentence in the statement using an LLM provider.
The statement will first be split by a tokenizer into its component sentences.
Then, trivial statements are eliminated so as to not delete the evaluation.
The LLM will process each statement, using chain of thought methodology to emit the reasons.
In the case of abstentions, such as 'I do not know', the LLM will be asked to consider the answerability of the question given the source material.
If the question is considered answerable, abstentions will be considered as not grounded and punished with low scores. Otherwise, unanswerable abstentions will be considered grounded.
The specific criteria for evaluation. Defaults to None.
TYPE: str DEFAULT: None
use_sent_tokenize
Whether to split the statement into sentences using punkt sentence tokenizer. If False, use an LLM to split the statement. Defaults to False. Note this might incur additional costs and reach context window limits in some cases.
TYPE: bool DEFAULT: True
min_score_val
The minimum score value used by the LLM before normalization. Defaults to 0.
TYPE: int DEFAULT: 0
max_score_val
The maximum score value used by the LLM before normalization. Defaults to 3.
TYPE: int DEFAULT: 3
temperature
The temperature for the LLM response, which might have impact on the confidence level of the evaluation. Defaults to 0.0.
TYPE: float DEFAULT: 0.0
RETURNS DESCRIPTION Tuple[float, dict]
Tuple[float, dict]: A tuple containing a value between 0.0 (not grounded) and 1.0 (grounded) and a dictionary containing the reasons for the evaluation.

It has always been our goal to make it easy to build trustworthy LLM applications. Since we launched last May, the package has grown up before our eyes, morphing from a hacked-together addition to an existing project (trulens-explain) to a thriving, agnostic standard for tracking and evaluating LLM apps. Along the way, we\u2019ve experienced growing pains and discovered inefficiencies in the way TruLens was built. We\u2019ve also heard that the reasons people use TruLens today are diverse, and many of its use cases do not require its full footprint. Today we\u2019re announcing an extensive re-architecture of TruLens that aims to give developers a stable, modular platform for logging and evaluation they can rely on.

Next, we modularized TruLens into a family of different packages, described below. This change is designed to minimize the overhead required for TruLens developers to use the capabilities they need. For example, you can now install instrumentation packages in production without the additional dependencies required to run the dashboard.
trulens-core holds core abstractions for database operations, app instrumentation, guardrails and evaluation.
trulens-dashboard gives you the required capabilities to run and operate the TruLens dashboard.
trulens-apps- prefixed packages give you tools for interacting with LLM apps built with other frameworks, giving you capabilities including tracing, logging and guardrailing. These include trulens-apps-langchain and trulens-apps-llamaindex which hold our popular TruChain and TruLlama wrappers that seamlessly instrument LangChain and Llama-Index apps.
trulens-feedback gives you access to out of the box feedback functions required for running feedback functions. Feedback function implementations must be combined with a selected provider integration.
trulens-providers- prefixed package describes a set of integrations with other libraries for running feedback functions. Today, we offer an extensive set of integrations that allow you to run feedback functions on top of virtually any LLM. These integrations can be installed as standalone packages, and include: trulens-providers-openai, trulens-providers-huggingface, trulens-providers-litellm, trulens-providers-langchain, trulens-providers-bedrock, trulens-providers-cortex.
trulens-connectors- provide ways to log TruLens traces and evaluations to other databases. In addition to connect to any sqlalchemy database with trulens-core, we've added with trulens-connectors-snowflake tailored specifically to connecting to Snowflake. We plan to add more connectors over time.

Today, we\u2019re releasing trulens, trulens-core, trulens-dashboard, trulens-feedback, trulens-providers packages, trulens-connectors packages and trulens-apps packages at v1.0. We will not make breaking changes in the future without bumping the major version.
The base install of trulens will install trulens-core, trulens-feedback and trulens-dashboard making it easy for developers to try TruLens.
Starting 1.0, the trulens_eval package is being deprecated in favor of trulens and several associated required and optional packages.
Until 2024-10-14, backwards compatibility during the warning period is provided by the new content of the trulens_eval package which provides aliases to the in their new locations. See trulens_eval.
Starting 2024-10-15 until 2025-12-01. Usage of trulens_eval will produce errors indicating deprecation.
Beginning 2024-12-01 Installation of the latest version of trulens_eval will be an error itself with a message that trulens_eval is no longer maintained.
Along with this change, we\u2019ve also included a migration guide for moving to TruLens v1.
Please give us feedback on GitHub by creating issues and starting discussions. You can also chime in on slack.

In TruLens, we have long had the Tru() class, a singleton that sets the logging configuration. Many users and new maintainers have found the purpose and usage of Tru() not as clear as it could be.
In v1, we are renaming Tru to TruSession, to represent a session for logging TruLens traces and evaluations. In addition, we have introduced a more deliberate set of database of connectors that can be passed to TruSession().
You can see how to start a TruLens session logging to a postgres database below:
In v1, we\u2019re also introducing new ways to track experiments with app_name and app_version. These new required arguments replace app_id to give you a more dynamic way to track app versions.
In our suggested workflow, app_name represents an objective you\u2019re building your LLM app to solve. All apps with the same app_name should be directly comparable with each other. Then app_version can be used to track each experiment. This should be changed each time you change your application configuration. To more explicitly track the changes to individual configurations and semantic names for versions - you can still use app metadata and tags!
To bring these changes to life, we've also added new filters to the Leaderboard and Evaluations pages. These filters give you the power to focus in on particular apps and versions, or even slice to apps with a specific tag or metadata.

Feedback functions are the backbone of TruLens, and evaluating unique LLM apps may require new evaluations. We'd love your contribution to extend the feedback functions library so others can benefit!
To add a feedback function for an existing model provider, you can add it to an existing provider module. You can read more about the structure of a feedback function in this guide.
New methods can either take a single text (str) as a parameter or two different texts (str), such as prompt and retrieved context. It should return a float, or a dict of multiple floats. Each output value should be a float on the scale of 0 (worst) to 1 (best).

Minimal time/effort-to-value If a user already has an llm app coded in one of the supported libraries, give them some value with the minimal effort beyond that app.
Currently to get going, a user needs to add 4 lines of python:
from trulens.dashboard import run_dashboard # line 1\nfrom trulens.apps.langchain import TruChain # line 2\nwith TruChain(app): # 3\n app.invoke(\"some question\") # doesn't count since they already had this\n\nrun_dashboard() # 4\n
3 of these lines are fixed so only #3 would vary in typical cases. From here they can open the dashboard and inspect the recording of their app's invocation including performance and cost statistics. This means trulens must do quite a bit of haggling under the hood to get that data. This is outlined primarily in the Instrumentation section below.
We collect app components and parameters by walking over its structure and producing a json representation with everything we deem relevant to track. The function jsonify is the root of this process.
Classes inheriting BaseModel come with serialization to/from json in the form of model_dump and model_validate. We do not use the serialization to json part of this capability as a lot of LangChain components are tripped to fail it with a \"will not serialize\" message. However, we use make use of pydantic fields to enumerate components of an object ourselves saving us from having to filter out irrelevant internals that are not declared as fields.
We make use of pydantic's deserialization, however, even for our own internal structures (see schema.py for example).
"},{"location":"trulens/contributing/design/#dataclasses-no-present-users","title":"dataclasses (no present users)","text":"
The built-in dataclasses package has similar functionality to pydantic. We use/serialize them using their field information.

In addition to collecting app parameters, we also collect:
(subset of components) App class information:
This allows us to deserialize some objects. Pydantic models can be deserialized once we know their class and fields, for example.
This information is also used to determine component types without having to deserialize them first.
Most if not all LangChain components use pydantic which imposes some restrictions but also provides some utilities. Classes inheriting BaseModel do not allow defining new attributes but existing attributes including those provided by pydantic itself can be overwritten (like dict, for example). Presently, we override methods with instrumented versions.
intercepts package (see https://github.com/dlshriver/intercepts)
Low level instrumentation of functions but is architecture and platform dependent with no darwin nor arm64 support as of June 07, 2023.
sys.setprofile (see https://docs.python.org/3/library/sys.html#sys.setprofile)
Might incur much overhead and all calls and other event types get intercepted and result in a callback.
langchain/llama_index callbacks. Each of these packages come with some callback system that lets one get various intermediate app results. The drawbacks is the need to handle different callback systems for each system and potentially missing information not exposed by them.
wrapt package (see https://pypi.org/project/wrapt/)
This is only for wrapping functions or classes to resemble their original but does not help us with wrapping existing methods in langchain, for example. We might be able to use it as part of our own wrapping scheme though.
The instrumented versions of functions/methods record the inputs/outputs and some additional data (see RecordAppCallMethod). As more than one instrumented call may take place as part of a app invocation, they are collected and returned together in the calls field of Record.
Calls can be connected to the components containing the called method via the path field of RecordAppCallMethod. This class also holds information about the instrumented method.
"},{"location":"trulens/contributing/design/#call-data-argumentsreturns","title":"Call Data (Arguments/Returns)","text":"
The arguments to a call and its return are converted to json using the same tools as App Data (see above).
The same method call with the same path may be recorded multiple times in a Record if the method makes use of multiple of its versions in the class hierarchy (i.e. an extended class calls its parents for part of its task). In these circumstances, the method field of RecordAppCallMethod will distinguish the different versions of the method.
Thread-safety -- it is tricky to use global data to keep track of instrumented method calls in presence of multiple threads. For this reason we do not use global data and instead hide instrumenting data in the call stack frames of the instrumentation methods. See get_all_local_in_call_stack.
Generators and Awaitables -- If an instrumented call produces a generator or awaitable, we cannot produce the full record right away. We instead create a record with placeholder values for the yet-to-be produce pieces. We then instrument (i.e. replace them in the returned data) those pieces with (TODO generators) or awaitables that will update the record when they get eventually awaited (or generated).
Threads do not inherit call stacks from their creator. This is a problem due to our reliance on info stored on the stack. Therefore we have a limitation:
Limitation: Threads need to be started using the utility class TP or ThreadPoolExecutor also defined in utils/threading.py in order for instrumented methods called in a thread to be tracked. As we rely on call stack for call instrumentation we need to preserve the stack before a thread start which python does not do.
Similar to threads, code run as part of a asyncio.Task does not inherit the stack of the creator. Our current solution instruments asyncio.new_event_loop to make sure all tasks that get created in async track the stack of their creator. This is done in tru_new_event_loop . The function stack_with_tasks is then used to integrate this information with the normal caller stack when needed. This may cause incompatibility issues when other tools use their own event loops or interfere with this instrumentation in other ways. Note that some async functions that seem to not involve Task do use tasks, such as gather.
Limitation: Tasks must be created via our task_factory as per task_factory_with_stack. This includes tasks created by function such as asyncio.gather. This limitation is not expected to be a problem given our instrumentation except if other tools are used that modify async in some ways.
Threading and async limitations. See Threads and Async .
If the same wrapped sub-app is called multiple times within a single call to the root app, the record of this execution will not be exact with regards to the path to the call information. All call paths will address the last subapp (by order in which it is instrumented). For example, in a sequential app containing two of the same app, call records will be addressed to the second of the (same) apps and contain a list describing calls of both the first and second.
TODO(piotrm): This might have been fixed. Check.
Some apps cannot be serialized/jsonized. Sequential app is an example. This is a limitation of LangChain itself.
Instrumentation relies on CPython specifics, making heavy use of the inspect module which is not expected to work with other Python implementations.
langchain/llama_index callbacks. These provide information about component invocations but the drawbacks are need to cover disparate callback systems and possibly missing information not covered.
Our tracking of calls uses instrumentated versions of methods to manage the recording of inputs/outputs. The instrumented methods must distinguish themselves from invocations of apps that are being tracked from those not being tracked, and of those that are tracked, where in the call stack a instrumented method invocation is. To achieve this, we rely on inspecting the python call stack for specific frames:
Prior frame -- Each instrumented call searches for the topmost instrumented call (except itself) in the stack to check its immediate caller (by immediate we mean only among instrumented methods) which forms the basis of the stack information recorded alongside the inputs/outputs.
Python call stacks are implementation dependent and we do not expect to operate on anything other than CPython.
Python creates a fresh empty stack for each thread. Because of this, we need special handling of each thread created to make sure it keeps a hold of the stack prior to thread creation. Right now we do this in our threading utility class TP but a more complete solution may be the instrumentation of threading.Thread class.
contextvars -- LangChain uses these to manage contexts such as those used for instrumenting/tracking LLM usage. These can be used to manage call stack information like we do. The drawback is that these are not threadsafe or at least need instrumenting thread creation. We have to do a similar thing by requiring threads created by our utility package which does stack management instead of contextvar management.
NOTE(piotrm): it seems to be standard thing to do to copy the contextvars into new threads so it might be a better idea to use contextvars instead of stack inspection.

Most of the examples included within trulens require additional packages not installed alongside trulens. You may be prompted to install them (with pip). The requirements file trulens/requirements.optional.txt contains the list of optional packages and their use if you'd like to install them all in one go.
To handle optional packages and provide clearer instructions to the user, we employ a context-manager-based scheme (see utils/imports.py) to import packages that may not be installed. The basic form of such imports can be seen in __init__.py:
with OptionalImports(messages=REQUIREMENT_LLAMA):\n from trulens.apps.llamaindex import TruLlama\n
This makes it so that TruLlama gets defined subsequently even if the import fails (because tru_llama imports llama_index which may not be installed). However, if the user imports TruLlama (via __init__.py) and tries to use it (call it, look up attribute, etc), the will be presented a message telling them that llama-index is optional and how to install it:
ModuleNotFoundError:\nllama-index package is required for instrumenting llama_index apps.\nYou should be able to install it with pip:\n\n pip install \"llama-index>=v0.9.14.post3\"\n
If a user imports directly from TruLlama (not by way of __init__.py), they will get that message immediately instead of upon use due to this line inside tru_llama.py:
This checks that the optional import system did not return a replacement for llama_index (under a context manager earlier in the file).
If used in conjunction, the optional imports context manager and assert_installed check can be simplified by storing a reference to to the OptionalImports instance which is returned by the context manager entrance:
with OptionalImports(messages=REQUIREMENT_LLAMA) as opt:\n import llama_index\n ...\n\nopt.assert_installed(llama_index)\n
assert_installed also returns the OptionalImports instance on success so assertions can be chained:

In the subsequent deprecated period of no less than 6 weeks, the use of that component will produce an error after the deprecation message. After these two periods, the deprecated capability will be completely removed.
Deprecation Process
0-6 weeks: Deprecation warning
6-12 weeks: Deprecation message and error
12+ weeks: Removal
Changes that result in non-backwards compatible functionality are also reflected in the version numbering. In such cases, the appropriate level version change will occur at the introduction of the warning period.
Starting 1.0, the trulens_eval package is being deprecated in favor of trulens and several associated required and optional packages. See trulens_eval migration for details.
Warning period: 2024-09-01 (trulens-eval==1.0.1) to 2024-10-14. Backwards compatibility during the warning period is provided by the new content of the trulens_eval package which provides aliases to the features in their new locations. See trulens_eval.
Deprecated period: 2024-10-14 to 2025-12-01. Usage of trulens_eval will produce errors indicating deprecation.
Removed expected 2024-12-01 Installation of the latest version of trulens_eval will be an error itself with a message that trulens_eval is no longer maintained.
Major new features are introduced to TruLens first in the form of experimental previews. Such features are indicated by the prefix experimental_. For example, the OTEL exporter for TruSession is specified with the experimental_otel_exporter parameter. Some features require additionally setting a flag before they are enabled. This is controlled by the TruSession.experimental_{enable,disable}_feature method:
from trulens.core.session import TruSession\nsession = TruSession()\nsession.experimental_enable_feature(\"otel_tracing\")\n\n# or\nfrom trulens.core.experimental import Feature\nsession.experimental_disable_feature(Feature.OTEL_TRACING)\n
If an experimental parameter like experimental_otel_exporter is used, some experimental flags may be set. For the OTEL exporter, the OTEL_EXPORTER flag is required and will be set.
Some features cannot be changed after some stages in the typical TruLens use-cases. OTEL tracing, for example, cannot be disabled once an app has been instrumented. An error will result in an attempt to change the feature after it has been \"locked\" by irreversible steps like instrumentation.
"},{"location":"trulens/contributing/policies/#experimental-features-pipeline","title":"Experimental Features Pipeline","text":"
While in development, the experimental features may change in significant ways. Eventually experimental features get adopted or removed.
For removal, experimental features do not have a deprecation period and will produce \"deprecated\" errors instead of warnings.
For adoption, the feature will be integrated somewhere in the API without the experimental_ prefix and use of that prefix/flag will instead raise an error indicating where in the stable API that feature relocated.

In this release, we re-aligned the groundedness feedback function with other LLM-based feedback functions. It's now faster and easier to define a groundedness feedback function, and can be done with a standard LLM provider rather than importing groundedness on its own. In addition, the custom groundedness aggregation required is now done by default.
Before:
from trulens_eval.feedback.provider.openai import OpenAI\nfrom trulens_eval.feedback import Groundedness\n\nprovider = OpenAI() # or any other LLM-based provider\ngrounded = Groundedness(groundedness_provider=provider)\nf_groundedness = (\n Feedback(grounded.groundedness_measure_with_cot_reasons, name = \"Groundedness\")\n .on(Select.RecordCalls.retrieve.rets.collect())\n .on_output()\n .aggregate(grounded.grounded_statements_aggregator)\n)\n
In natural language text, style/format proper names using italics if available. In Markdown, this can be done with a single underscore character on both sides of the term. In unstyled text, use the capitalization as below. This does not apply when referring to things like package names, classes, methods.
See pyproject.toml section [tool.ruff.lint.isort] on tooling to organize import statements.
Generally import modules only as per https://google.github.io/styleguide/pyguide.html#22-imports. That us:
from trulens.schema.record import Record # don't do this\nfrom trulens.schema import record as mod_record # do this instead\n
This prevents the record module from being loaded until something inside it is needed. If your uses of mod_record.Record are inside functions, this loading can be delayed as far as the execution of that function.
Import and rename modules:
from trulens.schema import record # don't do this\nfrom trulens.schema import record as record_schema # do this\n
This is especially important for module names which might cause name collisions with other things such as variables named record.
Keep module renames consistent:
from trulens.schema import X as X_schema\nfrom trulens.utils import X as X_utils\n\n# if X is inside some category of module Y:\nfrom trulens...Y import Y as X_Y\n# otherwise if X is not in some category of modules:\nfrom trulens... import X as mod_X\n
If an imported module is only used in type annotations, import it inside a TYPE_CHECKING block:
from typing import TYPE_CHECKING\n\nif TYPE_CHECKING:\n from trulens.schema import record as record_schema\n
Do not create exportable aliases (an alias that is listed in __all__ and refers to an element from some other module). Don't import aliases. Type aliases, even exportable ones are ok:
Circular imports may become an issue (error when executing your/trulens code, indicated by phrase \"likely due to circular imports\"). The Import guideline above may help alleviate the problem. A few more things can help:
Use annotations feature flag:
from __future__ import annotations\n
However, if your module contains pydantic models, you may need to run model_rebuild:
from __future__ import annotations\n\n...\n\nclass SomeModel(pydantic.BaseModel):\n\n some_attribute: some_module.SomeType\n\n...\n\nSomeModel.model_rebuild()\n
If you have multiple mutually referential models, you may need to rebuild only after all are defined.

\"\"\"Summary line.\n\nMore details if necessary.\n\nExamples:\n\n```python\n# example if needed\n```\n\nAttrs:\n attribute_name: Description.\n\n attribute_name: Description.\n\"\"\"\n
For pydantic classes, provide the attribute description as a long string right after the attribute definition:
class SomeModel(pydantic.BaseModel)\n \"\"\"Class summary\n\n Class details.\n \"\"\"\n\n attribute: Type = defaultvalue # or pydantic.Field(...)\n \"\"\"Summary as first sentence.\n\n Details as the rest.\n \"\"\"\n\n cls_attribute: typing.ClassVar[Type] = defaultvalue # or pydantic.Field(...)\n \"\"\"Summary as first sentence.\n\n Details as the rest.\n \"\"\"\n\n _private_attribute: Type = pydantic.PrivateAttr(...)\n \"\"\"Summary as first sentence.\n\n Details as the rest.\n \"\"\"\n

Note that the types are automatically filled in by docs generator from the function signature.
Always indicate code type in code blocks as in python in
```python\n# some python here\n```\n
Relevant types are python, typescript, json, shell, markdown. Examples below can serve as a test of the markdown renderer you are viewing these instructions with.
Static tests run on multiple versions of python: 3.8, 3.9, 3.10, 3.11, and being a subset of unit tests, are also run on latest supported python, 3.12 . Some tests that require all optional packages to be installed run only on 3.11 as the latter python version does not support some of those optional packages.
This is a (likely incomplete) list of hacks present in the trulens library. They are likely a source of debugging problems so ideally they can be addressed/removed in time. This document is to serve as a warning in the meantime and a resource for hard-to-debug issues when they arise.
In notes below, \"HACK###\" can be used to find places in the code where the hack lives.
See instruments.py docstring for discussion why these are done.
Stack walking removed in favor of contextvars in 1.0.3. We inspect the call stack in process of tracking method invocation. It may be possible to replace this with contextvars.
\"HACK012\" -- In the optional imports scheme, we have to make sure that imports that happen from outside of trulens raise exceptions instead of producing dummies without raising exceptions.
See instruments.py docstring for discussion why these are done.
We override and wrap methods from other libraries to track their invocation or API use. Overriding for tracking invocation is done in the base instruments.py:Instrument class while for tracking costs are in the base Endpoint class.
\"HACK009\" -- Cannot reliably determine whether a function referred to by an object that implements __call__ has been instrumented. Hacks to avoid warnings about lack of instrumentation.
Fixed as of llama_index 0.9.26 or near there. \"HACK001\" -- trace_method decorator in llama_index does not preserve function signatures; we hack it so that it does.
\"HACK006\" -- endpoint needs to be added as a keyword arg with default value in some __init__ because pydantic overrides signature without default value otherwise.
\"HACK005\" -- model_validate inside WithClassInfo is implemented in decorated method because pydantic doesn't call it otherwise. It is uncertain whether this is a pydantic bug.
We dump attributes marked to be excluded by pydantic except our own classes. This is because some objects are of interest despite being marked to exclude. Example: RetrievalQA.retriever in langchain.
\"HACK004\" -- Outdated, need investigation whether it can be removed.
Partially fixed with asynchro module: async/sync code duplication -- Many of our methods are almost identical duplicates due to supporting both async and synced versions. Having trouble with a working approach to de-duplicated the identical code.
Fixed in endpoint code: \"HACK008\" -- async generator -- Some special handling is used for tracking costs when async generators are involved. See feedback/provider/endpoint/base.py.
\"HACK010\" -- cannot tell whether something is a coroutine and need additional checks in sync/desync.
\"HACK011\" -- older pythons don't allow use of Future as a type constructor in annotations. We define a dummy type Future in older versions of python to circumvent this but have to selectively import it to make sure type checking and mkdocs is done right.
\"HACK012\" -- same but with Queue.
Similarly, we define NoneType for older python versions.
\"HACK013\" -- when using from __future__ import annotations for more convenient type annotation specification, one may have to call pydantic's BaseModel.model_rebuild after all types references in annotations in that file have been defined for each model class that uses type annotations that reference types defined after its own definition (i.e. \"forward refs\").
\"HACK014\" -- cannot from trulens import schema in some places due to strange interaction with pydantic. Results in:
AttributeError: module 'pydantic' has no attribute 'v1'\n
It might be some interaction with from __future__ import annotations and/or OptionalImports.
This is a section heading page. It is presently unused. We can add summaries of the content in this section here then uncomment out the appropriate line in mkdocs.yml to include this section summary in the navigation bar.
For cases where argument specification names more than one value as an input, aggregation can be used.
Consider this feedback example:
# Context relevance between question and each context chunk.\nf_context_relevance = (\n Feedback(provider.context_relevance_with_cot_reasons, name = \"Context Relevance\")\n .on(Select.RecordCalls.retrieve.args.query)\n .on(Select.RecordCalls.retrieve.rets)\n .aggregate(np.mean)\n)\n
The last line aggregate(numpy.min) specifies how feedback outputs are to be aggregated. This only applies to cases where the argument specification names more than one value for an input. The second specification, for statement was of this type.
The input to aggregate must be a method which can be imported globally. This function is called on the float results of feedback function evaluations to produce a single float.
The default is numpy.mean.

Measuring the performance of LLM apps is a critical step in the path from development to production. You would not move a traditional ML system to production without first gaining confidence by measuring its accuracy on a representative test set.
However unlike in traditional machine learning, ground truth is sparse and often entirely unavailable.
Without ground truth on which to compute metrics on our LLM apps, feedback functions can be used to compute metrics for LLM applications.
"},{"location":"trulens/evaluation/feedback_functions/#what-is-a-feedback-function","title":"What is a feedback function?","text":"
Feedback functions, analogous to labeling functions, provide a programmatic method for generating evaluations on an application run. In our view, this method of evaluations is far more useful than general benchmarks because they measure the performance of your app, on your data, for your users.
Important Concept
TruLens constructs feedback functions by combining more general models, known as the feedback provider, and feedback implementation made up of carefully constructed prompts and custom logic tailored to perform a particular evaluation task.
This construction is composable and extensible.
Composable meaning that the user can choose to combine any feedback provider with any feedback implementation.
Extensible meaning that the user can extend a feedback provider with custom feedback implementations of the user's choosing.
Example
In a high stakes domain requiring evaluating long chunks of context, the user may choose to use a more expensive SOTA model.
In lower stakes, higher volume scenarios, the user may choose to use a smaller, cheaper model as the provider.
In either case, any feedback provider can be combined with a TruLens feedback implementation to ultimately compose the feedback function.
"},{"location":"trulens/evaluation/feedback_functions/anatomy/","title":"\ud83e\uddb4 Anatomy of Feedback Functions","text":"
The Feedback class contains the starting point for feedback function specification and evaluation. A typical use-case looks like this:
# Context relevance between question and each context chunk.\nf_context_relevance = (\n Feedback(\n provider.context_relevance_with_cot_reasons,\n name=\"Context Relevance\"\n )\n .on(Select.RecordCalls.retrieve.args.query)\n .on(Select.RecordCalls.retrieve.rets)\n .aggregate(numpy.mean)\n)\n
The provider is the back-end on which a given feedback function is run. Multiple underlying models are available througheach provider, such as GPT-4 or Llama-2. In many, but not all cases, the feedback implementation is shared cross providers (such as with LLM-based evaluations).
OpenAI.context_relevance is an example of a feedback function implementation.
Feedback implementations are simple callables that can be run on any arguments matching their signatures. In the example, the implementation has the following signature:
That is, context_relevance is a plain python method that accepts the prompt and context, both strings, and produces a float (assumed to be between 0.0 and 1.0).
The next line, on_input_output, specifies how the context_relevance arguments are to be determined from an app record or app definition. The general form of this specification is done using on but several shorthands are provided. For example, on_input_output states that the first two argument to context_relevance (prompt and context) are to be the main app input and the main output, respectively.
Read more about argument specification and selector shortcuts.
The last line aggregate(numpy.mean) specifies how feedback outputs are to be aggregated. This only applies to cases where the argument specification names more than one value for an input. The second specification, for statement was of this type. The input to aggregate must be a method which can be imported globally. This requirement is further elaborated in the next section. This function is called on the float results of feedback function evaluations to produce a single float. The default is numpy.mean.
TruLens constructs feedback functions by a feedback provider, and feedback implementation.
This page documents the feedback implementations available in TruLens.
Feedback functions are implemented in instances of the Provider class. They are made up of carefully constructed prompts and custom logic tailored to perform a particular evaluation task.
The implementation of generation-based feedback functions can consist of:
Instructions to a generative model (LLM) on how to perform a particular evaluation task. These instructions are sent to the LLM as a system message, and often consist of a rubric.
A template that passes the arguments of the feedback function to the LLM. This template containing the arguments of the feedback function is sent to the LLM as a user message.
A method for parsing, validating, and normalizing the output of the LLM, accomplished by generate_score.
Custom Logic to perform data preprocessing tasks before the LLM is called for evaluation.
Additional logic to perform postprocessing tasks using the LLM output.
TruLens can also provide reasons using chain-of-thought methodology. Such implementations are denoted by method names ending in _with_cot_reasons. These implementations illicit the LLM to provide reasons for its score, accomplished by generate_score_and_reasons.

Running \"chain of thought evaluations\" is another use case for extending providers. Doing so follows a similar process as above, where the base provider (such as AzureOpenAI) is subclassed.
For this case, the method generate_score_and_reasons can be used to extract both the score and chain of thought reasons from the LLM response.
To use this method, the prompt used should include the COT_REASONS_TEMPLATE available from the TruLens prompts library (trulens.feedback.prompts).

Feedback functions are an extensible framework for evaluating LLMs. You can add your own feedback functions to evaluate the qualities required by your application by simply creating a new provider class and feedback function in your notebook. If your contributions would be useful for others, we encourage you to contribute to TruLens!
Feedback functions are organized by model provider into Provider classes.
The process for adding new feedback functions is:
Create a new Provider class or locate an existing one that applies to your feedback function. If your feedback function does not rely on a model provider, you can create a standalone class. Add the new feedback function method to your selected class. Your new method can either take a single text (str) as a parameter or both prompt (str) and response (str). It should return a float between 0 (worst) and 1 (best).
In addition to calling your own methods, you can also extend stock feedback providers (such as OpenAI, AzureOpenAI, Bedrock) to custom feedback implementations. This can be especially useful for tweaking stock feedback functions, or running custom feedback function prompts while letting TruLens handle the backend LLM provider.
This is done by subclassing the provider you wish to extend, and using the generate_score method that runs the provided prompt with your specified provider, and extracts a float score from 0-1. Your prompt should request the LLM respond on the scale from 0 to 10, then the generate_score method will normalize to 0-1.
Trulens also supports multi-output feedback functions. As a typical feedback function will output a float between 0 and 1, multi-output should output a dictionary of output_key to a float between 0 and 1. The feedbacks table will display the feedback with column feedback_name:::outputkey
Uses Huggingface's truera/context_relevance model, a model that uses computes the relevance of a given context to the prompt. The model can be found at https://huggingface.co/truera/context_relevance.
A measure to track if the source material supports each sentence in the statement using an NLI model.
First the response will be split into statements using a sentence tokenizer.The NLI model will process each statement using a natural language inference model, and will use the entire source.
Evaluates the hallucination score for a combined input of two statements as a float 0<x<1 representing a true/false boolean. if the return is greater than 0.5 the statement is evaluated as true. if the return is less than 0.5 the statement is evaluated as a hallucination.
Example
from trulens.providers.huggingface import Huggingface\nhuggingface_provider = Huggingface()\n\nscore = huggingface_provider.hallucination_evaluator(\"The sky is blue. [SEP] Apples are red , the grass is green.\")\n
Uses Huggingface's papluca/xlm-roberta-base-language-detection model. A function that uses language detection on text1 and text2 and calculates the probit difference on the language detected on text1. The function is: 1.0 - (|probit_language_text1(text1) - probit_language_text1(text2))
hugs = Huggingface()\n\n# Define a pii_detection feedback function using HuggingFace.\nf_pii_detection = Feedback(hugs.pii_detection).on_input()\n
The on(...) selector can be changed. See Feedback Function Guide : Selectors
Args: text: A text prompt that may contain a name.
Returns: Tuple[float, str]: A tuple containing a the likelihood that a PII is contained in the input text and a string containing what PII is detected (if any).
Out of the box feedback functions calling OpenAI APIs. Additionally, all feedback functions listed in the base LLMProvider class can be run with OpenAI.

Uses chat completion model. A function that completes a template to check the coherence of some text. Prompt credit to LangChain Eval. Also uses chain of thought methodology and emits the reasons.
Uses chat completion model. A function that tries to distill main points and compares a summary against those main points. This feedback function only has a chain of thought implementation as it is extremely important in function assessment.
Uses chat completion model. A function that completes a template to check the relevance of the context to the question. Also uses chain of thought methodology and emits the reasons.
Returns: float: A value between 0 and 1. 0 being \"not relevant\" and 1 being \"relevant\". Dict[str, float]: A dictionary containing the confidence score.
Uses chat completion model. A function that completes a template to check the relevance of the context to the question. Also uses chain of thought methodology and emits the reasons.
Uses chat completion model. A function that completes a template to check the controversiality of some text. Prompt credit to Langchain Eval. Also uses chain of thought methodology and emits the reasons.
Uses chat completion model. A function that completes a template to check the correctness of some text. Prompt credit to LangChain Eval. Also uses chain of thought methodology and emits the reasons.
Uses chat completion model. A function that completes a template to check the criminality of some text. Prompt credit to LangChain Eval. Also uses chain of thought methodology and emits the reasons.
To further explain how the function works under the hood, consider the statement:
\"Hi. I'm here to help. The university of Washington is a public research university. UW's connections to major corporations in Seattle contribute to its reputation as a hub for innovation and technology\"
The function will split the statement into its component sentences:

The LLM will then process the statement, to assess the groundedness of the statement.

The LLM will process each statement, using chain of thought methodology to emit the reasons.
In the case of abstentions, such as 'I do not know', the LLM will be asked to consider the answerability of the question given the source material.
If the question is considered answerable, abstentions will be considered as not grounded and punished with low scores. Otherwise, unanswerable abstentions will be considered grounded.

TruLens constructs feedback functions by combining more general models, known as the feedback provider, and feedback implementation made up of carefully constructed prompts and custom logic tailored to perform a particular evaluation task.
This page documents the feedback providers available in TruLens.
There are three categories of such providers as well as combination providers that make use of one or more of these providers to offer additional feedback functions based capabilities of the constituent providers.
Feedback selection is the process of determining which components of your application to evaluate.
This is useful because today's LLM applications are increasingly complex. Chaining together components such as planning, retrievel, tool selection, synthesis, and more; each component can be a source of error.
This also makes the instrumentation and evaluation of LLM applications inseparable. To evaluate the inner components of an application, we first need access to them.
As a reminder, a typical feedback definition looks like this:
on_input_output is one of many available shortcuts to simplify the selection of components for evaluation. We'll cover that in a later section.
The selector, on_input_output, specifies how the language_match arguments are to be determined from an app record or app definition. The general form of this specification is done using on but several shorthands are provided. on_input_output states that the first two argument to language_match (text1 and text2) are to be the main app input and the main output, respectively.
This flexibility to select and evaluate any component of your application allows the developer to be unconstrained in their creativity. The evaluation framework should not designate how you can build your app.
LLM applications come in all shapes and sizes and with a variety of different control flows. As a result it\u2019s a challenge to consistently evaluate parts of an LLM application trace.
Therefore, we\u2019ve adapted the use of lenses to refer to parts of an LLM stack trace and use those when defining evaluations. For example, the following lens refers to the input to the retrieve step of the app called query.
Example
Select.RecordCalls.retrieve.args.query\n
Such lenses can then be used to define evaluations as so:
Example
# Context relevance between question and each context chunk.\nf_context_relevance = (\n Feedback(provider.context_relevance_with_cot_reasons, name = \"Context Relevance\")\n .on(Select.RecordCalls.retrieve.args.query)\n .on(Select.RecordCalls.retrieve.rets)\n .aggregate(np.mean)\n)\n
In most cases, the Select object produces only a single item but can also address multiple items.
For example: Select.RecordCalls.retrieve.args.query refers to only one item.
However, Select.RecordCalls.retrieve.rets refers to multiple items. In this case, the documents returned by the retrieve method. These items can be evaluated separately, as shown above, or can be collected into an array for evaluation with .collect(). This is most commonly used for groundedness evaluations.
Example
f_groundedness = (\n Feedback(provider.groundedness_measure_with_cot_reasons, name = \"Groundedness\")\n .on(Select.RecordCalls.retrieve.rets.collect())\n .on_output()\n)\n
Selectors can also access multiple calls to the same component. In agentic applications, this is an increasingly common practice. For example, an agent could complete multiple calls to a retrieve method to complete the task required.
For example, the following method returns only the returned context documents from the first invocation of retrieve.
context = Select.RecordCalls.retrieve.rets.rets[:]\n# Same as context = context_method[0].rets[:]\n
Alternatively, adding [:] after the method name retrieve returns context documents from all invocations of retrieve.
"},{"location":"trulens/evaluation/feedback_selectors/selecting_components/#understanding-the-structure-of-your-app","title":"Understanding the structure of your app","text":"
Because LLM apps have a wide variation in their structure, the feedback selector construction can also vary widely. To construct the feedback selector, you must first understand the structure of your application.
In python, you can access the JSON structure with with_record methods and then calling layout_calls_as_app.
The application structure can also be viewed in the TruLens user interface. You can view this structure on the Evaluations page by scrolling down to the Timeline.
The top level record also contains these helper accessors
RecordInput = Record.main_input -- points to the main input part of a Record. This is the first argument to the root method of an app (for LangChain Chains this is the __call__ method).
RecordOutput = Record.main_output -- points to the main output part of a Record. This is the output of the root method of an app (i.e. __call__ for LangChain Chains).
RecordCalls = Record.app -- points to the root of the app-structured mirror of calls in a record. See App-organized Calls Section above.
"},{"location":"trulens/evaluation/feedback_selectors/selecting_components/#multiple-inputs-per-argument","title":"Multiple Inputs Per Argument","text":"
As in the f_context_relevance example, a selector for a single argument may point to more than one aspect of a record/app. These are specified using the slice or lists in key/index positions. In that case, the feedback function is evaluated multiple times, its outputs collected, and finally aggregated into a main feedback result.
The collection of values for each argument of feedback implementation is collected and every combination of argument-to-value mapping is evaluated with a feedback definition. This may produce a large number of evaluations if more than one argument names multiple values. In the dashboard, all individual invocations of a feedback implementation are shown alongside the final aggregate result.

When evaluating a feedback function, Records are augmented with app/component calls. For example, if the instrumented app contains a component combine_docs_chain then app.combine_docs_chain will contain calls to methods of this component. app.combine_docs_chain._call will contain a RecordAppCall (see schema.py) with information about the inputs/outputs/metadata regarding the _call call to that component. Selecting this information is the reason behind the Select.RecordCalls alias.
You can inspect the components making up your app via the App method print_instrumented.
on_input_output is one of many available shortcuts to simplify the selection of components for evaluation.
The selector, on_input_output, specifies how the language_match arguments are to be determined from an app record or app definition. The general form of this specification is done using on but several shorthands are provided. on_input_output states that the first two argument to language_match (text1 and text2) are to be the main app input and the main output, respectively.
Several utility methods starting with .on provide shorthands:
on_input(arg) == on_prompt(arg: Optional[str]) -- both specify that the next unspecified argument or arg should be the main app input.
on_output(arg) == on_response(arg: Optional[str]) -- specify that the next argument or arg should be the main app output.
on_input_output() == on_input().on_output() -- specifies that the first two arguments of implementation should be the main app input and main app output, respectively.
on_default() -- depending on signature of implementation uses either on_output() if it has a single argument, or on_input_output if it has two arguments.
Some wrappers include additional shorthands:

Generating a sufficient test set for evaluating an app is an early change in the development phase.
TruLens allows you to generate a test set of a specified breadth and depth, tailored to your app and data. Resulting test set will be a list of test prompts of length depth, for breadth categories of prompts. Resulting test set will be made up of breadth X depth prompts organized by prompt category.
{'Code implementation': [\n 'What are the steps to follow when implementing code based on the provided instructions?',\n 'What is the required format for each file when outputting the content, including all code?'\n ],\n 'Short term memory limitations': [\n 'What is the capacity of short-term memory and how long does it last?',\n 'What are the two subtypes of long-term memory and what types of information do they store?'\n ],\n 'Planning and task decomposition challenges': [\n 'What are the challenges faced by LLMs in adjusting plans when encountering unexpected errors during long-term planning?',\n 'How does Tree of Thoughts extend the Chain of Thought technique for task decomposition and what search processes can be used in this approach?'\n ]\n}\n
Optionally, you can also provide a list of examples (few-shot) to guide the LLM app to a particular type of question.
Example:
examples = [\n \"What is sensory memory?\",\n \"How much information can be stored in short term memory?\"\n]\n\nfewshot_test_set = test.generate_test_set(\n test_breadth = 3,\n test_depth = 2,\n examples = examples\n)\nfewshot_test_set\n
Returns:

"},{"location":"trulens/evaluation/running_feedback_functions/existing_data/","title":"Running on existing data","text":"
In many cases, developers have already logged runs of an LLM app they wish to evaluate or wish to log their app using another system. Feedback functions can also be run on existing data, independent of the recorder.
At the most basic level, feedback implementations are simple callables that can be run on any arguments matching their signatures like so:
Running the feedback implementation in isolation will not log the evaluation results in TruLens.
In the case that you have already logged a run of your application with TruLens and have the record available, the process for running an (additional) evaluation on that record is by using tru.run_feedback_functions:
tru_rag = TruCustomApp(rag, app_name=\"RAG\", app_version=\"v1\")\n\nresult, record = tru_rag.with_record(rag.query, \"How many professors are at UW in Seattle?\")\nfeedback_results = tru.run_feedback_functions(record, feedbacks=[f_lang_match, f_qa_relevance, f_context_relevance])\ntru.add_feedbacks(feedback_results)\n
If your application was run (and logged) outside of TruLens, TruVirtual can be used to ingest and evaluate the logs.
The first step to loading your app logs into TruLens is creating a virtual app. This virtual app can be a plain dictionary or use our VirtualApp class to store any information you would like. You can refer to these values for evaluating feedback.
virtual_app = dict(\n llm=dict(\n modelname=\"some llm component model name\"\n ),\n template=\"information about the template I used in my app\",\n debug=\"all of these fields are completely optional\"\n)\nfrom trulens.core import Select, VirtualApp\n\nvirtual_app = VirtualApp(virtual_app) # can start with the prior dictionary\nvirtual_app[Select.RecordCalls.llm.maxtokens] = 1024\n
When setting up the virtual app, you should also include any components that you would like to evaluate in the virtual app. This can be done using the Select class. Using selectors here lets use reuse the setup you use to define feedback functions. Below you can see how to set up a virtual app with a retriever component, which will be used later in the example for feedback evaluation.
from trulens.core import Select\nretriever_component = Select.RecordCalls.retriever\nvirtual_app[retriever_component] = \"this is the retriever component\"\n
Now that you've set up your virtual app, you can use it to store your logged data.
To incorporate your data into TruLens, you have two options. You can either create a Record directly, or you can use the VirtualRecord class, which is designed to help you build records so they can be ingested to TruLens.
The parameters you'll use with VirtualRecord are the same as those for Record, with one key difference: calls are specified using selectors.
In the example below, we add two records. Each record includes the inputs and outputs for a context retrieval component. Remember, you only need to provide the information that you want to track or evaluate. The selectors are references to methods that can be selected for feedback, as we'll demonstrate below.
from trulens.apps.virtual import VirtualRecord\n\n# The selector for a presumed context retrieval component's call to\n# `get_context`. The names are arbitrary but may be useful for readability on\n# your end.\ncontext_call = retriever_component.get_context\n\nrec1 = VirtualRecord(\n main_input=\"Where is Germany?\",\n main_output=\"Germany is in Europe\",\n calls=\n {\n context_call: dict(\n args=[\"Where is Germany?\"],\n rets=[\"Germany is a country located in Europe.\"]\n )\n }\n )\nrec2 = VirtualRecord(\n main_input=\"Where is Germany?\",\n main_output=\"Poland is in Europe\",\n calls=\n {\n context_call: dict(\n args=[\"Where is Germany?\"],\n rets=[\"Poland is a country located in Europe.\"]\n )\n }\n )\n\ndata = [rec1, rec2]\n
Alternatively, suppose we have an existing dataframe of prompts, contexts and responses we wish to ingest.
import pandas as pd\n\ndata = {\n 'prompt': ['Where is Germany?', 'What is the capital of France?'],\n 'response': ['Germany is in Europe', 'The capital of France is Paris'],\n 'context': ['Germany is a country located in Europe.', 'France is a country in Europe and its capital is Paris.']\n}\ndf = pd.DataFrame(data)\ndf.head()\n
To ingest the data in this form, we can iterate through the dataframe to ingest each prompt, context and response into virtual records.
Now that we've ingested constructed the virtual records, we can build our feedback functions. This is done just the same as normal, except the context selector will instead refer to the new context_call we added to the virtual record.
from trulens.providers.openai import OpenAI\nfrom trulens.core import Feedback\n\n# Initialize provider class\nopenai = OpenAI()\n\n# Select context to be used in feedback. We select the return values of the\n# virtual `get_context` call in the virtual `retriever` component. Names are\n# arbitrary except for `rets`.\ncontext = context_call.rets[:]\n\n# Question/statement relevance between question and each context chunk.\nf_context_relevance = (\n Feedback(openai.context_relevance)\n .on_input()\n .on(context)\n)\n
Then, the feedback functions can be passed to TruVirtual to construct the recorder. Most of the fields that other non-virtual apps take can also be specified here.
To finally ingest the record and run feedbacks, we can use add_record.
for record in data:\n virtual_recorder.add_record(rec)\n
To optionally store metadata about your application, you can also pass an arbitrary dict to VirtualApp. This information can also be used in evaluation.
virtual_app = dict(\n llm=dict(\n modelname=\"some llm component model name\"\n ),\n template=\"information about the template I used in my app\",\n debug=\"all of these fields are completely optional\"\n)\n\nfrom trulens.core.schema import Select\nfrom trulens.apps.virtual import VirtualApp\n\nvirtual_app = VirtualApp(virtual_app)\n
This can be particularly useful for storing the components of an LLM app to be later used for evaluation.
retriever_component = Select.RecordCalls.retriever\nvirtual_app[retriever_component] = \"this is the retriever component\"\n
"},{"location":"trulens/evaluation/running_feedback_functions/with_app/","title":"Running with your app","text":"
The primary method for evaluating LLM apps is by running feedback functions with your app.
To do so, you first need to define the wrap the specified feedback implementation with Feedback and select what components of your app to evaluate. Optionally, you can also select an aggregation method.
Once you've defined the feedback functions to run with your application, you can then pass them as a list to the instrumentation class of your choice, along with the app itself. These make up the recorder.
from trulens.apps.langchain import TruChain\n# f_lang_match, f_qa_relevance, f_context_relevance are feedback functions\ntru_recorder = TruChain(\n chain,\n app_name='ChatApplication',\n app_version=\"Chain1\",\n feedbacks=[f_lang_match, f_qa_relevance, f_context_relevance])\n
Now that you've included the evaluations as a component of your recorder, they are able to be run with your application. By default, feedback functions will be run in the same process as the app. This is known as the feedback mode: with_app_thread.
with tru_recorder as recording:\n chain(\"\"What is langchain?\")\n
In addition to with_app_thread, there are a number of other manners of running feedback functions. These are accessed by the feedback mode and included when you construct the recorder, like so:
TruLens relies on feedback functions to score the performance of LLM apps, which are implemented across a variety of LLMs and smaller models. The numerical scoring scheme adopted by TruLens' feedback functions is intuitive for generating aggregated results from eval runs that are easy to interpret and visualize across different applications of interest. However, it begs the question how trustworthy these scores actually are, given they are at their core next-token-prediction-style generation from meticulously designed prompts.
Consequently, these feedback functions face typical large language model (LLM) challenges in rigorous production environments, including prompt sensitivity and non-determinism, especially when incorporating Mixture-of-Experts and model-as-a-service solutions like those from OpenAI, Mistral, and others. Drawing inspiration from works on Judging LLM-as-a-Judge, we outline findings from our analysis of feedback function performance against task-aligned benchmark data. To accomplish this, we first need to align feedback function tasks to relevant benchmarks in order to gain access to large scale ground truth data for the feedback functions. We then are able to easily compute metrics across a variety of implementations and models.
Observing that many summarization benchmarks, such as those found at SummEval, use human annotation of numerical scores, we propose to frame the problem of evaluating groundedness tasks as evaluating a summarization system. In particular, we generate test cases from SummEval.
SummEval is one of the datasets dedicated to automated evaluations on summarization tasks, which are closely related to the groundedness evaluation in RAG with the retrieved context (i.e. the source) and response (i.e. the summary). It contains human annotation of numerical score (1 to 5) comprised of scoring from 3 human expert annotators and 5 crowd-sourced annotators. There are 16 models being used for generation in total for 100 paragraphs in the test set, so there are a total of 16,000 machine-generated summaries. Each paragraph also has several human-written summaries for comparative analysis.
For evaluating groundedness feedback functions, we compute the annotated \"consistency\" scores, a measure of whether the summarized response is factually consistent with the source texts and hence can be used as a proxy to evaluate groundedness in our RAG triad, and normalized to 0 to 1 score as our expected_score and to match the output of feedback functions.

Here we'll set up our golden set as a set of prompts, responses and expected scores stored in test_cases.py. Then, our numeric_difference method will look up the expected score for each prompt/response pair by exact match. After looking up the expected score, we will then take the L1 difference between the actual score and expected score.

This notebook follows an evaluation of a set of test cases generated from human annotated datasets. In particular, we generate test cases from MeetingBank to evaluate our comprehensiveness feedback function.
MeetingBank is one of the datasets dedicated to automated evaluations on summarization tasks, which are closely related to the comprehensiveness evaluation in RAG with the retrieved context (i.e. the source) and response (i.e. the summary). It contains human annotation of numerical score (1 to 5).
For evaluating comprehensiveness feedback functions, we compute the annotated \"informativeness\" scores, a measure of how well the summaries capture all the main points of the meeting segment. A good summary should contain all and only the important information of the source., and normalized to 0 to 1 score as our expected_score and to match the output of feedback functions.

The numerical scoring scheme adopted by TruLens feedback functions is intuitive for generating aggregated results from eval runs that are easy to interpret and visualize across different applications of interest. However, it begs the question how trustworthy these scores actually are, given they are at their core next-token-prediction-style generation from meticulously designed prompts. Consequently, these feedback functions face typical large language model (LLM) challenges in rigorous production environments, including prompt sensitivity and non-determinism, especially when incorporating Mixture-of-Experts and model-as-a-service solutions like those from OpenAI.
Another frequent inquiry from the community concerns the intrinsic semantic significance, or lack thereof, of feedback scores\u2014for example, how one would interpret and instrument with a score of 0.9 when assessing context relevance in a RAG application or whether a harmfulness score of 0.7 from GPT-3.5 equates to the same from Llama-2-7b.
For simpler meta-evaluation tasks, when human numerical scores are available in the benchmark datasets, such as SummEval, it's a lot more straightforward to evaluate feedback functions as long as we can define reasonable correlation between the task of the feedback function and the ones available in the benchmarks. Check out our preliminary work on evaluating our own groundedness feedback functions: https://www.trulens.org/trulens/groundedness_smoke_tests/#groundedness-evaluations and our previous blog, where the groundedness metric in the context of RAG can be viewed as equivalent to the consistency metric defined in the SummEval benchmark. In those cases, calculating MAE between our feedback scores and the golden set's human scores can readily provide insights on how well the groundedness LLM-based feedback functions are aligned with human preferences.
Yet, acquiring high-quality, numerically scored datasets is challenging and costly, a sentiment echoed across institutions and companies working on RLFH dataset annotation.
Observing that many information retrieval (IR) benchmarks use binary labels, we propose to frame the problem of evaluating LLM-based feedback functions (meta-evaluation) as evaluating a recommender system. In essence, we argue the relative importance or ranking based on the score assignments is all you need to achieve meta-evaluation against human golden sets. The intuition is that it is a sufficient proxy to trustworthiness if feedback functions demonstrate discriminative capabilities that reliably and consistently assign items, be it context chunks or generated responses, with weights and ordering closely mirroring human preferences.
In this following section, we illustrate how we conduct meta-evaluation experiments on one of Trulens most widely used feedback functions: context relevance and share how well they are aligned with human preferences in practice.

In many ways, feedbacks can be thought of as LLM apps themselves. Given text, they return some result. Thinking in this way, we can use TruLens to evaluate and track our feedback quality. We can even do this for different models (e.g. gpt-3.5 and gpt-4) or prompting schemes (such as chain-of-thought reasoning).
This notebook follows an evaluation of a set of test cases. You are encouraged to run this on your own and even expand the test cases to evaluate performance on test cases applicable to your scenario or domain.

We can even do this for different models (e.g. gpt-3.5 and gpt-4) or prompting schemes (such as chain-of-thought reasoning).
This notebook follows an evaluation of a set of test cases generated from human annotated datasets. In particular, we generate test cases from SummEval.
SummEval is one of the datasets dedicated to automated evaluations on summarization tasks, which are closely related to the groundedness evaluation in RAG with the retrieved context (i.e. the source) and response (i.e. the summary). It contains human annotation of numerical score (1 to 5) comprised of scoring from 3 human expert annotators and 5 crowd-sourced annotators. There are 16 models being used for generation in total for 100 paragraphs in the test set, so there are a total of 16,000 machine-generated summaries. Each paragraph also has several human-written summaries for comparative analysis.
For evaluating groundedness feedback functions, we compute the annotated \"consistency\" scores, a measure of whether the summarized response is factually consistent with the source texts and hence can be used as a proxy to evaluate groundedness in our RAG triad, and normalized to 0 to 1 score as our expected_score and to match the output of feedback functions.

Info
TruLens 1.0 is now available. Read more and check out the migration guide
General and \ud83e\udd91TruLens-specific concepts.
Agent. A Component of an Application or the entirety of an application that providers a natural language interface to some set of capabilities typically incorporating Tools to invoke or query local or remote services, while maintaining its state via Memory. The user of an agent may be a human, a tool, or another agent. See also Multi Agent System.
Application or App. An \"application\" that is tracked by \ud83e\udd91TruLens. Abstract definition of this tracking corresponds to App. We offer special support for LangChain via TruChain, LlamaIndex via TruLlama, and NeMo Guardrails via TruRails Applications as well as custom apps via TruBasicApp or TruCustomApp, and apps that already come with Traces via TruVirtual.
Chain. A LangChain App.
Chain of Thought. The use of an Agent to deconstruct its tasks and to structure, analyze, and refine its Completions.
Completion, Generation. The process or result of LLM responding to some Prompt.
Component. Part of an Application giving it some capability. Common components include:
Retriever
Memory
Tool
Agent
Prompt Template
LLM
Embedding. A real vector representation of some piece of text. Can be used to find related pieces of text in a Retrieval.
Eval, Evals, Evaluation. Process or result of method that scores the outputs or aspects of a Trace. In \ud83e\udd91TruLens, our scores are real numbers between 0 and 1.
Feedback. See Evaluation.
Feedback Function. A method that implements an Evaluation. This corresponds to Feedback.
Fine-tuning. The process of training an already pre-trained model on additional data. While the initial training of a Large Language Model is resource intensive (read \"large\"), the subsequent fine-tuning may not be and can improve the performance of the LLM on data that sufficiently deviates or specializes its original training data. Fine-tuning aims to preserve the generality of the original and transfer of its capabilities to specialized tasks. Examples include fining-tuning on:
financial articles
medical notes
synthetic languages (programming or otherwise)
While fine-tuning generally requires access to the original model parameters, some model providers give users the ability to fine-tune through their remote APIs.
Generation. See Completion.
Human Feedback. A feedback that is provided by a human, e.g. a thumbs up/down in response to a Completion.
In-Context Learning. The use of examples in an Instruction Prompt to help an LLM generate intended Completions. See also Shot.
Instruction Prompt, System Prompt. A part of a Prompt given to an LLM to complete that contains instructions describing the task that the Completion should solve. Sometimes such prompts include examples of correct or intended completions (see Shots). A prompt that does not include examples is said to be Zero Shot.
Language Model. A model whose tasks is to model text distributions typically in the form of predicting token distributions for text that follows the given prefix. Propriety models usually do not give users access to token distributions and instead Complete a piece of input text via multiple token predictions and methods such as beam search.
LLM, Large Language Model (see Language Model). The Component of an Application that performs Completion. LLM's are usually trained on a large amount of text across multiple natural and synthetic languages. They are also trained to follow instructions provided in their Instruction Prompt. This makes them general in that they can be applied to many structured or unstructured tasks and even tasks which they have not seen in their training data (See Instruction Prompt, In-Context Learning). LLMs can be further improved to rare/specialized settings using Fine-Tuning.
Memory. The state maintained by an Application or an Agent indicating anything relevant to continuing, refining, or guiding it towards its goals. Memory is provided as Context in Prompts and is updated when new relevant context is processed, be it a user prompt or the results of the invocation of some Tool. As Memory is included in Prompts, it can be a natural language description of the state of the app/agent. To limit to size if memory, Summarization is often used.
Multi-Agent System. The use of multiple Agents incentivized to interact with each other to implement some capability. While the term predates LLMs, the convenience of the common natural language interface makes the approach much easier to implement.
Prompt. The text that an LLM completes during Completion. In chat applications. See also Instruction Prompt, Prompt Template.
Prompt Template. A piece of text with placeholders to be filled in in order to build a Prompt for a given task. A Prompt Template will typically include the Instruction Prompt with placeholders for things like Context, Memory, or Application configuration parameters.
Provider. A system that provides the ability to execute models, either LLMs or classification models. In \ud83e\udd91TruLens, Feedback Functions make use of Providers to invoke models for Evaluation.
RAG, Retrieval Augmented Generation. A common organization of Applications that combine a Retrieval with an LLM to produce Completions that incorporate information that an LLM alone may not be aware of.
RAG Triad (\ud83e\udd91TruLens-specific concept). A combination of three Feedback Functions meant to EvaluateRetrieval steps in Applications.
Record. A \"record\" of the execution of a single execution of an app. Single execution means invocation of some top-level app method. Corresponds to Record
Note
This will be renamed to Trace in the future.
Retrieval, Retriever. The process or result (or the Component that performs this) of looking up pieces of text relevant to a Prompt to provide as Context to an LLM. Typically this is done using an Embedding representations.
Selector (\ud83e\udd91TruLens-specific concept). A specification of the source of data from a Trace to use as inputs to a Feedback Function. This corresponds to Lens and utilities Select.
Shot, Zero Shot, Few Shot, <Quantity>-Shot. Zero Shot describes prompts that do not have any examples and only offer a natural language description of the task to be solved, while <Quantity>-Shot indicate some <Quantity> of examples are provided. The \"shot\" terminology predates instruction-based LLM's where techniques then used other information to handle unseed classes such as label descriptions in the seen/trained data. In-context Learning is the recent term that describes the use of examples in Instruction Prompts.
Span. Some unit of work logged as part of a record. Corresponds to current \ud83e\udd91RecordAppCallMethod.
Summarization. The task of condensing some natural language text into a smaller bit of natural language text that preserves the most important parts of the text. This can be targeted towards humans or otherwise. It can also be used to maintain consize Memory in an LLMApplication or Agent. Summarization can be performed by an LLM using a specific Instruction Prompt.
Tool. A piece of functionality that can be invoked by an Application or Agent. This commonly includes interfaces to services such as search (generic search via google or more specific like IMDB for movies). Tools may also perform actions such as submitting comments to github issues. A Tool may also encapsulate an interface to an Agent for use as a component in a larger Application.
Trace. See Record.

Feedback functions, analogous to labeling functions, provide a programmatic method for generating evaluations on an application run. The TruLens implementation of feedback functions wrap a supported provider\u2019s model, such as a relevance model or a sentiment classifier, that is repurposed to provide evaluations. Often, for the most flexibility, this model can be another LLM.
It can be useful to think of the range of evaluations on two axis: Scalable and Meaningful.
In early development stages, we recommend starting with domain expert evaluations. These evaluations are often completed by the developers themselves and represent the core use cases your app is expected to complete. This allows you to deeply understand the performance of your app, but lacks scale.
See this example notebook to learn how to run ground truth evaluations with TruLens.
After you have completed early evaluations and have gained more confidence in your app, it is often useful to gather human feedback. This can often be in the form of binary (up/down) feedback provided by your users. This is more slightly scalable than ground truth evals, but struggles with variance and can still be expensive to collect.
See this example notebook to learn how to log human feedback with TruLens.
Next, it is a common practice to try traditional NLP metrics for evaluations such as BLEU and ROUGE. While these evals are extremely scalable, they are often too syntactic and lack the ability to provide meaningful information on the performance of your app.
"},{"location":"trulens/getting_started/core_concepts/feedback_functions/#medium-language-model-evaluations","title":"Medium Language Model Evaluations","text":"
Medium Language Models (like BERT) can be a sweet spot for LLM app evaluations at scale. This size of model is relatively cheap to run (scalable) and can also provide nuanced, meaningful feedback on your app. In some cases, these models need to be fine-tuned to provide the right feedback for your domain.
TruLens provides a number of feedback functions out of the box that rely on this style of model such as groundedness NLI, sentiment, language match, moderation and more.
"},{"location":"trulens/getting_started/core_concepts/feedback_functions/#large-language-model-evaluations","title":"Large Language Model Evaluations","text":"
Large Language Models can also provide meaningful and flexible feedback on LLM app performance. Often through simple prompting, LLM-based evaluations can provide meaningful evaluations that agree with humans at a very high rate. Additionally, they can be easily augmented with LLM-provided reasoning to justify high or low evaluation scores that are useful for debugging.
Depending on the size and nature of the LLM, these evaluations can be quite expensive at scale.
See this example notebook to learn how to run LLM-based evaluations with TruLens.

TruLens adapts \u2018honest, harmless, helpful\u2019 as desirable criteria for LLM apps from Anthropic. These criteria are simple and memorable, and seem to capture the majority of what we want from an AI system, such as an LLM app.
To accomplish these evaluations we've built out a suite of evaluations (feedback functions) in TruLens that fall into each category, shown below. These feedback functions provide a starting point for ensuring your LLM app is performant and aligned.
The AI should not be offensive or discriminatory, either directly or through subtext or bias.
When asked to aid in a dangerous act (e.g. building a bomb), the AI should politely refuse. Ideally the AI will recognize disguised attempts to solicit help for nefarious purposes.
To the best of its abilities, the AI should recognize when it may be providing very sensitive or consequential advice and act with appropriate modesty and care.
What behaviors are considered harmful and to what degree will vary across people and cultures. It will also be context-dependent, i.e. it will depend on the nature of the use.
The AI should make a clear attempt to perform the task or answer the question posed (as long as this isn\u2019t harmful). It should do this as concisely and efficiently as possible.
Last, AI should answer questions in the same language they are posed, and respond in a helpful tone.
RAGs have become the standard architecture for providing LLMs with context in order to avoid hallucinations. However even RAGs can suffer from hallucination, as is often the case when the retrieval fails to retrieve sufficient context or even retrieves irrelevant context that is then weaved into the LLM\u2019s response.
TruEra has innovated the RAG triad to evaluate for hallucinations along each edge of the RAG architecture, shown below:
The RAG triad is made up of 3 evaluations: context relevance, groundedness and answer relevance. Satisfactory evaluations on each provides us confidence that our LLM app is free from hallucination.
The first step of any RAG application is retrieval; to verify the quality of our retrieval, we want to make sure that each chunk of context is relevant to the input query. This is critical because this context will be used by the LLM to form an answer, so any irrelevant information in the context could be weaved into a hallucination. TruLens enables you to evaluate context relevance by using the structure of the serialized record.
After the context is retrieved, it is then formed into an answer by an LLM. LLMs are often prone to stray from the facts provided, exaggerating or expanding to a correct-sounding answer. To verify the groundedness of our application, we can separate the response into individual claims and independently search for evidence that supports each within the retrieved context.
Last, our response still needs to helpfully answer the original question. We can verify this by evaluating the relevance of the final response to the user input.
"},{"location":"trulens/getting_started/core_concepts/rag_triad/#putting-it-together","title":"Putting it together","text":"
By reaching satisfactory evaluations for this triad, we can make a nuanced statement about our application\u2019s correctness; our application is verified to be hallucination free up to the limit of its knowledge base. In other words, if the vector database contains only accurate information, then the answers provided by the RAG are also accurate.
To see the RAG triad in action, check out the TruLens Quickstart
TruLens provides a broad set of capabilities for evaluating and tracking applications. In addition, TruLens ships with native tools for examining traces and evaluations in the form of a complete dashboard, and components that can be added to streamlit apps.
To view and examine application logs and feedback results, TruLens provides a built-in Streamlit dashboard. That app has two pages, the Leaderboard which displays aggregate feedback results and metadata for each application version, and the Evaluations page where you can more closely examine individual traces and feedback results. This dashboard is launched by run_dashboard, and will run from a database url you specify with TruSession().
Launch the TruLens dashboard
from trulens.dashboard import run_dashboard\nsession = TruSession(database_url = ...) # or default.sqlite by default\nrun_dashboard(session)\n
By default, the dashboard will find and run on an unused port number. You can also specify a port number for the dashboard to run on. The function will output a link where the dashboard is running.
Specify a port
from trulens.dashboard import run_dashboard\nrun_dashboard(port=8502)\n
Note
If you are running in Google Colab, run_dashboard() will output a tunnel website and IP address that can be entered into the tunnel website.
In addition to the complete dashboard, several of the dashboard components can be used on their own and added to existing Streamlit dashboards.
Streamlit is an easy way to create python scripts into shareable web applications, and has become a popular way to interact with generative AI technology. Several TruLens UI components are now accessible for adding to Streamlit dashboards using the TruLens Streamlit module.
Consider the below app.py which consists of a simple RAG application that is already logged and evaluated with TruLens. Notice in particular, that we are getting both the application's response and record.
Simple Streamlit app with TruLens
import streamlit as st\nfrom trulens.core import TruSession\n\nfrom base import rag # a rag app with a query method\nfrom base import tru_rag # a rag app wrapped by trulens\n\nsession = TruSession()\n\ndef generate_and_log_response(input_text):\n with tru_rag as recording:\n response = rag.query(input_text)\n record = recording.get()\n return record, response\n\nwith st.form(\"my_form\"):\n text = st.text_area(\"Enter text:\", \"How do I launch a streamlit app?\")\n submitted = st.form_submit_button(\"Submit\")\n if submitted:\n record, response = generate_and_log_response(text)\n st.info(response)\n
With the record in hand, we can easily add TruLens components to display the evaluation results of the provided record using trulens_feedback. This will display the TruLens feedback result clickable pills as the feedback is available.
Display feedback results
from trulens.dashboard import streamlit as trulens_st\n\nif submitted:\n trulens_st.trulens_feedback(record=record)\n
In addition to the feedback results, we can also display the record's trace to help with debugging using trulens_trace from the TruLens streamlit module.
Display the trace
from trulens.dashboard import streamlit as trulens_st\n\nif submitted:\n trulens_st.trulens_trace(record=record)\n
Last, we can also display the TruLens leaderboard using render_leaderboard from the TruLens streamlit module to understand the aggregate performance across application versions.
Display the application leaderboard
from trulens.dashboard.leaderboard import render_leaderboard\n\nrender_leaderboard()\n
In combination, the streamlit components allow you to make evaluation front-and-center in your app. This is particularly useful for developer playground use cases, or to ensure users of app reliability.

When setting up the virtual app, you should also include any components that you would like to evaluate in the virtual app. This can be done using the Select class. Using selectors here lets use reuse the setup you use to define feedback functions. Below you can see how to set up a virtual app with a retriever component, which will be used later in the example for feedback evaluation.

Now that we've ingested constructed the virtual records, we can build our feedback functions. This is done just the same as normal, except the context selector will instead refer to the new context_call we added to the virtual record.

Wouldn't it be great if we could automatically filter out context chunks with relevance scores below 0.5?
We can do so with the TruLens guardrail, WithFeedbackFilterDocuments. All we have to do is use the method of_retriever to create a new filtered retriever, passing in the original retriever along with the feedback function and threshold we want to use.

In addition to making informed iteration, we can also directly use feedback results as guardrails at inference time. In particular, here we show how to use the context relevance score as a guardrail to filter out irrelevant context before it gets passed to the LLM. This both reduces hallucination and improves efficiency.
To do so, we'll rebuild our RAG using the @context-filter decorator on the method we want to filter, and pass in the feedback function and threshold to use for guardrailing.

Guardrails play a crucial role in ensuring that only high quality output is produced by LLM apps. By setting guardrail thresholds based on feedback functions, we can directly leverage the same trusted evaluation metrics used for observability, at inference time.
Typical guardrails only allow decisions based on the output, and have no impact on the intermediate steps of an LLM application.
"},{"location":"trulens/guardrails/#trulens-guardrails-for-internal-steps","title":"TruLens guardrails for internal steps","text":"
While it is commonly discussed to use guardrails for blocking unsafe or inappropriate output from reaching the end user, TruLens guardrails can also be leveraged to improve the internal processing of LLM apps.
If we consider a RAG, context filter guardrails can be used to evaluate the context relevance of each context chunk, and only pass relevant chunks to the LLM for generation. Doing so reduces the chance of hallucination and reduces token usage.

This document highlights the changes required to move from trulens-eval to trulens.
The biggest change is that the trulens library now consists of several interoperable modules, each of which can be installed and used independently. This allows users to mix and match components to suit their needs without needing to install the entire library.
When running pip install trulens, the following base modules are installed:
trulens-core: core module that provides the main functionality for TruLens.
trulens-feedback: The module that provides LLM-based evaluation and feedback function definitions.
trulens-dashboard: The module that supports the streamlit dashboard and evaluation visualizations.
Furthermore, the following additional modules can be installed separately: - trulens-benchmark: provides benchmarking functionality for evaluating feedback functions on your dataset.
Instrumentation libraries used to instrument specific frameworks like LangChain and LlamaIndex are now packaged separately and imported under the trulens.apps namespace. For example, to use TruChain to instrument a LangChain app, run pip install trulens-apps-langchain and import it as follows:
from trulens.apps.langchain import TruChain\n
Similarly, providers are now packaged separately from the core library. To use a specific provider, install the corresponding package and import it as follows:
from trulens.providers.openai import OpenAI\n
To find a full list of providers, please refer to the API Reference.
As a result of these changes, the package structure for the TruLens varies from TruLens-Eval. Here are some common import changes you may need to make:

TruLens is a framework that helps you instrument and evaluate LLM apps including RAGs and agents.
Because TruLens is tech-agnostic, we offer a few different tools for instrumentation.
TruCustomApp gives you the most power to instrument a custom LLM app, and provides the instrument method.
TruBasicApp is a simple interface to capture the input and output of a basic LLM app.
TruChain instruments LangChain apps. Read more.
TruLlama instruments LlamaIndex apps. Read more.
TruRails instruments NVIDIA Nemo Guardrails apps. Read more.
In any framework you can track (and evaluate) the inputs, outputs and instrumented internals, along with a wide variety of usage metrics and metadata, detailed below:
Record ID (record_id) - automatically generated, track individual application calls
Timestamp (ts) - automatically tracked, the timestamp of the application call
Latency (latency) - the difference between the application call start and end time.
Using @instrument
from trulens.apps.custom import instrument\n\nclass RAG_from_scratch:\n @instrument\n def retrieve(self, query: str) -> list:\n \"\"\"\n Retrieve relevant text from vector store.\n \"\"\"\n\n @instrument\n def generate_completion(self, query: str, context_str: list) -> str:\n \"\"\"\n Generate answer from context.\n \"\"\"\n\n @instrument\n def query(self, query: str) -> str:\n \"\"\"\n Retrieve relevant text given a query, and then generate an answer from the context.\n \"\"\"\n
In cases you do not have access to a class to make the necessary decorations for tracking, you can instead use one of the static methods of instrument, for example, the alternative for making sure the custom retriever gets instrumented is via instrument.method. See a usage example below:
Using instrument.method
from trulens.apps.custom import instrument\nfrom somepackage.from custom_retriever import CustomRetriever\n\ninstrument.method(CustomRetriever, \"retrieve_chunks\")\n\n# ... rest of the custom class follows ...\n
Read more about instrumenting custom class applications in the API Reference
For basic tracking of inputs and outputs, TruBasicApp can be used for instrumentation.
Any text-to-text application can be simply wrapped with TruBasicApp, and then recorded as a context manager.
Using TruBasicApp to log text to text apps
from trulens.apps.basic import TruBasicApp\n\ndef custom_application(prompt: str) -> str:\n return \"a response\"\n\nbasic_app_recorder = TruBasicApp(\n custom_application, app_id=\"Custom Application v1\"\n)\n\nwith basic_app_recorder as recording:\n basic_app_recorder.app(\"What is the phone number for HR?\")\n
For frameworks with deep integrations, TruLens can expose additional internals of the application for tracking. See TruChain and TruLlama for more details.
TruLens provides TruChain, a deep integration with LangChain to allow you to inspect and evaluate the internals of your application built using LangChain. This is done through the instrumentation of key LangChain classes. To see a list of classes instrumented, see Appendix: Instrumented LangChain Classes and Methods.
In addition to the default instrumentation, TruChain exposes the select_context method for evaluations that require access to retrieved context. Exposing select_context bypasses the need to know the json structure of your app ahead of time, and makes your evaluations reusable across different apps.
To instrument an LLM chain, all that's required is to wrap it using TruChain.
Instrument with TruChain
from trulens.apps.langchain import TruChain\n\n# instrument with TruChain\ntru_recorder = TruChain(rag_chain)\n
To properly evaluate LLM apps we often need to point our evaluation at an internal step of our application, such as the retrieved context. Doing so allows us to evaluate for metrics including context relevance and groundedness.
For LangChain applications where the BaseRetriever is used, select_context can be used to access the retrieved text for evaluation.
TruChain also provides async support for LangChain through the acall method. This allows you to track and evaluate async and streaming LangChain applications.
As an example, below is an LLM chain set up with an async callback.
Create an async chain with LCEL
from langchain.callbacks import AsyncIteratorCallbackHandler\nfrom langchain.chains import LLMChain\nfrom langchain.prompts import PromptTemplate\nfrom langchain_openai import ChatOpenAI\nfrom trulens.apps.langchain import TruChain\n\n# Set up an async callback.\ncallback = AsyncIteratorCallbackHandler()\n\n# Setup a simple question/answer chain with streaming ChatOpenAI.\nprompt = PromptTemplate.from_template(\n \"Honestly answer this question: {question}.\"\n)\nllm = ChatOpenAI(\n temperature=0.0,\n streaming=True, # important\n callbacks=[callback],\n)\nasync_chain = LLMChain(llm=llm, prompt=prompt)\n
Once you have created the async LLM chain you can instrument it just as before.
Instrument async apps with TruChain
async_tc_recorder = TruChain(async_chain)\n\nwith async_tc_recorder as recording:\n await async_chain.ainvoke(\n input=dict(question=\"What is 1+2? Explain your answer.\")\n )\n
For examples of using TruChain, check out the TruLens Cookbook

More information about these decorators can be found in the docs/tracking/instrumentation/index.ipynb notebook.
The specific objects (of the above classes) and methods instrumented for a particular app can be inspected using the App.print_instrumented as exemplified in the next cell. Unlike Instrument.print_instrumentation, this function only shows what in an app was actually instrumented.
TruLens provides TruLlama, a deep integration with LlamaIndex to allow you to inspect and evaluate the internals of your application built using LlamaIndex. This is done through the instrumentation of key LlamaIndex classes and methods. To see all classes and methods instrumented, see Appendix: LlamaIndex Instrumented Classes and Methods.
In addition to the default instrumentation, TruLlama exposes the select_context and select_source_nodes methods for evaluations that require access to retrieved context or source nodes. Exposing these methods bypasses the need to know the json structure of your app ahead of time, and makes your evaluations reusable across different apps.
To instrument an Llama-Index query engine, all that's required is to wrap it using TruLlama.
Instrument a Llama-Index Query Engine
from trulens.apps.llamaindex import TruLlama\n\ntru_query_engine_recorder = TruLlama(query_engine)\n\nwith tru_query_engine_recorder as recording:\n print(query_engine.query(\"What did the author do growing up?\"))\n
To properly evaluate LLM apps we often need to point our evaluation at an internal step of our application, such as the retrieved context. Doing so allows us to evaluate for metrics including context relevance and groundedness.
For LlamaIndex applications where the source nodes are used, select_context can be used to access the retrieved text for evaluation.
Evaluating retrieved context for Llama-Index query engines
TruLlama also provides async support for LlamaIndex through the aquery, achat, and astream_chat methods. This allows you to track and evaluate async applications.
As an example, below is an LlamaIndex async chat engine (achat).
Instrument an async Llama-Index app
from llama_index.core import VectorStoreIndex\nfrom llama_index.readers.web import SimpleWebPageReader\nfrom trulens.apps.llamaindex import TruLlama\n\ndocuments = SimpleWebPageReader(html_to_text=True).load_data(\n [\"http://paulgraham.com/worked.html\"]\n)\nindex = VectorStoreIndex.from_documents(documents)\n\nchat_engine = index.as_chat_engine()\n\ntru_chat_recorder = TruLlama(chat_engine)\n\nwith tru_chat_recorder as recording:\n llm_response_async = await chat_engine.achat(\n \"What did the author do growing up?\"\n )\n\nprint(llm_response_async)\n
Just like with other methods, just wrap your streaming query engine with TruLlama and operate like before.
You can also print the response tokens as they are generated using the response_gen attribute.
Instrument a streaming Llama-Index app
tru_chat_engine_recorder = TruLlama(chat_engine)\n\nwith tru_chat_engine_recorder as recording:\n response = chat_engine.stream_chat(\"What did the author do growing up?\")\n\nfor c in response.response_gen:\n print(c)\n

To instrument an LLM chain, all that's required is to wrap it using TruChain.
Instrument a NeMo app
from trulens.apps.nemo import TruRails\n\n# instrument with TruRails\ntru_recorder = TruRails(\n rails,\n app_id=\"my first trurails app\", # optional\n)\n
To properly evaluate LLM apps we often need to point our evaluation at an internal step of our application, such as the retrieved context. Doing so allows us to evaluate for metrics including context relevance and groundedness.
For Nemo applications with a knowledge base, select_context can be used to access the retrieved text for evaluation.
For examples of using TruRails, check out the TruLens Cookbook

The modules, classes, and methods that trulens instruments can be retrieved from the appropriate Instrument subclass.

Additional classes and methods can be instrumented by use of the trulens.core.instruments.Instrument methods and decorators. Examples of such usage can be found in the custom app used in the custom_example.ipynb notebook which can be found in examples/expositional/end2end_apps/custom_app/custom_app.py. More information about these decorators can be found in the docs/trulens/tracking/instrumentation/index.ipynb notebook.
The specific objects (of the above classes) and methods instrumented for a particular app can be inspected using the App.print_instrumented as exemplified in the next cell. Unlike Instrument.print_instrumentation, this function only shows what in an app was actually instrumented.

The simplest method for logging with TruLens is by wrapping with TruChain as shown in the quickstart.
This is done like so:

Making the first call to your wrapped LLM Application will now also produce a log or \"record\" of the chain execution.
Following the request to your app, you can then evaluate LLM quality using feedback functions. This is completed in a sequential call to minimize latency for your application, and evaluations will also be logged to your local machine.
To get feedback on the quality of your LLM, you can use any of the provided feedback functions or add your own.
To assess your LLM quality, you can provide the feedback functions to session.run_feedback() in a list provided to feedback_functions.
In the above example, the feedback function evaluation is done in the same process as the chain evaluation. The alternative approach is the use the provided persistent evaluator started via session.start_deferred_feedback_evaluator. Then specify the feedback_mode for TruChain as deferred to let the evaluator handle the feedback functions.
For demonstration purposes, we start the evaluator here but it can be started in another process.

Examples for tracking and evaluating apps with TruLens. Examples are organized by different frameworks (such as Langchain or Llama-Index), model (including Azure, OSS models and more), vector store, and use case.
The examples in this cookbook are more focused on applying core concepts to external libraries or end to end applications than the quickstarts.

Agents are often useful in the RAG setting to retrieve real-time information to be used for question answering.
This example utilizes the openai functions agent to reliably call and return structured responses from particular tools. Certain OpenAI models have been fine-tuned for this capability to detect when a particular function should be called and respond with the inputs required for that function. Compared to a ReACT framework that generates reasoning and actions in an interleaving manner, this strategy can often be more reliable and consistent.
In either case - as the questions change over time, different agents may be needed to retrieve the most useful context. In this example you will create a langchain agent and use TruLens to identify gaps in tool coverage. By quickly identifying this gap, we can quickly add the missing tools to the application and improve the quality of the answers.

The LangChain EnsembleRetriever takes a list of retrievers as input and ensemble the results of their get_relevant_documents() methods and rerank the results based on the Reciprocal Rank Fusion algorithm. With TruLens, we have the ability to evaluate the context of each component retriever along with the ensemble retriever. This example walks through that process.

When building an LLM application we have hundreds of different models to choose from, all with different costs/latency and performance characteristics. Importantly, performance of LLMs can be heterogeneous across different use cases. Rather than relying on standard benchmarks or leaderboard performance, we want to evaluate an LLM for the use case we need.
Doing this sort of comparison is a core use case of TruLens. In this example, we'll walk through how to build a simple langchain app and evaluate across 3 different models: small flan, large flan and text-turbo-3.

One of the biggest pain-points developers discuss when trying to build useful LLM applications is latency; these applications often make multiple calls to LLM APIs, each one taking a few seconds. It can be quite a frustrating user experience to stare at a loading spinner for more than a couple seconds. Streaming helps reduce this perceived latency by returning the output of the LLM token by token, instead of all at once.
This notebook demonstrates how to monitor a LangChain streaming app with TruLens.

In this example, we build an agent-based app with Llama Index to answer questions with the help of Yelp. We'll evaluate it using a few different feedback functions (some custom, some out-of-the-box)
The first set of feedback functions complete what the non-hallucination triad. However because we're dealing with agents here, we've added a fourth leg (query translation) to cover the additional interaction between the query planner and the agent. This combination provides a foundation for eliminating hallucination in LLM applications.
Query Translation - The first step. Here we compare the similarity of the original user query to the query sent to the agent. This ensures that we're providing the agent with the correct question.
Context or QS Relevance - Next, we compare the relevance of the context provided by the agent back to the original query. This ensures that we're providing context for the right question.
Groundedness - Third, we ensure that the final answer is supported by the context. This ensures that the LLM is not extending beyond the information provided by the agent.
Question Answer Relevance - Last, we want to make sure that the final answer provided is relevant to the user query. This last step confirms that the answer is not only supported but also useful to the end user.
In this example, we'll add two additional feedback functions.
Ratings usage - evaluate if the summarized context uses ratings as justification. Note: this may not be relevant for all queries.
Ground truth eval - we want to make sure our app responds correctly. We will create a ground truth set for this evaluation.
Last, we'll compare the evaluation of this app against a standalone LLM. May the best bot win?

Before we start the evaluator, note that we've logged all of the records including the sub-questions. However we haven't completed any evals yet.
Start the evaluator to generate the feedback results.
In this notebook, we will level up our evaluation using chain of thought reasoning. Chain of thought reasoning through interemediate steps improves LLM's ability to perform complex reasoning - and this includes evaluations. Even better, this reasoning is useful for us as humans to identify and understand new failure modes such as irrelevant retrieval or hallucination.
Second, in this example we will leverage deferred evaluations. Deferred evaluations can be especially useful for cases such as sub-question queries where the structure of our serialized record can vary. By creating different options for context evaluation, we can use deferred evaluations to try both and use the one that matches the structure of the serialized record. Deferred evaluations can be run later, especially in off-peak times for your app.

Hybrid Retrievers are a great way to combine the strengths of different retrievers.

Last, we'll show how guardrails are an alternative approach to achieving the same goal: passing only relevant context to the LLM.

TruLens feedback functions can be used as context filters in place of reranking. This is great for cases when you don't want to deal with another model (the reranker) or in cases when the feedback function is better aligned to human scores than a reranker.

Note that when ImageNodes that have populated text fields are used to build a MultiModalVectorStoreIndex, we can choose to use this text to build embeddings on that will be used for retrieval. To so, we just specify the class attribute is_image_to_text to True.

The images were taken from ASL-Alphabet Kaggle dataset. Note, that they were modified to simply include a label of the associated letter on the hand gesture image. These altered images are what we use as context to the user queries, and they can be downloaded from our google drive (see below cell, which you can uncomment to download the dataset directly from this notebook).
For text context, we use descriptions of each of the hand gestures sourced from https://www.deafblind.com/asl.html. We have conveniently stored these in a json file called asl_text_descriptions.json which is included in the zip download from our google drive.
As in the text-only case, we need to \"attach\" a generator to our index (that can be used as a retriever) to finally assemble our RAG systems. In the multi-modal case however, our generators are Multi-Modal LLMs (or also often referred to as Large Multi-Modal Models or LMM for short). In this notebook, to draw even more comparisons on varied RAG systems, we will use GPT-4V. We can \"attach\" a generator and get an queryable interface for RAG by invoking the as_query_engine method of our indexes.
Let's take a test drive of one these systems. To pretty display the response, we make use of notebook utility function display_query_and_multimodal_response.

Query planning is a useful tool to leverage the ability of LLMs to structure the user inputs into multiple different queries, either sequentially or in parallel before answering the questions. This method improvers the response by allowing the question to be decomposed into smaller, more answerable questions.
Sub-question queries are one such method. Sub-question queries decompose the user input into multiple different sub-questions. This is great for answering complex questions that require knowledge from different documents.
Relatedly, there are a great deal of configurations for this style of application that must be selected. In this example, we'll iterate through several of these choices and evaluate each with TruLens.

Lets consider some feedback functions. We will define two types: a simple language match that checks whether output of the app is in the same language as the input. The second is a set of three for evaluating context retrieval. The setup for these is similar to that for other app types such as langchain except we provide a utility RAG_triad to create the three context retrieval functions for you instead of having to create them separately.
The files created below define a configuration of a rails app adapted from various examples in the NeMo-Guardrails repository. There is nothing unusual about the app beyond the knowledge base here being the TruLens documentation. This means you should be able to ask the resulting bot questions regarding trulens instead of the fictional company handbook as was the case in the originating example.

Next we define output flows that include checks using all 4 feedback functions we registered above. We will need to specify to the Feedback action the sources of feedback function arguments. The selectors for those can be specified manually or by way of utility container RailsActionSelect. The data structure from which selectors pick our feedback inputs contains all of the arguments of NeMo GuardRails custom action methods:
Though not required, we can also use a trulens recorder to monitor our app.

Lets try to make the app respond in a different language than the question to try to get the language match flow to abort the output. Note that the verbose flag in the feedback action we setup in the colang above makes it print out the inputs and output of the function.
Lets check to make sure all 3 RAG feedback functions will run and hopefully pass. Note that the \"stop\" in their flow definitions means that if any one of them fails, no subsequent ones will be tested.

The files created below define a configuration of a rails app adapted from various examples in the NeMo-Guardrails repository. There is nothing unusual about the app beyond the knowledge base here being the trulens documentation. This means you should be able to ask the resulting bot questions regarding trulens instead of the fictional company handbook as was the case in the originating example.
Lets consider some feedback functions. We will define two types: a simple language match that checks whether output of the app is in the same language as the input. The second is a set of three for evaluating context retrieval. The setup for these is similar to that for other app types such as langchain except we provide a utility RAG_triad to create the three context retrieval functions for you instead of having to create them separately.
While feedback can be inspected on the dashboard, you can also retrieve its results in the notebook.

Try out various other interactions to show off the capabilities of the feedback functions. For example, we can try to make the model answer in a different language than our prompt.
[Important] Notice in this example notebook, we are using Assistants API V1 (hence the pinned version of openai below) so that we can evaluate against retrieved source. At some very recent point in time as of April 2024, OpenAI removed the \"quote\" attribute from file citation object in Assistants API V2 due to stability issue of this feature. See response from OpenAI staff https://community.openai.com/t/assistant-api-always-return-empty-annotations/489285/48

Amazon Bedrock is a fully managed service that makes FMs from leading AI startups and Amazon available via an API, so you can choose from a wide range of FMs to find the model that is best suited for your use case.
In this quickstart you will learn how to use AWS Bedrock with all the power of tracking + eval with TruLens.
Note: this example assumes logged in with the AWS CLI. Different authentication methods may change the initial client set up, but the rest should remain the same. To retrieve credentials using AWS sso, you will need to download the aws CLI and run:
aws sso login\naws configure export-credentials\n
The second command will provide you with various keys you need.

SageMaker JumpStart provides a variety of pretrained open source and proprietary models such as Llama-2, Anthropic\u2019s Claude and Cohere Command that can be quickly deployed in the Sagemaker environment. In many cases however, these foundation models are not sufficient on their own for production use cases, needing to be adapted to a particular style or new tasks. One way to surface this need is by evaluating the model against a curated ground truth dataset. Once the need to adapt the foundation model is clear, one could leverage a set of techniques to carry that out. A popular approach is to fine-tune the model on a dataset that is tailored to the use case.
One challenge with this approach is that curated ground truth datasets are expensive to create. In this blog post, we address this challenge by augmenting this workflow with a framework for extensible, automated evaluations. We start off with a baseline foundation model from SageMaker JumpStart and evaluate it with TruLens, an open source library for evaluating & tracking LLM apps. Once we identify the need for adaptation, we can leverage fine-tuning in Sagemaker Jumpstart and confirm improvement with TruLens.
TruLens evaluations make use of an abstraction of feedback functions. These functions can be implemented in several ways, including BERT-style models, appropriately prompted Large Language Models, and more. TruLens\u2019 integration with AWS Bedrock allows you to easily run evaluations using LLMs available from AWS Bedrock. The reliability of Bedrock\u2019s infrastructure is particularly valuable for use in performing evaluations across development and production.
In this demo notebook, we demonstrate how to use the SageMaker Python SDK to deploy pre-trained Llama 2 model as well as fine-tune it for your dataset in domain adaptation or instruction tuning format. We will also use TruLens to identify performance issues with the base model and validate improvement of the fine-tuned model.

In this quickstart, you'll learn how to use the HHEM evaluator feedback function from TruLens in your application. The Vectra HHEM evaluator, or Hughes Hallucination Evaluation Model, is a tool used to determine if a summary produced by a large language model (LLM) might contain hallucinated information.
Purpose: The Vectra HHEM evaluator analyzes both inputs and assigns a score indicating the probability of response containing hallucinations.
Score : The returned value is a floating point number between zero and one that represents a boolean outcome : either a high likelihood of hallucination if the score is less than 0.5 or a low likelihood of hallucination if the score is more than 0.5
e5 embeddings set the SOTA on BEIR and MTEB benchmarks by using only synthetic data and less than 1k training steps. this method achieves strong performance on highly competitive text embedding benchmarks without using any labeled data. Furthermore, when fine-tuned with a mixture of synthetic and labeled data, this model sets new state-of-the-art results on the BEIR and MTEB benchmarks.Improving Text Embeddings with Large Language Models.

In this quickstart you will learn how to use LiteLLM as a feedback function provider.
LiteLLM is a consistent way to access 100+ LLMs such as those from OpenAI, HuggingFace, Anthropic, and Cohere. Using LiteLLM dramatically expands the model availability for feedback functions. Please be cautious in trusting the results of evaluations from models that have not yet been tested.
Specifically in this example we'll show how to use TogetherAI, but the LiteLLM provider can be used to run feedback functions using any LiteLLM supported model. We'll also use Mistral for the embedding and completion model also accessed via LiteLLM. The token usage and cost metrics for models used by LiteLLM will be also tracked by TruLens.
Note: LiteLLM costs are tracked for models included in this litellm community-maintained list.

In this quickstart you will learn build and evaluate a RAG application with Snowflake Arctic.
Building and evaluating RAG applications with Snowflake Arctic offers developers a unique opportunity to leverage a top-tier, enterprise-focused LLM that is both cost-effective and open-source. Arctic excels in enterprise tasks like SQL generation and coding, providing a robust foundation for developing intelligent applications with significant cost savings. Learn more about Snowflake Arctic
In this example, we will use Arctic Embed (snowflake-arctic-embed-m) as our embedding model via HuggingFace, and Arctic, a 480B hybrid MoE LLM for both generation and as the LLM to power TruLens feedback functions. The Arctic LLM is fully-mananaged by Cortex LLM functions
Note, you'll need to have an active Snowflake account to run Cortex LLM functions from Snowflake's data warehouse.

Alternatively, we can use Cortex's Python API (documentation) directly to have cleaner interface and avoid constructing SQL commands ourselves. The reason we are invoking the SQL function directly via snowflake_session.sql() is that the response from Cortex's Python API is still experimental and not as feature-rich as the one from SQL function as of the time of writing. i.e. inconsistency issues with structured json outputs and missing usage information have been observed, lack of support for advanced chat-style (multi-message), etc. Below is a minimal example of using Python API instead.

Ground truth agreement: For these set of metrics, we will measure how similar the generated summary is to some human-created ground truth. We will use for different measures: BERT score, BLEU, ROUGE and a measure where an LLM is prompted to produce a similarity score.
Groundedness: For this measure, we will estimate if the generated summary can be traced back to parts of the original transcript.

Now we are ready to wrap our summarization app with TruLens as a TruCustomApp. Now each time it will be called, TruLens will log inputs, outputs and any instrumented intermediate steps and evaluate them ith the feedback functions we created.

The top-level organization of this examples repository is divided into quickstarts, expositions, experimental, and dev. Quickstarts are actively maintained to work with every release. Expositions are verified to work with a set of verified dependencies tagged at the top of the notebook which will be updated at every major release. Experimental examples may break between release. Dev examples are used to develop or test releases.
Quickstarts contain the simple examples for critical workflows to build, evaluate and track your LLM app. These examples are displayed in the TruLens documentation under the \"Getting Started\" section.
This expositional library of TruLens examples is organized by the component of interest. Components include /models, /frameworks and /vector-dbs. Use cases are also included under /use_cases. These examples can be found in TruLens documentation as the TruLens cookbook.

Perhaps if we use metadata filters to create specialized query engines, we can improve the search results and thus, the overall evaluation results.
But it may be clunky to have two separate query engines - then we have to decide which one to use!
Instead, let's use a router query engine to choose the query engine based on the query.

MongoDB Atlas Vector Search is part of the MongoDB platform that enables MongoDB customers to build intelligent applications powered by semantic search over any type of data. Atlas Vector Search allows you to integrate your operational database and vector search in a single, unified, fully managed platform with full vector database capabilities.
You can integrate TruLens with your application built on Atlas Vector Search to leverage observability and measure improvements in your application's search capabilities.
This tutorial will walk you through the process of setting up TruLens with MongoDB Atlas Vector Search and Llama-Index as the orchestrator.
Even better, you'll learn how to use metadata filters to create specialized query engines and leverage a router to choose the most appropriate query engine based on the query.
See MongoDB Atlas/LlamaIndex Quickstart for more details.

Our test set is made up of 2 topics (test breadth), each with 2-3 questions (test depth).
We can store the topic as record level metadata and then test queries from each topic, using tru_query_engine_recorder as a context manager.
We will download a pre-embedding dataset from pinecone-datasets. Allowing us to skip the embedding and preprocessing steps, if you'd rather work through those steps you can find the full notebook here.
We'll format the dataset ready for upsert and reduce what we use to a subset of the full dataset.

We can also see that both the euclidean and dot-product metrics performed at a lower latency than cosine at roughly the same evaluation quality. We can move forward with either. Since Euclidean is already loaded in Pinecone, we'll go with that one.
After doing so, we can view our evaluations for all three LLM apps sitting on top of the different indices. All three apps are struggling with query-statement relevance. In other words, the context retrieved is only somewhat relevant to the original query.
Diagnosis: Hallucination.
Digging deeper into the Query Statement Relevance, we notice one problem in particular with a question about famous dental floss brands. The app responds correctly, but is not backed up by the context retrieved, which does not mention any specific brands.
Using a less powerful model is a common way to reduce hallucination for some applications. We\u2019ll evaluate ada-001 in our next experiment for this purpose.
Changing different components of apps built with frameworks like LangChain is really easy. In this case we just need to call \u2018text-ada-001\u2019 from the langchain LLM store. Adding in easy evaluation with TruLens allows us to quickly iterate through different components to find our optimal app configuration.
with tru_chain_with_sources_recorder as recording:\n for prompt in prompts:\n chain_with_sources(prompt)\n
with tru_chain_with_sources_recorder as recording: for prompt in prompts: chain_with_sources(prompt)
However this configuration with a less powerful model struggles to return a relevant answer given the context provided. For example, when asked \u201cWhich year was Hawaii\u2019s state song written?\u201d, the app retrieves context that contains the correct answer but fails to respond with that answer, instead simply responding with the name of the song.
Note: The way the top_k works with RetrievalQA is that the documents are still retrieved by our semantic search and but only the top_k are passed to the LLM. Howevever TruLens captures all of the context chunks that are being retrieved. In order to calculate an accurate QS Relevance metric that matches what's being passed to the LLM, we need to only calculate the relevance of the top context chunk retrieved.

Our final application has much improved context_relevance, qa_relevance and low latency!

Large Language Models (LLMs) have a hallucination problem. Retrieval Augmented Generation (RAG) is an emerging paradigm that augments LLMs with a knowledge base \u2013 a source of truth set of docs often stored in a vector database like Pinecone, to mitigate this problem. To build an effective RAG-style LLM application, it is important to experiment with various configuration choices while setting up the vector database and study their impact on performance metrics.
The following cell invokes a shell command in the active Python environment for the packages we need to continue with this notebook. You can also run pip install directly in your terminal without the !.

Now that we've build our index we can switch over to LangChain. We need to initialize a LangChain vector store using the same index we just built. For this we will also need a LangChain embedding object, which we initialize like so:
In RAG we take the query as a question that is to be answered by a LLM, but the LLM must answer the question based on the information it is seeing being returned from the vectorstore.
To do this we initialize a RetrievalQA object like so:

Once we\u2019ve set up our app, we should put together our feedback functions. As a reminder, feedback functions are an extensible method for evaluating LLMs. Here we\u2019ll set up 3 feedback functions: context_relevance, qa_relevance, and groundedness. They\u2019re defined as follows:
QS Relevance: query-statement relevance is the average of relevance (0 to 1) for each context chunk returned by the semantic search.
QA Relevance: question-answer relevance is the relevance (again, 0 to 1) of the final answer to the original question.
Groundedness: groundedness measures how well the generated response is supported by the evidence provided to the model where a score of 1 means each sentence is grounded by a retrieved context chunk.

Wrapper of basic apps.
This will be wrapped by instrumentation.
Warning
Because TruWrapperApp may wrap different types of callables, we cannot patch the signature to anything consistent. Because of this, the dashboard/record for this call will have *args, **kwargs instead of what the app actually uses. We also need to adjust the main_input lookup to get the correct signature. See note there.
This is done so we can be aware when new instances are created and is needed for wrapped methods that dynamically create instances of classes we wish to instrument. As they will not be visible at the time we wrap the app, we need to pay attention to new to make a note of them when they are created and the creator's path. This path will be used to place these new instances in the app json structure.
Instantiates a Basic app that makes little assumptions.
Assumes input text and output text.
Example
def custom_application(prompt: str) -> str:\n return \"a response\"\n\nfrom trulens.apps.basic import TruBasicApp\n# f_lang_match, f_qa_relevance, f_context_relevance are feedback functions\ntru_recorder = TruBasicApp(custom_application,\n app_name=\"Custom Application\",\n app_version=\"1\",\n feedbacks=[f_lang_match, f_qa_relevance, f_context_relevance])\n\n# Basic app works by turning your callable into an app\n# This app is accessible with the `app` attribute in the recorder\nwith tru_recorder as recording:\n tru_recorder.app(question)\n\ntru_record = recording.records[0]\n
See Feedback Functions for instantiating feedback functions.
Computed deterministically from app_name and app_version. Leaving it here for it to be dumped when serializing. Also making it read-only as it should not be changed after creation.
Ideally this would be a ClassVar but since we want to check this without instantiating the subclass of AppDefinition that would define it, we cannot use ClassVar.
Info to store about the app and to display in dashboard.
This can be used even if app itself cannot be serialized. app_extra_json, then, can stand in place for whatever data the user might want to keep track of about the app.
Wrap any lazy values in the return value of a method call to invoke handle_done when the value is ready.
This is used to handle library-specific lazy values that are hidden in containers not visible otherwise. Visible lazy values like iterators, generators, awaitables, and async generators are handled elsewhere.
PARAMETER DESCRIPTION rets
The return value of the method call.
TYPE: Any
wrap
A callback to be called when the lazy value is ready. Should return the input value or a wrapped version of it.
TYPE: Callable[[T], T]
on_done
Called when the lazy values is done and is no longer lazy. This as opposed to a lazy value that evaluates to another lazy values. Should return the value or wrapper.
TYPE: Callable[[T], T]
context_vars
The contextvars to be captured by the lazy value. If not given, all contexts are captured.
This is an experimental feature with ongoing work.
Create a copy of the json serialized app with the enclosed app being initialized to its initial state before any records are produced (i.e. blank memory).
Timeout in seconds for waiting for feedback results for each feedback function. Note that this is not the total timeout for this entire blocking call.
TYPE: Optional[float] DEFAULT: None
RETURNS DESCRIPTION List[Record]
A list of records that have been waited on. Note a record will be included even if a feedback computation for it failed or timed out.
This applies to all feedbacks on all records produced by this app. This call will block until finished and if new records are produced while this is running, it will include them.
Try to find retriever components in the given app and return a lens to access the retrieved contexts that would appear in a record were these components to execute.
Call the given async func with the given *args and **kwargs while recording, producing func results.
The record of the computation is available through other means like the database or dashboard. If you need a record of this execution immediately, you can use awith_record or the App as a context manager instead.

Create a dummy record with some of the expected structure without actually invoking the app.
The record is a guess of what an actual record might look like but will be missing information that can only be determined after a call is made.
All args are Record fields except these:
- `record_id` is generated using the default id naming schema.\n- `app_id` is taken from this recorder.\n- `calls` field is constructed based on instrumented methods.\n
This wrapper is the most flexible option for instrumenting an application, and can be used to instrument any custom python class.
Example
Consider a mock question-answering app with a context retriever component coded up as two classes in two python, CustomApp and CustomRetriever:
The core tool for instrumenting these classes is the @instrument decorator. TruLens needs to be aware of two high-level concepts to usefully monitor the app: components and methods used by components. The instrument must decorate each method that the user wishes to track.
The owner classes of any decorated method is then viewed as an app component. In this example, case CustomApp and CustomRetriever are components.
Example:\n ### `example.py`\n\n ```python\n from custom_app import CustomApp\n from trulens.apps.custom import TruCustomApp\n\n custom_app = CustomApp()\n\n # Normal app Usage:\n response = custom_app.respond_to_query(\"What is the capital of Indonesia?\")\n\n # Wrapping app with `TruCustomApp`:\n tru_recorder = TruCustomApp(ca)\n\n # Tracked usage:\n with tru_recorder:\n custom_app.respond_to_query, input=\"What is the capital of Indonesia?\")\n ```\n\n`TruCustomApp` constructor arguments are like in those higher-level\n
apps as well including the feedback functions, metadata, etc.
from trulens.apps.custom import instrument\n\nclass CustomRetriever:\n # NOTE: No restriction on this class either.\n\n @instrument\n def retrieve_chunks(self, data):\n return [\n f\"Relevant chunk: {data.upper()}\", f\"Relevant chunk: {data[::-1]}\"\n ]\n
"},{"location":"reference/trulens/apps/custom/#trulens.apps.custom--instrumenting-3rd-party-classes","title":"Instrumenting 3rd party classes","text":"
In cases you do not have access to a class to make the necessary decorations for tracking, you can instead use one of the static methods of instrument, for example, the alternative for making sure the custom retriever gets instrumented is via:
# custom_app.py`:\n\nfrom trulens.apps.custom import instrument\nfrom some_package.from custom_retriever import CustomRetriever\n\ninstrument.method(CustomRetriever, \"retrieve_chunks\")\n\n# ... rest of the custom class follows ...\n
Uses of huggingface inference APIs are tracked as long as requests are made through the requests class's post method to the URL https://api-inference.huggingface.co .
Tracked (instrumented) components must be accessible through other tracked components. Specifically, an app cannot have a custom class that is not instrumented but that contains an instrumented class. The inner instrumented class will not be found by trulens.
All tracked components are categorized as \"Custom\" (as opposed to Template, LLM, etc.). That is, there is no categorization available for custom components. They will all show up as \"uncategorized\" in the dashboard.
Non json-like contents of components (that themselves are not components) are not recorded or available in dashboard. This can be alleviated to some extent with the app_extra_json argument to TruCustomClass as it allows one to specify in the form of json additional information to store alongside the component hierarchy. Json-like (json bases like string, int, and containers like sequences and dicts are included).

If an instrumented / decorated method's owner object cannot be found when traversing your custom class, you will get a warning. This may be ok in the end but may be indicative of a problem. Specifically, note the \"Tracked\" limitation above. You can also use the app_extra_json argument to App / TruCustomApp to provide a structure to stand in place for (or augment) the data produced by walking over instrumented components to make sure this hierarchy contains the owner of each instrumented method.
The owner-not-found error looks like this:

Make sure it is accessible by traversing app <custom_app.CustomApp object at 0x112a005b0> or provide a bound method for it as TruCustomApp constructor argument `methods_to_instrument`.\nFunction <function CustomTemplate.fill at 0x1779474c0> was not found during instrumentation walk.

Subsequent attempts at with_record/awith_record may result in the \"Empty record\" exception.
Usage tracking not tracking. We presently have limited coverage over which APIs we track and make some assumptions with regards to accessible APIs through lower-level interfaces. Specifically, we only instrument the requests module's post method for the lower level tracking. Please file an issue on github with your use cases so we can work out a more complete solution as needed.
Once a method is tracked, its arguments and returns are available to be used in feedback functions. This is done by using the Select class to select the arguments and returns of the method.
Doing so follows the structure:
For args: Select.RecordCalls.<method_name>.args.<arg_name>
For returns: Select.RecordCalls.<method_name>.rets.<ret_name>
Example: \"Defining feedback functions with instrumented methods\"
```python\nf_context_relevance = (\n Feedback(provider.context_relevance_with_cot_reasons, name = \"Context Relevance\")\n .on(Select.RecordCalls.retrieve_chunks.args.query) # refers to the query arg of CustomApp's retrieve_chunks method\n .on(Select.RecordCalls.retrieve_chunks.rets.collect())\n .aggregate(np.mean)\n )\n```\n
Last, the TruCustomApp recorder can wrap our custom application, and provide logging and evaluation upon its use.
Example: \"Using the TruCustomApp recorder\"
```python\nfrom trulens.apps.custom import TruCustomApp\n\ntru_recorder = TruCustomApp(custom_app,\n app_name=\"Custom Application\",\n app_version=\"base\",\n feedbacks=[f_context_relevance])\n\nwith tru_recorder as recording:\n custom_app.respond_to_query(\"What is the capital of Indonesia?\")\n```\n\nSee [Feedback\nFunctions](https://www.trulens.org/trulens/api/feedback/) for\ninstantiating feedback functions.\n
PARAMETER DESCRIPTION app
Any class.
TYPE: Any
**kwargs
Additional arguments to pass to App and AppDefinition
Computed deterministically from app_name and app_version. Leaving it here for it to be dumped when serializing. Also making it read-only as it should not be changed after creation.
Ideally this would be a ClassVar but since we want to check this without instantiating the subclass of AppDefinition that would define it, we cannot use ClassVar.
Info to store about the app and to display in dashboard.
This can be used even if app itself cannot be serialized. app_extra_json, then, can stand in place for whatever data the user might want to keep track of about the app.
These are checked to make sure the object walk finds them. If not, a message is shown to let user know how to let the TruCustomApp constructor know where these methods are.
Wrap any lazy values in the return value of a method call to invoke handle_done when the value is ready.
This is used to handle library-specific lazy values that are hidden in containers not visible otherwise. Visible lazy values like iterators, generators, awaitables, and async generators are handled elsewhere.
PARAMETER DESCRIPTION rets
The return value of the method call.
TYPE: Any
wrap
A callback to be called when the lazy value is ready. Should return the input value or a wrapped version of it.
TYPE: Callable[[T], T]
on_done
Called when the lazy values is done and is no longer lazy. This as opposed to a lazy value that evaluates to another lazy values. Should return the value or wrapper.
TYPE: Callable[[T], T]
context_vars
The contextvars to be captured by the lazy value. If not given, all contexts are captured.
This is an experimental feature with ongoing work.
Create a copy of the json serialized app with the enclosed app being initialized to its initial state before any records are produced (i.e. blank memory).
Timeout in seconds for waiting for feedback results for each feedback function. Note that this is not the total timeout for this entire blocking call.

RETURNS DESCRIPTION List[Record]
A list of records that have been waited on. Note a record will be included even if a feedback computation for it failed or timed out.
This applies to all feedbacks on all records produced by this app. This call will block until finished and if new records are produced while this is running, it will include them.

Create a dummy record with some of the expected structure without actually invoking the app.
The record is a guess of what an actual record might look like but will be missing information that can only be determined after a call is made.
All args are Record fields except these:
- `record_id` is generated using the default id naming schema.\n- `app_id` is taken from this recorder.\n- `calls` field is constructed based on instrumented methods.\n
This module facilitates the ingestion and evaluation of application logs that were generated outside of TruLens. It allows for the creation of a virtual representation of your application, enabling the evaluation of logged data within the TruLens framework.
To begin, construct a virtual application representation. This can be achieved through a simple dictionary or by utilizing the VirtualApp class, which allows for a more structured approach to storing application information relevant for feedback evaluation.
Example: \"Constructing a Virtual Application\"
```python\nvirtual_app = {\n 'llm': {'modelname': 'some llm component model name'},\n 'template': 'information about the template used in the app',\n 'debug': 'optional fields for additional debugging information'\n}\n# Converting the dictionary to a VirtualApp instance\nfrom trulens.core import Select\nfrom trulens.apps.virtual import VirtualApp\n\nvirtual_app = VirtualApp(virtual_app)\nvirtual_app[Select.RecordCalls.llm.maxtokens] = 1024\n```\n
Incorporate components into the virtual app for evaluation by utilizing the Select class. This approach allows for the reuse of setup configurations when defining feedback functions.
Example: \"Incorporating Components into the Virtual App\"
```python\n# Setting up a virtual app with a retriever component\nfrom trulens.core import Select\nretriever_component = Select.RecordCalls.retriever\nvirtual_app[retriever_component] = 'this is the retriever component'\n```\n
With your virtual app configured, it's ready to store logged data. VirtualRecord offers a structured way to build records from your data for ingestion into TruLens, distinguishing itself from direct Record creation by specifying calls through selectors.
Below is an example of adding records for a context retrieval component, emphasizing that only the data intended for tracking or evaluation needs to be provided.
Example: \"Adding Records for a Context Retrieval Component\"
```python\nfrom trulens.apps.virtual import VirtualRecord\n\n# Selector for the context retrieval component's `get_context` call\ncontext_call = retriever_component.get_context\n\n# Creating virtual records\nrec1 = VirtualRecord(\n main_input='Where is Germany?',\n main_output='Germany is in Europe',\n calls={\n context_call: {\n 'args': ['Where is Germany?'],\n 'rets': ['Germany is a country located in Europe.']\n }\n }\n)\nrec2 = VirtualRecord(\n main_input='Where is Germany?',\n main_output='Poland is in Europe',\n calls={\n context_call: {\n 'args': ['Where is Germany?'],\n 'rets': ['Poland is a country located in Europe.']\n }\n }\n)\n\ndata = [rec1, rec2]\n```\n
For existing datasets, such as a dataframe of prompts, contexts, and responses, iterate through the dataframe to create virtual records for each entry.
Example: \"Creating Virtual Records from a DataFrame\"
```python\nimport pandas as pd\n\n# Example dataframe\ndata = {\n 'prompt': ['Where is Germany?', 'What is the capital of France?'],\n 'response': ['Germany is in Europe', 'The capital of France is Paris'],\n 'context': [\n 'Germany is a country located in Europe.',\n 'France is a country in Europe and its capital is Paris.'\n ]\n}\ndf = pd.DataFrame(data)\n\n# Ingesting data from the dataframe into virtual records\ndata_dict = df.to_dict('records')\ndata = []\n\nfor record in data_dict:\n rec = VirtualRecord(\n main_input=record['prompt'],\n main_output=record['response'],\n calls={\n context_call: {\n 'args': [record['prompt']],\n 'rets': [record['context']]\n }\n }\n )\n data.append(rec)\n```\n
After constructing the virtual records, feedback functions can be developed in the same manner as with non-virtual applications, using the newly added context_call selector for reference.
Example: \"Developing Feedback Functions\"
```python\nfrom trulens.providers.openai import OpenAI\nfrom trulens.core.feedback.feedback import Feedback\n\n# Initializing the feedback provider\nopenai = OpenAI()\n\n# Defining the context for feedback using the virtual `get_context` call\ncontext = context_call.rets[:]\n\n# Creating a feedback function for context relevance\nf_context_relevance = Feedback(openai.context_relevance).on_input().on(context)\n```\n
These feedback functions are then integrated into TruVirtual to construct the recorder, which can handle most configurations applicable to non-virtual apps.
Example: \"Integrating Feedback Functions into TruVirtual\"
```python\nfrom trulens.apps.virtual import TruVirtual\n\n# Setting up the virtual recorder\nvirtual_recorder = TruVirtual(\n app_name='a virtual app',\n app_version='base',\n app=virtual_app,\n feedbacks=[f_context_relevance]\n)\n```\n
To process the records and run any feedback functions associated with the recorder, use the add_record method.
Example: \"Logging records and running feedback functions\"
```python\n# Ingesting records into the virtual recorder\nfor record in data:\n virtual_recorder.add_record(record)\n```\n
Metadata about your application can also be included in the VirtualApp for evaluation purposes, offering a flexible way to store additional information about the components of an LLM app.
Example: \"Storing metadata in a VirtualApp\"
```python\n# Example of storing metadata in a VirtualApp\nvirtual_app = {\n 'llm': {'modelname': 'some llm component model name'},\n 'template': 'information about the template used in the app',\n 'debug': 'optional debugging information'\n}\n\nfrom trulens.core import Select\nfrom trulens.apps.virtual import VirtualApp\n\nvirtual_app = VirtualApp(virtual_app)\nvirtual_app[Select.RecordCalls.llm.maxtokens] = 1024\n```\n
This approach is particularly beneficial for evaluating the components of an LLM app.
Example: \"Evaluating components of an LLM application\"
```python\n# Adding a retriever component to the virtual app\nretriever_component = Select.RecordCalls.retriever\nvirtual_app[retriever_component] = 'this is the retriever component'\n```\n
Many arguments are filled in by default values if not provided. See Record for all arguments. Listing here is only for those which are required for this method or filled with default values.
PARAMETER DESCRIPTION calls
A dictionary of calls to be recorded. The keys are selectors and the values are dictionaries with the keys listed in the next section.
TYPE: Dict[Lens, Union[Dict, Sequence[Dict]]]
cost
Defaults to zero cost.
TYPE: Optional[Cost] DEFAULT: None
perf
Defaults to time spanning the processing of this virtual record. Note that individual calls also include perf. Time span is extended to make sure it is not of duration zero.
TYPE: Optional[Perf] DEFAULT: None
Call values are dictionaries containing arguments to RecordAppCall constructor. Values can also be lists of the same. This happens in non-virtual apps when the same method is recorded making multiple calls in a single app invocation. The following defaults are used if not provided.

Map of feedbacks to the futures for of their results.
These are only filled for records that were just produced. This will not be filled in when read from database. Also, will not fill in when using FeedbackMode.DEFERRED.
Virtual apps are data only in that they cannot be executed but for whom previously-computed results can be added using add_record. The VirtualRecord class may be useful for creating records for this. Fields used by non-virtual apps can be specified here, notably:
See App and AppDefinition for constructor arguments.
You can store any information you would like by passing in a dictionary to TruVirtual in the app field. This may involve an index of components or versions, or anything else. You can refer to these values for evaluating feedback.
Usage
You can use VirtualApp to create the app structure or a plain dictionary. Using VirtualApp lets you use Selectors to define components:
virtual_app = dict(\n llm=dict(\n modelname=\"some llm component model name\"\n ),\n template=\"information about the template I used in my app\",\n debug=\"all of these fields are completely optional\"\n)\n\nvirtual = TruVirtual(\n app_name=\"my_virtual_app\",\n app_version=\"base\",\n app=virtual_app\n)\n
Computed deterministically from app_name and app_version. Leaving it here for it to be dumped when serializing. Also making it read-only as it should not be changed after creation.
Info to store about the app and to display in dashboard.
This can be used even if app itself cannot be serialized. app_extra_json, then, can stand in place for whatever data the user might want to keep track of about the app.

This is done so we can be aware when new instances are created and is needed for wrapped methods that dynamically create instances of classes we wish to instrument. As they will not be visible at the time we wrap the app, we need to pay attention to new to make a note of them when they are created and the creator's path. This path will be used to place these new instances in the app json structure.
This recorder is designed for LangChain apps, providing a way to instrument, log, and evaluate their behavior.
Example: \"Creating a LangChain RAG application\"
Consider an example LangChain RAG application. For the complete code\nexample, see [LangChain\nQuickstart](https://www.trulens.org/trulens/getting_started/quickstarts/langchain_quickstart/).\n\n```python\nfrom langchain import hub\nfrom langchain.chat_models import ChatOpenAI\nfrom langchain.schema import StrOutputParser\nfrom langchain_core.runnables import RunnablePassthrough\n\nretriever = vectorstore.as_retriever()\n\nprompt = hub.pull(\"rlm/rag-prompt\")\nllm = ChatOpenAI(model_name=\"gpt-3.5-turbo\", temperature=0)\n\nrag_chain = (\n {\"context\": retriever | format_docs, \"question\": RunnablePassthrough()}\n | prompt\n | llm\n | StrOutputParser()\n)\n```\n
Feedback functions can utilize the specific context produced by the application's retriever. This is achieved using the select_context method, which then can be used by a feedback selector, such as on(context).
Example: \"Defining a feedback function\"
```python\nfrom trulens.providers.openai import OpenAI\nfrom trulens.core import Feedback\nimport numpy as np\n\n# Select context to be used in feedback.\nfrom trulens.apps.langchain import TruChain\ncontext = TruChain.select_context(rag_chain)\n\n\n# Use feedback\nf_context_relevance = (\n Feedback(provider.context_relevance_with_context_reasons)\n .on_input()\n .on(context) # Refers to context defined from `select_context`\n .aggregate(np.mean)\n)\n```\n
The application can be wrapped in a TruChain recorder to provide logging and evaluation upon the application's use.
Example: \"Using the TruChain recorder\"
```python\nfrom trulens.apps.langchain import TruChain\n\n# Wrap application\ntru_recorder = TruChain(\n chain,\n app_name=\"ChatApplication\",\n app_version=\"chain_v1\",\n feedbacks=[f_context_relevance]\n)\n\n# Record application runs\nwith tru_recorder as recording:\n chain(\"What is langchain?\")\n```\n

PARAMETER DESCRIPTION app
A LlamaIndex application.
TYPE: Union[BaseQueryEngine, BaseChatEngine]
**kwargs
Additional arguments to pass to App and AppDefinition.
Computed deterministically from app_name and app_version. Leaving it here for it to be dumped when serializing. Also making it read-only as it should not be changed after creation.
Ideally this would be a ClassVar but since we want to check this without instantiating the subclass of AppDefinition that would define it, we cannot use ClassVar.
Info to store about the app and to display in dashboard.
This can be used even if app itself cannot be serialized. app_extra_json, then, can stand in place for whatever data the user might want to keep track of about the app.
This is an experimental feature with ongoing work.
Create a copy of the json serialized app with the enclosed app being initialized to its initial state before any records are produced (i.e. blank memory).
Timeout in seconds for waiting for feedback results for each feedback function. Note that this is not the total timeout for this entire blocking call.
TYPE: Optional[float] DEFAULT: None
RETURNS DESCRIPTION List[Record]
A list of records that have been waited on. Note a record will be included even if a feedback computation for it failed or timed out.
This applies to all feedbacks on all records produced by this app. This call will block until finished and if new records are produced while this is running, it will include them.
Call the given async func with the given *args and **kwargs while recording, producing func results.
The record of the computation is available through other means like the database or dashboard. If you need a record of this execution immediately, you can use awith_record or the App as a context manager instead.

\"Using TruLens guardrail context filters with Llama-Index\"
from trulens.apps.llamaindex.guardrails import WithFeedbackFilterNodes\n\n# note: feedback function used for guardrail must only return a score, not also reasons\nfeedback = (\n Feedback(provider.context_relevance)\n .on_input()\n .on(context)\n)\n\nfiltered_query_engine = WithFeedbackFilterNodes(query_engine, feedback=feedback, threshold=0.5)\n\ntru_recorder = TruLlama(filtered_query_engine,\n app_name=\"LlamaIndex_App\",\n app_version=\"v1_filtered\"\n)\n\nwith tru_recorder as recording:\n llm_response = filtered_query_engine.query(\"What did the author do growing up?\")\n
This is done so we can be aware when new instances are created and is needed for wrapped methods that dynamically create instances of classes we wish to instrument. As they will not be visible at the time we wrap the app, we need to pay attention to new to make a note of them when they are created and the creator's path. This path will be used to place these new instances in the app json structure.
This recorder is designed for LlamaIndex apps, providing a way to instrument, log, and evaluate their behavior.
Example: \"Creating a LlamaIndex application\"
Consider an example LlamaIndex application. For the complete code\nexample, see [LlamaIndex\nQuickstart](https://docs.llamaindex.ai/en/stable/getting_started/starter_example.html).\n\n```python\nfrom llama_index.core import VectorStoreIndex, SimpleDirectoryReader\n\ndocuments = SimpleDirectoryReader(\"data\").load_data()\nindex = VectorStoreIndex.from_documents(documents)\n\nquery_engine = index.as_query_engine()\n```\n
Feedback functions can utilize the specific context produced by the application's retriever. This is achieved using the select_context method, which then can be used by a feedback selector, such as on(context).
Example: \"Defining a feedback function\"
```python\nfrom trulens.providers.openai import OpenAI\nfrom trulens.core import Feedback\nimport numpy as np\n\n# Select context to be used in feedback.\nfrom trulens.apps.llamaindex import TruLlama\ncontext = TruLlama.select_context(query_engine)\n\n# Use feedback\nf_context_relevance = (\n Feedback(provider.context_relevance_with_context_reasons)\n .on_input()\n .on(context) # Refers to context defined from `select_context`\n .aggregate(np.mean)\n)\n```\n
The application can be wrapped in a TruLlama recorder to provide logging and evaluation upon the application's use.
Example: \"Using the TruLlama recorder\"
```python\nfrom trulens.apps.llamaindex import TruLlama\n# f_lang_match, f_qa_relevance, f_context_relevance are feedback functions\ntru_recorder = TruLlama(query_engine,\n app_name='LlamaIndex\",\n app_version=\"base',\n feedbacks=[f_lang_match, f_qa_relevance, f_context_relevance])\n\nwith tru_recorder as recording:\n query_engine.query(\"What is llama index?\")\n```\n

Selector shorthands for NeMo Guardrails apps when used for evaluating feedback in actions.
These should not be used for feedback functions given to TruRails but instead for selectors in the FeedbackActions action invoked from with a rails app.
To use this action, it needs to be registered with your rails app and feedback functions themselves need to be registered with this function. The name under which this action is registered for rails is feedback.
Usage
rails: LLMRails = ... # your app\nlanguage_match: Feedback = Feedback(...) # your feedback function\n\n# First we register some feedback functions with the custom action:\nFeedbackAction.register_feedback_functions(language_match)\n\n# Can also use kwargs expansion from dict like produced by rag_triad:\n# FeedbackAction.register_feedback_functions(**rag_triad(...))\n\n# Then the feedback method needs to be registered with the rails app:\nrails.register_action(FeedbackAction.feedback)\n

Add a single feedback result or future to the database and return its unique id.
PARAMETER DESCRIPTION feedback_result_or_future

If a Future is given, call will wait for the result before adding it to the database. If kwargs are given and a FeedbackResult is also given, the kwargs will be used to update the FeedbackResult otherwise a new one will be created with kwargs as arguments to its constructor.
Typical usage is to specify a feedback implementation function from a Provider and the mapping of selectors describing how to construct the arguments to the implementation:
Example
from trulens.core import Feedback\nfrom trulens.providers.huggingface import Huggingface\nhugs = Huggingface()\n\n# Create a feedback function from a provider:\nfeedback = Feedback(\n hugs.language_match # the implementation\n).on_input_output() # selectors shorthand\n
Only execute the feedback function if the following selector names something that exists in a record/app.
Can use this to evaluate conditionally on presence of some calls, for example. Feedbacks skipped this way will have a status of FeedbackResultStatus.SKIPPED.
Specifies that one argument feedbacks should be evaluated on the main app output and two argument feedbacks should be evaluates on main input and main output in that order.
Returns a new Feedback object with this specification.
Evaluates feedback functions that were specified to be deferred.
Returns a list of tuples with the DB row containing the Feedback and initial FeedbackResult as well as the Future which will contain the actual result.
PARAMETER DESCRIPTION limit
The maximum number of evals to start.
TYPE: Optional[int] DEFAULT: None
shuffle

TYPE: bool DEFAULT: False
run_location

TYPE: Optional[FeedbackRunLocation] DEFAULT: None
Constants that govern behavior:
TruSession.RETRY_RUNNING_SECONDS: How long to time before restarting a feedback that was started but never failed (or failed without recording that fact).
TruSession.RETRY_FAILED_SECONDS: How long to wait to retry a failed feedback.
Specify the aggregation function in case the selectors for this feedback generate more than one value for implementation argument(s). Can also specify the method of producing combinations of values in such cases.
Returns a new Feedback object with the given aggregation function and/or the given combination mode.
Create a variant of self with the same implementation but the given selectors. Those provided positionally get their implementation argument name guessed and those provided as kwargs get their name from the kwargs key.
Check that the selectors are valid for the given app and record.
PARAMETER DESCRIPTION app
The app that produced the record.
TYPE: Union[AppDefinition, JSON]
record
The record that the feedback will run on. This can be a mostly empty record for checking ahead of producing one. The utility method App.dummy_record is built for this purpose.
TYPE: Record
source_data
Additional data to select from when extracting feedback function arguments.
TYPE: Optional[Dict[str, Any]] DEFAULT: None
warning
Issue a warning instead of raising an error if a selector is invalid. As some parts of a Record cannot be known ahead of producing it, it may be necessary to not raise exception here and only issue a warning.
TYPE: bool DEFAULT: False
RETURNS DESCRIPTION bool
True if the selectors are valid. False if not (if warning is set).
Given the app that produced the given record, extract from record the values that will be sent as arguments to the implementation as specified by self.selectors. Additional data to select from can be provided in source_data. All args are optional. If a Record is specified, its calls are laid out as app (see layout_calls_as_app).
TruLens makes use of Feedback Providers to generate evaluations of large language model applications. These providers act as an access point to different models, most commonly classification models and large language models.
These models are then used to generate feedback on application outputs or intermediate results.
Provider is the base class for all feedback providers. It is an abstract class and should not be instantiated directly. Rather, it should be subclassed and the subclass should implement the methods defined in this class.
There are many feedback providers available in TruLens that grant access to a wide range of proprietary and open-source models.
Providers for classification and other non-LLM models should directly subclass Provider. The feedback functions available for these providers are tied to specific providers, as they rely on provider-specific endpoints to models that are tuned to a particular task.
For example, the Huggingface feedback provider provides access to a number of classification models for specific tasks, such as language detection. These models are than utilized by a feedback function to generate an evaluation score.
Example
from trulens.providers.huggingface import Huggingface\nhuggingface_provider = Huggingface()\nhuggingface_provider.language_match(prompt, response)\n
Providers for LLM models should subclass trulens.feedback.LLMProvider, which itself subclasses Provider. Providers for LLM-generated feedback are more of a plug-and-play variety. This means that the base model of your choice can be combined with feedback-specific prompting to generate feedback.
For example, relevance can be run with any base LLM feedback provider. Once the feedback provider is instantiated with a base model, the relevance function can be called with a prompt and response.
This means that the base model selected is combined with specific prompting for relevance to generate feedback.
Example
from trulens.providers.openai import OpenAI\nprovider = OpenAI(model_engine=\"gpt-3.5-turbo\")\nprovider.relevance(prompt, response)\n
Only execute the feedback function if the following selector names something that exists in a record/app.

TruLlama: Llama Index apps.
TruRails: NeMo Guardrails apps.
TruBasicApp: Basic apps defined solely using a function from str to str.
TruCustomApp: Custom apps containing custom structures and methods. Requires annotation of methods to instrument.

PARAMETER DESCRIPTION feedback_result_or_future
If a Future is given, call will wait for the result before adding it to the database. If kwargs are given and a FeedbackResult is also given, the kwargs will be used to update the FeedbackResult otherwise a new one will be created with kwargs as arguments to its constructor.
Create a new dataset, if not existing, and add ground truth data to it. If the dataset with the same name already exists, the ground truth data will be added to it.
Views of common app component types for sorting them and displaying them in some unified manner in the UI. Operates on components serialized into json dicts representing various components, not the components themselves.
Given a sequence of classes, return the first one which comes from one of the among_modules. You can use this to determine where ultimately the encoded class comes from in terms of langchain, llama_index, or trulens even in cases they extend each other's classes. Returns None if no module from among_modules is named in bases.

Non-serialized fields here while the serialized ones are defined in AppDefinition.
This class is abstract. Use one of these concrete subclasses as appropriate: - TruLlama for LlamaIndex apps. - TruChain for LangChain apps. - TruRails for NeMo Guardrails apps. - TruVirtual for recording information about invocations of apps without access to those apps. - TruCustomApp for custom apps. These need to be decorated to have appropriate data recorded. - TruBasicApp for apps defined solely by a string-to-string method.
Computed deterministically from app_name and app_version. Leaving it here for it to be dumped when serializing. Also making it read-only as it should not be changed after creation.
Ideally this would be a ClassVar but since we want to check this without instantiating the subclass of AppDefinition that would define it, we cannot use ClassVar.

PARAMETER DESCRIPTION rets
The return value of the method call.
TYPE: Any
wrap
A callback to be called when the lazy value is ready. Should return the input value or a wrapped version of it.
TYPE: Callable[[T], T]
on_done
Called when the lazy values is done and is no longer lazy. This as opposed to a lazy value that evaluates to another lazy values. Should return the value or wrapper.
TYPE: Callable[[T], T]
context_vars
The contextvars to be captured by the lazy value. If not given, all contexts are captured.
This is an experimental feature with ongoing work.
Create a copy of the json serialized app with the enclosed app being initialized to its initial state before any records are produced (i.e. blank memory).
Timeout in seconds for waiting for feedback results for each feedback function. Note that this is not the total timeout for this entire blocking call.
TYPE: Optional[float] DEFAULT: None
RETURNS DESCRIPTION List[Record]
A list of records that have been waited on. Note a record will be included even if a feedback computation for it failed or timed out.
This applies to all feedbacks on all records produced by this app. This call will block until finished and if new records are produced while this is running, it will include them.
Try to find retriever components in the given app and return a lens to access the retrieved contexts that would appear in a record were these components to execute.
Call the given async func with the given *args and **kwargs while recording, producing func results.
The record of the computation is available through other means like the database or dashboard. If you need a record of this execution immediately, you can use awith_record or the App as a context manager instead.

The record of the computation is available through other means like the database or dashboard. If you need a record of this execution immediately, you can use awith_record or the App as a context manager instead.
dummy_record(\n cost: Cost = mod_base_schema.Cost(),\n perf: Perf = mod_base_schema.Perf.now(),\n ts: datetime = datetime.datetime.now(),\n main_input: str = \"main_input are strings.\",\n main_output: str = \"main_output are strings.\",\n main_error: str = \"main_error are strings.\",\n meta: Dict = {\"metakey\": \"meta are dicts\"},\n tags: str = \"tags are strings\",\n) -> Record\n
Create a dummy record with some of the expected structure without actually invoking the app.
The record is a guess of what an actual record might look like but will be missing information that can only be determined after a call is made.
All args are Record fields except these:
- `record_id` is generated using the default id naming schema.\n- `app_id` is taken from this recorder.\n- `calls` field is constructed based on instrumented methods.\n
Iterate over contents of obj that are annotated with the CLASS_INFO attribute/key. Returns triples with the accessor/selector, the Class object instantiated from CLASS_INFO, and the annotated object itself.
This module contains the core of the app instrumentation scheme employed by trulens to track and record apps. These details should not be relevant for typical use cases.
Callback to be called by instrumentation system for every function requested to be instrumented.
Given are the object of the class in which func belongs (i.e. the \"self\" for that function), the func itself, and the path of the owner object in the app hierarchy.
PARAMETER DESCRIPTION obj
The object of the class in which func belongs (i.e. the \"self\" for that method).
TYPE: object
func
The function that was instrumented. Expects the unbound version (self not yet bound).
TYPE: Callable
path
The path of the owner object in the app hierarchy.
Wrap any lazy values in the return value of a method call to invoke handle_done when the value is ready.
This is used to handle library-specific lazy values that are hidden in containers not visible otherwise. Visible lazy values like iterators, generators, awaitables, and async generators are handled elsewhere.

TYPE: Callable[[T], T]
on_done
Called when the lazy values is done and is no longer lazy. This as opposed to a lazy value that evaluates to another lazy values. Should return the value or wrapper.
TYPE: Callable[[T], T]
context_vars
The contextvars to be captured by the lazy value. If not given, all contexts are captured.
Called by instrumented methods in cases where they cannot find a record call list in the stack. If we are inside a context manager, return a new call list.
This is done so we can be aware when new instances are created and is needed for wrapped methods that dynamically create instances of classes we wish to instrument. As they will not be visible at the time we wrap the app, we need to pay attention to new to make a note of them when they are created and the creator's path. This path will be used to place these new instances in the app json structure.
Check whether given object matches a class-based filter.
A class-based filter here means either a type to match against object (isinstance if object is not a type or issubclass if object is a type), or a tuple of types to match against interpreted disjunctively.
PARAMETER DESCRIPTION f
The filter to match against.
TYPE: ClassFilter
obj
The object to match against. If type, uses issubclass to match. If object, uses isinstance to match against filters of Type or Tuple[Type].
TruSession is the main class that provides an entry points to trulens.
TruSession lets you:
Log app prompts and outputs
Log app Metadata
Run and log feedback functions
Run streamlit dashboard to view experiment results
By default, all data is logged to the current working directory to \"default.sqlite\". Data can be logged to a SQLAlchemy-compatible url referred to by database_url.
Supported App Types
TruChain: Langchain apps.
TruLlama: Llama Index apps.
TruRails: NeMo Guardrails apps.
TruBasicApp: Basic apps defined solely using a function from str to str.
TruCustomApp: Custom apps containing custom structures and methods. Requires annotation of methods to instrument.
TruVirtual: Virtual apps that do not have a real app to instrument but have a virtual structure and can log existing captured data as if they were trulens records.
PARAMETER DESCRIPTION connector
Database Connector to use. If not provided, a default DefaultDBConnector is created.
TYPE: Optional[DBConnector] DEFAULT: None
experimental_feature_flags
Experimental feature flags. See ExperimentalSettings.
Add a single feedback result or future to the database and return its unique id.
PARAMETER DESCRIPTION feedback_result_or_future
If a Future is given, call will wait for the result before adding it to the database. If kwargs are given and a FeedbackResult is also given, the kwargs will be used to update the FeedbackResult otherwise a new one will be created with kwargs as arguments to its constructor.
Create a new dataset, if not existing, and add ground truth data to it. If the dataset with the same name already exists, the ground truth data will be added to it.
Migrate the stored data to the current configuration of the database.
PARAMETER DESCRIPTION prior_prefix
If given, the database is assumed to have been reconfigured from a database with the given prefix. If not given, it may be guessed if there is only one table in the database with the suffix alembic_version.
ORM base class except with __tablename__ defined in terms of a base name and a prefix.
A subclass should set _table_base_name and/or _table_prefix. If it does not set both, make sure to set __abstract__ = True. Current design has subclasses set _table_base_name and then subclasses of that subclass setting _table_prefix as in make_orm_for_prefix.
Note: This is a function to be able to define classes extending different SQLAlchemy declarative bases. Each different such bases has a different set of mappings from classes to table names. If we only had one of these, our code will never be able to have two different sets of mappings at the same time. We need to be able to have multiple mappings for performing things such as database migrations and database copying from one database configuration to another.
Create a database for the given engine. Args: engine: The database engine. kwargs: Additional arguments to pass to the database constructor. Returns: A database instance.
Copy all data from a source database to an EMPTY target database.
Important considerations:
All source data will be appended to the target tables, so it is important that the target database is empty.
Will fail if the databases are not at the latest schema revision. That can be fixed with TruSession(database_url=\"...\", database_prefix=\"...\").migrate_database()
Might fail if the target database enforces relationship constraints, because then the order of inserting data matters.
This process is NOT transactional, so it is highly recommended that the databases are NOT used by anyone while this process runs.
Add a single feedback result or future to the database and return its unique id.
PARAMETER DESCRIPTION feedback_result_or_future
If a Future is given, call will wait for the result before adding it to the database. If kwargs are given and a FeedbackResult is also given, the kwargs will be used to update the FeedbackResult otherwise a new one will be created with kwargs as arguments to its constructor.

Create a compatibility DB (checkout the last pypi rc branch https://github.com/truera/trulens/tree/releases/rc-trulens-X.x.x/): In trulens/tests/docs_notebooks/notebooks_to_test remove any local dbs
rm rf default.sqlite run below notebooks (Making sure you also run with the same X.x.x version trulens)
The upgrade methodology is determined by this data structure upgrade_paths = { # from_version: (to_version,migrate_function) \"0.1.2\": (\"0.2.0\", migrate_0_1_2), \"0.2.0\": (\"0.3.0\", migrate_0_2_0) }
add your version to the version list: migration_versions: list = [YOUR VERSION HERE,...,\"0.3.0\", \"0.2.0\", \"0.1.2\"]
To Test
replace your db file with an old version db first and see if the session.migrate_database() works.
Add a DB file for testing new breaking changes (Same as step 1: but with your new version)
Do a sys.path.insert(0,TRULENS_PATH) to run with your version
When upgrading TruLens, it may sometimes be required to migrate the database to incorporate changes in existing database created from the previously installed version. The changes to database schemas is handled by Alembic while some data changes are handled by converters in the data module.

Since 0.28.0, all tables used by TruLens are prefixed with \"trulens_\" including the special alembic_version table used for tracking schema changes. Upgrading to 0.28.0 for the first time will require a migration as specified above. This migration assumes that the prefix in the existing database was blank.
If you need to change this prefix after migration, you may need to specify the old prefix when invoking migrate_database:

Copy all data from the source database into an EMPTY target database:
from trulens.core.database.utils import copy_database\n\ncopy_database(\n src_url=\"<source_db_url>\",\n tgt_url=\"<target_db_url>\",\n src_prefix=\"<source_db_prefix>\",\n tgt_prefix=\"<target_db_prefix>\"\n)\n
This configures the context with just a URL and not an Engine, though an Engine is acceptable here as well. By skipping the Engine creation we don't even need a DBAPI to be available.
Calls to context.execute() here emit the given string to the script output.
Also note that Endpoints are singletons (one for each unique name argument) hence this global callback will track all requests for the named api even if you try to create multiple endpoints (with the same name).
Track costs of all of the apis we can currently track, over the execution of thunk.
RETURNS DESCRIPTION T
Result of evaluating the thunk.
TYPE: T
Thunk[Cost]
Thunk[Cost]: A thunk that returns the total cost of all callbacks that tracked costs. This is a thunk as the costs might change after this method returns in case of Awaitable results.
Typical usage is to specify a feedback implementation function from a Provider and the mapping of selectors describing how to construct the arguments to the implementation:
Example
from trulens.core import Feedback\nfrom trulens.providers.huggingface import Huggingface\nhugs = Huggingface()\n\n# Create a feedback function from a provider:\nfeedback = Feedback(\n hugs.language_match # the implementation\n).on_input_output() # selectors shorthand\n
Only execute the feedback function if the following selector names something that exists in a record/app.
Can use this to evaluate conditionally on presence of some calls, for example. Feedbacks skipped this way will have a status of FeedbackResultStatus.SKIPPED.
Specifies that one argument feedbacks should be evaluated on the main app output and two argument feedbacks should be evaluates on main input and main output in that order.
Returns a new Feedback object with this specification.

TruLens makes use of Feedback Providers to generate evaluations of large language model applications. These providers act as an access point to different models, most commonly classification models and large language models.
These models are then used to generate feedback on application outputs or intermediate results.
Provider is the base class for all feedback providers. It is an abstract class and should not be instantiated directly. Rather, it should be subclassed and the subclass should implement the methods defined in this class.
There are many feedback providers available in TruLens that grant access to a wide range of proprietary and open-source models.
Providers for classification and other non-LLM models should directly subclass Provider. The feedback functions available for these providers are tied to specific providers, as they rely on provider-specific endpoints to models that are tuned to a particular task.
For example, the Huggingface feedback provider provides access to a number of classification models for specific tasks, such as language detection. These models are than utilized by a feedback function to generate an evaluation score.
Example
from trulens.providers.huggingface import Huggingface\nhuggingface_provider = Huggingface()\nhuggingface_provider.language_match(prompt, response)\n
Providers for LLM models should subclass trulens.feedback.LLMProvider, which itself subclasses Provider. Providers for LLM-generated feedback are more of a plug-and-play variety. This means that the base model of your choice can be combined with feedback-specific prompting to generate feedback.
For example, relevance can be run with any base LLM feedback provider. Once the feedback provider is instantiated with a base model, the relevance function can be called with a prompt and response.
This means that the base model selected is combined with specific prompting for relevance to generate feedback.
Example
from trulens.providers.openai import OpenAI\nprovider = OpenAI(model_engine=\"gpt-3.5-turbo\")\nprovider.relevance(prompt, response)\n

Many of the classes defined here extending serial.SerialModel are meant to be serialized into json. Most are extended with non-serialized fields in other files.
AppDefinition.app is the JSON-ized version of a wrapped app while App.app is the actual wrapped app. We can thus inspect the contents of a wrapped app without having to construct it. Additionally, JSONized objects like AppDefinition.app feature information about the encoded object types in the dictionary under the util.py:CLASS_INFO key.
Computed deterministically from app_name and app_version. Leaving it here for it to be dumped when serializing. Also making it read-only as it should not be changed after creation.

Info to store about the app and to display in dashboard.
This can be used even if app itself cannot be serialized. app_extra_json, then, can stand in place for whatever data the user might want to keep track of about the app.

Specify this using the feedback_mode to App constructors.
Note
This class extends str to allow users to compare its values with their string representations, i.e. in if mode == \"none\": .... Internal uses should use the enum instances.
This might involve multiple feedback function calls. Typically you should not be constructing these objects yourself except for the cases where you'd like to log human feedback.

Create a copy of the json serialized app with the enclosed app being initialized to its initial state before any records are produced (i.e. blank memory).
Specify this using the feedback_mode to App constructors.
Note
This class extends str to allow users to compare its values with their string representations, i.e. in if mode == \"none\": .... Internal uses should use the enum instances.
For deferred feedback evaluation, these values indicate status of evaluation.
Note
This class extends str to allow users to compare its values with their string representations, i.e. in if status == \"done\": .... Internal uses should use the enum instances.
This can be because because it had an if_exists selector and did not select anything or it has a selector that did not select anything the on_missing was set to warn or ignore.
How to handle missing parameters in feedback function calls.
This is specifically for the case were a feedback function has a selector that selects something that does not exist in a record/app.
Note
This class extends str to allow users to compare its values with their string representations, i.e. in if onmissing == \"error\": .... Internal uses should use the enum instances.
This might involve multiple feedback function calls. Typically you should not be constructing these objects yourself except for the cases where you'd like to log human feedback.

How to collect arguments for feedback function calls.
Note that this applies only to cases where selectors pick out more than one thing for feedback function arguments. This option is used for the field combinations of FeedbackDefinition and can be specified with Feedback.aggregate.
Match argument values per position in produced values.
Example
If the selector for arg1 generates values 0, 1, 2 and one for arg2 generates values \"a\", \"b\", \"c\", the feedback function will be called 3 times with kwargs:
{'arg1': 0, arg2: \"a\"},
{'arg1': 1, arg2: \"b\"},
{'arg1': 2, arg2: \"c\"}
If the quantities of items in the various generators do not match, the result will have only as many combinations as the generator with the fewest items as per python zip (strict mode is not used).
Note that selectors can use Lens collect() to name a single (list) value instead of multiple values.
Evaluate feedback on all combinations of feedback function arguments.
Example
If the selector for arg1 generates values 0, 1 and the one for arg2 generates values \"a\", \"b\", the feedback function will be called 4 times with kwargs:
{'arg1': 0, arg2: \"a\"},
{'arg1': 0, arg2: \"b\"},
{'arg1': 1, arg2: \"a\"},
{'arg1': 1, arg2: \"b\"}
See itertools.product for more.
Note that selectors can use Lens collect() to name a single (list) value instead of multiple values.
Only execute the feedback function if the following selector names something that exists in a record/app.
Can use this to evaluate conditionally on presence of some calls, for example. Feedbacks skipped this way will have a status of FeedbackResultStatus.SKIPPED.
This is shared across different instances of RecordAppCall if they refer to the same python method call. This may happen if multiple recorders capture the call in which case they will each have a different RecordAppCall but the call_id will be the same.
Map of feedbacks to the futures for of their results.
These are only filled for records that were just produced. This will not be filled in when read from database. Also, will not fill in when using FeedbackMode.DEFERRED.
NOTE: we cannot name a module \"async\" as it is a python keyword.
"},{"location":"reference/trulens/core/utils/asynchro/#trulens.core.utils.asynchro--synchronous-vs-asynchronous","title":"Synchronous vs. Asynchronous","text":"
Some functions in TruLens come with asynchronous versions. Those use \"async def\" instead of \"def\" and typically start with the letter \"a\" in their name with the rest matching their synchronous version.
Due to how python handles such functions and how they are executed, it is relatively difficult to reshare code between the two versions. Asynchronous functions are executed by an async loop (see EventLoop). Python prevents any threads from having more than one running loop meaning one may not be able to create one to run some async code if one has already been created/running in the thread. The method sync here, used to convert an async computation into a sync computation, needs to create a new thread. The impact of this, whether overhead, or record info, is uncertain.
"},{"location":"reference/trulens/core/utils/asynchro/#trulens.core.utils.asynchro--what-should-be-syncasync","title":"What should be Sync/Async?","text":"
Try to have all internals be async but for users we may expose sync versions via the sync method. If internals are async and don't need exposure, don't need to provide a synced version.
Run the given function asynchronously with the given args. If it is not asynchronous, will run in thread. Note: this has to be marked async since in some cases we cannot tell ahead of time that func is asynchronous so we may end up running it to produce a coroutine object which we then need to run asynchronously.
Override module's __getattr__ to issue a deprecation errors when looking up attributes.
This expects deprecated names to be prefixed with DEP_ followed by their original pre-deprecation name.
Example
Before deprecationAfter deprecation
# issue module import warning:\npackage_dep_warn()\n\n# define temporary implementations of to-be-deprecated attributes:\nsomething = ... actual working implementation or alias\n
# define deprecated attribute with None/any value but name with \"DEP_\"\n# prefix:\nDEP_something = None\n\n# issue module deprecation warning and override __getattr__ to issue\n# deprecation errors for the above:\nmodule_getattr_override()\n
Also issues a deprecation warning for the module itself. This will be used in the next deprecation stage for throwing errors after deprecation errors.
Issue a deprecation warning for a backwards-compatibility modules.
This is specifically for the trulens_eval -> trulens module renaming and reorganization. If message is given, that is included first in the deprecation warning.
Class to pretend to be a module or some other imported object.
Will raise an error if accessed in some dynamic way. Accesses that are \"static-ish\" will try not to raise the exception so things like defining subclasses of a missing class should not raise exception. Dynamic uses are things like calls, use in expressions. Looking up an attribute is static-ish so we don't throw the error at that point but instead make more dummies.
Warning
While dummies can be used as types, they return false to all isinstance and issubclass checks. Further, the use of a dummy in subclassing produces unreliable results with some of the debugging information such as original_exception may be inaccassible.
This is to make sure that if something optional gets imported as a dummy and is a class to be instrumented, it will not automatically make the instrumentation class check succeed on all objects.
Helper context manager for doing multiple imports from an optional modules
Example
messages = ImportErrorMessages(\n module_not_found=\"install llama_index first\",\n import_error=\"install llama_index==0.1.0\"\n )\n with OptionalImports(messages=messages):\n import llama_index\n from llama_index import query_engine\n
The above python block will not raise any errors but once anything else about llama_index or query_engine gets accessed, an error is raised with the specified message (unless llama_index is installed of course).
Handle exiting from the WithOptionalImports context block.
We should not get any exceptions here if dummies were produced by the overwritten import but if an import of a module that exists failed becomes some component of that module did not, we will not be able to catch it to produce dummy and have to process the exception here in which case we add our informative message to the exception and re-raise it.
Get the path to a static resource file in the trulens package.
By static here we mean something that exists in the filesystem already and not in some temporary folder. We use the importlib.resources context managers to get this but if the resource is temporary, the result might not exist by the time we return or is not expected to survive long.
Check required and optional package versions. Args: ignore_version_mismatch: If set, will not raise an error if a version mismatch is found in a required package. Regardless of this setting, mismatch in an optional package is a warning. Raises: VersionConflict: If a version mismatch is found in a required package and ignore_version_mismatch is not set.
Format two messages for missing optional package or bad import from an optional package.
Throws an ImportError with the formatted message if throw flag is set. If throw is already an exception, throws that instead after printing the message.
Convert the given object into types that can be serialized in json.
Args:\n obj: the object to jsonify.\n\n dicted: the mapping from addresses of already jsonifed objects (via id)\n to their json.\n\n instrument: instrumentation functions for checking whether to recur into\n components of `obj`.\n\n skip_specials: remove specially keyed structures from the json. These\n have keys that start with \"__tru_\".\n\n redact_keys: redact secrets from the output. Secrets are detremined by\n `keys.py:redact_value` .\n\n include_excluded: include fields that are annotated to be excluded by\n pydantic.\n\n depth: the depth of the serialization of the given object relative to\n the serialization of its container.\n
max_depth: the maximum depth of the serialization of the given object. Objects to be serialized beyond this will be serialized as \"non-serialized object\" as pernoserio`. Note that this may happen for some data layouts like linked lists. This value should be no larger than half the value set by sys.setrecursionlimit.
Returns:\n The jsonified version of the given object. Jsonified means that the the\n object is either a JSON base type, a list, or a dict with the containing\n elements of the same.\n

To check whether appropriate api keys have been set:
from trulens.core.utils.keys import check_keys\n\ncheck_keys(\n \"OPENAI_API_KEY\",\n \"HUGGINGFACE_API_KEY\"\n)\n
Alternatively you can set using check_or_set_keys:
from trulens.core.utils.keys import check_or_set_keys\n\ncheck_or_set_keys(\n OPENAI_API_KEY=\"to fill in\",\n HUGGINGFACE_API_KEY=\"to fill in\"\n)\n
This line checks that you have the requisite api keys set before continuing the notebook. They do not need to be provided, however, right on this line. There are several ways to make sure this check passes:
Explicit -- Explicitly provide key values to check_keys.
Python -- Define variables before this check like this:
OPENAI_API_KEY=\"something\"\n
Environment -- Set them in your environment variable. They should be visible when you execute:
import os\nprint(os.environ)\n
.env -- Set them in a .env file in the same folder as the example notebook or one of its parent folders. An example of a .env file is found in trulens/trulens/env.example .
Endpoint class For some keys, set them as arguments to trulens endpoint class that manages the endpoint. For example, with openai, do this ahead of the check_keys check:
from trulens.providers.openai import OpenAIEndpoint\nopenai_endpoint = OpenAIEndpoint(api_key=\"something\")\n
Provider class For some keys, set them as arguments to trulens feedback collection (\"provider\") class that makes use of the relevant endpoint. For example, with openai, do this ahead of the check_keys check:
from trulens.providers.openai import OpenAI\nopenai_feedbacks = OpenAI(api_key=\"something\")\n
In the last two cases, please note that the settings are global. Even if you create multiple OpenAI or OpenAIEndpoint objects, they will share the configuration of keys (and other openai attributes).

Some providers may require additional configuration attributes beyond api key. For example, openai usage via azure require special keys. To set those, you should use the 3rd party class method of configuration. For example with openai:
import openai\n\nopenai.api_type = \"azure\"\nopenai.api_key = \"...\"\nopenai.api_base = \"https://example-endpoint.openai.azure.com\"\nopenai.api_version = \"2023-05-15\" # subject to change\n# See https://learn.microsoft.com/en-us/azure/cognitive-services/openai/how-to/switching-endpoints .\n
Our example notebooks will only check that the api_key is set but will make use of the configured openai object as needed to compute feedback.
Determine whether the given value v should be redacted and redact it if so. If its key k (in a dict/json-like) is given, uses the key name to determine whether redaction is appropriate. If key k is not given, only redacts if v is a string and identical to one of the keys ingested using setup_keys.
Check that all keys named in *args are set as env vars. Will fail with a message on how to set missing key if one is missing. If all are provided somewhere, they will be set in the env var as the canonical location where we should expect them subsequently.
Example
from trulens.core.utils.keys import check_keys\n\ncheck_keys(\n \"OPENAI_API_KEY\",\n \"HUGGINGFACE_API_KEY\"\n)\n
Check various sources of api configuration values like secret keys and set env variables for each of them. We use env variables as the canonical storage of these keys, regardless of how they were specified. Values can also be specified explicitly to this method. Example:
from trulens.core.utils.keys import check_or_set_keys\n\ncheck_or_set_keys(\n OPENAI_API_KEY=\"to fill in\",\n HUGGINGFACE_API_KEY=\"to fill in\"\n)\n
Calls to Pace.mark may block until the pace of its returns is kept to a constraint: the number of returns in the given period of time cannot exceed marks_per_second * seconds_per_period. This means the average number of returns in that period is bounded above exactly by marks_per_second.
Assumes that prior to construction of this Pace instance, the period did not have any marks called. The longer this period is, the bigger burst of marks will be allowed initially and after long periods of no marks.
Return in appropriate pace. Blocks until return can happen in the appropriate pace. Returns time in seconds since last mark returned.

Bases: SerialModel
A python class. Should be enough to deserialize the constructor. Also includes bases so that we can query subtyping relationships without deserializing the class first.
An object that may or may not be loadable from its serialized form. Do not use for base types that don't have a class. Loadable if init_bindings is not None.
A python method. A method belongs to some class in some module and must have a pre-bound self object. The location of the method is encoded in obj alongside self. If obj is Obj with init_bindings, this method should be deserializable.
Try to get the attribute k of the given object. This may evaluate some code if the attribute is a property and may fail. In that case, an dict indicating so is returned.
If get_prop is False, will not return contents of properties (will raise ValueException).
Determine which attributes of the given object should be enumerated for storage and/or display in UI. Returns a dict of those attributes and their values.
For enumerating contents of objects that do not support utility classes like pydantic, we use this method to guess what should be enumerated when serializing/displaying.
If include_props is True, will produce attributes which are properties; otherwise those will be excluded.
This is to be able to use weakref.ref on objects like lists which are otherwise not weakly referenceable. The goal of this class is to generalize weakref.ref to work with any object.
This is used for showing \"already created\" warnings. This is intentionally not the frame itself but a rendering of it to avoid maintaining references to frames and all of the things a frame holds onto.
Class for creating singleton instances except there being one instance max, there is one max per different name argument. If name is never given, reverts to normal singleton behavior.
Determine whether the given function is a coroutine function.
Warning
Inspect checkers for async functions do not work on openai clients, perhaps because they use @typing.overload. Because of that, we detect them by checking __wrapped__ attribute instead. Note that the inspect docs suggest they should be able to handle wrapped functions but perhaps they handle different type of wrapping? See https://docs.python.org/3/library/inspect.html#inspect.iscoroutinefunction . Another place they do not work is the decorator langchain uses to mark deprecated functions.

RETURNS DESCRIPTION Tuple[float, Dict]
Tuple[float, str]: A tuple containing a value between 0.0 (no stereotypes assumed) and 1.0 (stereotypes assumed) and a string containing the reasons for the evaluation.
To further explain how the function works under the hood, consider the statement:
\"Hi. I'm here to help. The university of Washington is a public research university. UW's connections to major corporations in Seattle contribute to its reputation as a hub for innovation and technology\"
The function will split the statement into its component sentences:
\"Hi.\"
\"I'm here to help.\"
\"The university of Washington is a public research university.\"
\"UW's connections to major corporations in Seattle contribute to its reputation as a hub for innovation and technology\"
Next, trivial statements are removed, leaving only:
\"The university of Washington is a public research university.\"
\"UW's connections to major corporations in Seattle contribute to its reputation as a hub for innovation and technology\"
The LLM will then process the statement, to assess the groundedness of the statement.
For the sake of this example, the LLM will grade the groundedness of one statement as 10, and the other as 0.
Then, the scores are normalized, and averaged to give a final groundedness score of 0.5.

This evaluates the positive sentiment of either the prompt or response.
Sentiment is currently available to use with OpenAI, HuggingFace or Cohere as the model provider.
The OpenAI sentiment feedback function prompts a Chat Completion model to rate the sentiment from 0 to 10, and then scales the response down to 0-1.
The HuggingFace sentiment feedback function returns a raw score from 0 to 1.
The Cohere sentiment feedback function uses the classification endpoint and a small set of examples stored in feedback_prompts.py to return either a 0 or a 1.
To use this module, you must have the trulens-providers-bedrock package installed.
pip install trulens-providers-bedrock\n
Amazon Bedrock is a fully managed service that makes FMs from leading AI startups and Amazon available via an API, so you can choose from a wide range of FMs to find the model that is best suited for your use case

Uses Huggingface's papluca/xlm-roberta-base-language-detection model. A function that uses language detection on text1 and text2 and calculates the probit difference on the language detected on text1. The function is: 1.0 - (|probit_language_text1(text1) - probit_language_text1(text2))
A measure to track if the source material supports each sentence in the statement using an NLI model.
First the response will be split into statements using a sentence tokenizer.The NLI model will process each statement using a natural language inference model, and will use the entire source.
Uses Huggingface's truera/context_relevance model, a model that uses computes the relevance of a given context to the prompt. The model can be found at https://huggingface.co/truera/context_relevance.

Args: text: A text prompt that may contain a name.
Returns: Tuple[float, str]: A tuple containing a the likelihood that a PII is contained in the input text and a string containing what PII is detected (if any).
Evaluates the hallucination score for a combined input of two statements as a float 0<x<1 representing a true/false boolean. if the return is greater than 0.5 the statement is evaluated as true. if the return is less than 0.5 the statement is evaluated as a hallucination.

To further explain how the function works under the hood, consider the statement:
\"Hi. I'm here to help. The university of Washington is a public research university. UW's connections to major corporations in Seattle contribute to its reputation as a hub for innovation and technology\"
The function will split the statement into its component sentences:
\"Hi.\"
\"I'm here to help.\"
\"The university of Washington is a public research university.\"
\"UW's connections to major corporations in Seattle contribute to its reputation as a hub for innovation and technology\"
Next, trivial statements are removed, leaving only:

RETURNS DESCRIPTION Tuple[float, dict]
Tuple[float, dict]: A tuple containing a value between 0.0 (not grounded) and 1.0 (grounded) and a dictionary containing the reasons for the evaluation.
Also note that Endpoints are singletons (one for each unique name argument) hence this global callback will track all requests for the named api even if you try to create multiple endpoints (with the same name).
This is checked to determine whether cost tracking should come from litellm or from another endpoint which we already have cost tracking for. Otherwise there will be double counting.
Track costs of all of the apis we can currently track, over the execution of thunk.
RETURNS DESCRIPTION T

To further explain how the function works under the hood, consider the statement:
\"Hi. I'm here to help. The university of Washington is a public research university. UW's connections to major corporations in Seattle contribute to its reputation as a hub for innovation and technology\"
The function will split the statement into its component sentences:
\"Hi.\"
\"I'm here to help.\"
\"The university of Washington is a public research university.\"
\"UW's connections to major corporations in Seattle contribute to its reputation as a hub for innovation and technology\"
Next, trivial statements are removed, leaving only:
\"The university of Washington is a public research university.\"
\"UW's connections to major corporations in Seattle contribute to its reputation as a hub for innovation and technology\"
The LLM will then process the statement, to assess the groundedness of the statement.
For the sake of this example, the LLM will grade the groundedness of one statement as 10, and the other as 0.
Then, the scores are normalized, and averaged to give a final groundedness score of 0.5.

This class makes use of langchain's cost tracking for openai models. Changes to the involved classes will need to be adapted here. The important classes are:
"},{"location":"reference/trulens/providers/openai/endpoint/#trulens.providers.openai.endpoint--changes-for-openai-10","title":"Changes for openai 1.0","text":"
Previously we instrumented classes openai.* and their methods create and acreate. Now we instrument classes openai.resources.* and their create methods. We also instrument openai.resources.chat.* and their create. To be determined is the instrumentation of the other classes/modules under openai.resources.
openai methods produce structured data instead of dicts now. langchain expects dicts so we convert them to dicts.
This class allows wrapped clients to be serialized into json. Does not serialize API key though. You can access openai.OpenAI under the client attribute. Any attributes not defined by this wrapper are looked up from the wrapped client so you should be able to use this instance as if it were an openai.OpenAI instance.
Also note that Endpoints are singletons (one for each unique name argument) hence this global callback will track all requests for the named api even if you try to create multiple endpoints (with the same name).
Track costs of all of the apis we can currently track, over the execution of thunk.

To further explain how the function works under the hood, consider the statement:
\"Hi. I'm here to help. The university of Washington is a public research university. UW's connections to major corporations in Seattle contribute to its reputation as a hub for innovation and technology\"
The function will split the statement into its component sentences:
\"Hi.\"
\"I'm here to help.\"
\"The university of Washington is a public research university.\"
\"UW's connections to major corporations in Seattle contribute to its reputation as a hub for innovation and technology\"
Next, trivial statements are removed, leaving only:
\"The university of Washington is a public research university.\"
\"UW's connections to major corporations in Seattle contribute to its reputation as a hub for innovation and technology\"
The LLM will then process the statement, to assess the groundedness of the statement.
For the sake of this example, the LLM will grade the groundedness of one statement as 10, and the other as 0.
Then, the scores are normalized, and averaged to give a final groundedness score of 0.5.

It has always been our goal to make it easy to build trustworthy LLM applications. Since we launched last May, the package has grown up before our eyes, morphing from a hacked-together addition to an existing project (trulens-explain) to a thriving, agnostic standard for tracking and evaluating LLM apps. Along the way, we\u2019ve experienced growing pains and discovered inefficiencies in the way TruLens was built. We\u2019ve also heard that the reasons people use TruLens today are diverse, and many of its use cases do not require its full footprint. Today we\u2019re announcing an extensive re-architecture of TruLens that aims to give developers a stable, modular platform for logging and evaluation they can rely on.

Split off trulens-eval from trulens-explain, and let trulens-eval take over the trulens package name. TruLens-Eval is now renamed to TruLens and sits at the root of the TruLens repo, while TruLens-Explain has been moved to its own repository, and is installable at trulens-explain.

Next, we modularized TruLens into a family of different packages, described below. This change is designed to minimize the overhead required for TruLens developers to use the capabilities they need. For example, you can now install instrumentation packages in production without the additional dependencies required to run the dashboard.
trulens-core holds core abstractions for database operations, app instrumentation, guardrails and evaluation.
trulens-dashboard gives you the required capabilities to run and operate the TruLens dashboard.
trulens-apps- prefixed packages give you tools for interacting with LLM apps built with other frameworks, giving you capabilities including tracing, logging and guardrailing. These include trulens-apps-langchain and trulens-apps-llamaindex which hold our popular TruChain and TruLlama wrappers that seamlessly instrument LangChain and Llama-Index apps.
trulens-feedback gives you access to out of the box feedback functions required for running feedback functions. Feedback function implementations must be combined with a selected provider integration.
trulens-providers- prefixed package describes a set of integrations with other libraries for running feedback functions. Today, we offer an extensive set of integrations that allow you to run feedback functions on top of virtually any LLM. These integrations can be installed as standalone packages, and include: trulens-providers-openai, trulens-providers-huggingface, trulens-providers-litellm, trulens-providers-langchain, trulens-providers-bedrock, trulens-providers-cortex.
trulens-connectors- provide ways to log TruLens traces and evaluations to other databases. In addition to connect to any sqlalchemy database with trulens-core, we've added with trulens-connectors-snowflake tailored specifically to connecting to Snowflake. We plan to add more connectors over time.

Today, we\u2019re releasing trulens, trulens-core, trulens-dashboard, trulens-feedback, trulens-providers packages, trulens-connectors packages and trulens-apps packages at v1.0. We will not make breaking changes in the future without bumping the major version.
The base install of trulens will install trulens-core, trulens-feedback and trulens-dashboard making it easy for developers to try TruLens.
Starting 1.0, the trulens_eval package is being deprecated in favor of trulens and several associated required and optional packages.
Until 2024-10-14, backwards compatibility during the warning period is provided by the new content of the trulens_eval package which provides aliases to the in their new locations. See trulens_eval.
Starting 2024-10-15 until 2025-12-01. Usage of trulens_eval will produce errors indicating deprecation.
Beginning 2024-12-01 Installation of the latest version of trulens_eval will be an error itself with a message that trulens_eval is no longer maintained.
Along with this change, we\u2019ve also included a migration guide for moving to TruLens v1.
Please give us feedback on GitHub by creating issues and starting discussions. You can also chime in on slack.

In TruLens, we have long had the Tru() class, a singleton that sets the logging configuration. Many users and new maintainers have found the purpose and usage of Tru() not as clear as it could be.
In v1, we are renaming Tru to TruSession, to represent a session for logging TruLens traces and evaluations. In addition, we have introduced a more deliberate set of database of connectors that can be passed to TruSession().
You can see how to start a TruLens session logging to a postgres database below:
In v1, we\u2019re also introducing new ways to track experiments with app_name and app_version. These new required arguments replace app_id to give you a more dynamic way to track app versions.
In our suggested workflow, app_name represents an objective you\u2019re building your LLM app to solve. All apps with the same app_name should be directly comparable with each other. Then app_version can be used to track each experiment. This should be changed each time you change your application configuration. To more explicitly track the changes to individual configurations and semantic names for versions - you can still use app metadata and tags!
To bring these changes to life, we've also added new filters to the Leaderboard and Evaluations pages. These filters give you the power to focus in on particular apps and versions, or even slice to apps with a specific tag or metadata.

Feedback functions are the backbone of TruLens, and evaluating unique LLM apps may require new evaluations. We'd love your contribution to extend the feedback functions library so others can benefit!
To add a feedback function for an existing model provider, you can add it to an existing provider module. You can read more about the structure of a feedback function in this guide.
New methods can either take a single text (str) as a parameter or two different texts (str), such as prompt and retrieved context. It should return a float, or a dict of multiple floats. Each output value should be a float on the scale of 0 (worst) to 1 (best).
"},{"location":"trulens/contributing/#add-new-feedback-function-providers","title":"\ud83e\udd1d Add new feedback function providers","text":"
Feedback functions often rely on a model provider, such as OpenAI or HuggingFace. If you need a new model provider to utilize feedback functions for your use case, we'd love if you added a new provider class, e.g. Ollama.
You can do so by creating a new provider module in this folder.
Alternatively, we also appreciate if you open a GitHub Issue if there's a model provider you need!
Most bugs are reported and tracked in the Github Issues Page. We try our best in triaging and tagging these issues:
Issues tagged as bug are confirmed bugs. New contributors may want to start with issues tagged with good first issue. Please feel free to open an issue and/or assign an issue to yourself.
If you have applied TruLens to track and evaluate a unique use-case, we would love your contribution in the form of an example notebook: e.g. Evaluating Pinecone Configuration Choices on Downstream App Performance
All example notebooks are expected to:
Start with a title and description of the example
Include a commented out list of dependencies and their versions, e.g. # !pip install trulens==0.10.0 langchain==0.0.268
Include a linked button to a Google colab version of the notebook

Minimal time/effort-to-value If a user already has an llm app coded in one of the supported libraries, give them some value with the minimal effort beyond that app.
Currently to get going, a user needs to add 4 lines of python:
from trulens.dashboard import run_dashboard # line 1\nfrom trulens.apps.langchain import TruChain # line 2\nwith TruChain(app): # 3\n app.invoke(\"some question\") # doesn't count since they already had this\n\nrun_dashboard() # 4\n
3 of these lines are fixed so only #3 would vary in typical cases. From here they can open the dashboard and inspect the recording of their app's invocation including performance and cost statistics. This means trulens must do quite a bit of haggling under the hood to get that data. This is outlined primarily in the Instrumentation section below.
We collect app components and parameters by walking over its structure and producing a json representation with everything we deem relevant to track. The function jsonify is the root of this process.
Classes inheriting BaseModel come with serialization to/from json in the form of model_dump and model_validate. We do not use the serialization to json part of this capability as a lot of LangChain components are tripped to fail it with a \"will not serialize\" message. However, we use make use of pydantic fields to enumerate components of an object ourselves saving us from having to filter out irrelevant internals that are not declared as fields.
We make use of pydantic's deserialization, however, even for our own internal structures (see schema.py for example).

In addition to collecting app parameters, we also collect:

This allows us to deserialize some objects. Pydantic models can be deserialized once we know their class and fields, for example.
This information is also used to determine component types without having to deserialize them first.
Most if not all LangChain components use pydantic which imposes some restrictions but also provides some utilities. Classes inheriting BaseModel do not allow defining new attributes but existing attributes including those provided by pydantic itself can be overwritten (like dict, for example). Presently, we override methods with instrumented versions.

sys.setprofile (see https://docs.python.org/3/library/sys.html#sys.setprofile)
Might incur much overhead and all calls and other event types get intercepted and result in a callback.
langchain/llama_index callbacks. Each of these packages come with some callback system that lets one get various intermediate app results. The drawbacks is the need to handle different callback systems for each system and potentially missing information not exposed by them.
wrapt package (see https://pypi.org/project/wrapt/)
This is only for wrapping functions or classes to resemble their original but does not help us with wrapping existing methods in langchain, for example. We might be able to use it as part of our own wrapping scheme though.
The instrumented versions of functions/methods record the inputs/outputs and some additional data (see RecordAppCallMethod). As more than one instrumented call may take place as part of a app invocation, they are collected and returned together in the calls field of Record.
Calls can be connected to the components containing the called method via the path field of RecordAppCallMethod. This class also holds information about the instrumented method.
"},{"location":"trulens/contributing/design/#call-data-argumentsreturns","title":"Call Data (Arguments/Returns)","text":"
The arguments to a call and its return are converted to json using the same tools as App Data (see above).
The same method call with the same path may be recorded multiple times in a Record if the method makes use of multiple of its versions in the class hierarchy (i.e. an extended class calls its parents for part of its task). In these circumstances, the method field of RecordAppCallMethod will distinguish the different versions of the method.
Thread-safety -- it is tricky to use global data to keep track of instrumented method calls in presence of multiple threads. For this reason we do not use global data and instead hide instrumenting data in the call stack frames of the instrumentation methods. See get_all_local_in_call_stack.
Generators and Awaitables -- If an instrumented call produces a generator or awaitable, we cannot produce the full record right away. We instead create a record with placeholder values for the yet-to-be produce pieces. We then instrument (i.e. replace them in the returned data) those pieces with (TODO generators) or awaitables that will update the record when they get eventually awaited (or generated).
Threads do not inherit call stacks from their creator. This is a problem due to our reliance on info stored on the stack. Therefore we have a limitation:
Limitation: Threads need to be started using the utility class TP or ThreadPoolExecutor also defined in utils/threading.py in order for instrumented methods called in a thread to be tracked. As we rely on call stack for call instrumentation we need to preserve the stack before a thread start which python does not do.
Similar to threads, code run as part of a asyncio.Task does not inherit the stack of the creator. Our current solution instruments asyncio.new_event_loop to make sure all tasks that get created in async track the stack of their creator. This is done in tru_new_event_loop . The function stack_with_tasks is then used to integrate this information with the normal caller stack when needed. This may cause incompatibility issues when other tools use their own event loops or interfere with this instrumentation in other ways. Note that some async functions that seem to not involve Task do use tasks, such as gather.
Limitation: Tasks must be created via our task_factory as per task_factory_with_stack. This includes tasks created by function such as asyncio.gather. This limitation is not expected to be a problem given our instrumentation except if other tools are used that modify async in some ways.
Threading and async limitations. See Threads and Async .
If the same wrapped sub-app is called multiple times within a single call to the root app, the record of this execution will not be exact with regards to the path to the call information. All call paths will address the last subapp (by order in which it is instrumented). For example, in a sequential app containing two of the same app, call records will be addressed to the second of the (same) apps and contain a list describing calls of both the first and second.
TODO(piotrm): This might have been fixed. Check.
Some apps cannot be serialized/jsonized. Sequential app is an example. This is a limitation of LangChain itself.
Instrumentation relies on CPython specifics, making heavy use of the inspect module which is not expected to work with other Python implementations.
langchain/llama_index callbacks. These provide information about component invocations but the drawbacks are need to cover disparate callback systems and possibly missing information not covered.
Our tracking of calls uses instrumentated versions of methods to manage the recording of inputs/outputs. The instrumented methods must distinguish themselves from invocations of apps that are being tracked from those not being tracked, and of those that are tracked, where in the call stack a instrumented method invocation is. To achieve this, we rely on inspecting the python call stack for specific frames:
Prior frame -- Each instrumented call searches for the topmost instrumented call (except itself) in the stack to check its immediate caller (by immediate we mean only among instrumented methods) which forms the basis of the stack information recorded alongside the inputs/outputs.
Python call stacks are implementation dependent and we do not expect to operate on anything other than CPython.
Python creates a fresh empty stack for each thread. Because of this, we need special handling of each thread created to make sure it keeps a hold of the stack prior to thread creation. Right now we do this in our threading utility class TP but a more complete solution may be the instrumentation of threading.Thread class.
contextvars -- LangChain uses these to manage contexts such as those used for instrumenting/tracking LLM usage. These can be used to manage call stack information like we do. The drawback is that these are not threadsafe or at least need instrumenting thread creation. We have to do a similar thing by requiring threads created by our utility package which does stack management instead of contextvar management.
NOTE(piotrm): it seems to be standard thing to do to copy the contextvars into new threads so it might be a better idea to use contextvars instead of stack inspection.

Most of the examples included within trulens require additional packages not installed alongside trulens. You may be prompted to install them (with pip). The requirements file trulens/requirements.optional.txt contains the list of optional packages and their use if you'd like to install them all in one go.
To handle optional packages and provide clearer instructions to the user, we employ a context-manager-based scheme (see utils/imports.py) to import packages that may not be installed. The basic form of such imports can be seen in __init__.py:
with OptionalImports(messages=REQUIREMENT_LLAMA):\n from trulens.apps.llamaindex import TruLlama\n
This makes it so that TruLlama gets defined subsequently even if the import fails (because tru_llama imports llama_index which may not be installed). However, if the user imports TruLlama (via __init__.py) and tries to use it (call it, look up attribute, etc), the will be presented a message telling them that llama-index is optional and how to install it:
ModuleNotFoundError:\nllama-index package is required for instrumenting llama_index apps.\nYou should be able to install it with pip:\n\n pip install \"llama-index>=v0.9.14.post3\"\n
If a user imports directly from TruLlama (not by way of __init__.py), they will get that message immediately instead of upon use due to this line inside tru_llama.py:
This checks that the optional import system did not return a replacement for llama_index (under a context manager earlier in the file).
If used in conjunction, the optional imports context manager and assert_installed check can be simplified by storing a reference to to the OptionalImports instance which is returned by the context manager entrance:
with OptionalImports(messages=REQUIREMENT_LLAMA) as opt:\n import llama_index\n ...\n\nopt.assert_installed(llama_index)\n
assert_installed also returns the OptionalImports instance on success so assertions can be chained:

Releases are organized in <major>.<minor>.<patch> style. A release is made about every week around tuesday-thursday. Releases increment the minor version number. Occasionally bug-fix releases occur after a weekly release. Those increment only the patch number. No releases have yet made a major version increment. Those are expected to be major releases that introduce a large number of breaking changes.
Changes to the public API are governed by a deprecation process in three stages. In the warning period of no less than 6 weeks, the use of a deprecated package, module, or value will produce a warning but otherwise operate as expected. In the subsequent deprecated period of no less than 6 weeks, the use of that component will produce an error after the deprecation message. After these two periods, the deprecated capability will be completely removed.
Deprecation Process
0-6 weeks: Deprecation warning
6-12 weeks: Deprecation message and error
12+ weeks: Removal
Changes that result in non-backwards compatible functionality are also reflected in the version numbering. In such cases, the appropriate level version change will occur at the introduction of the warning period.
Starting 1.0, the trulens_eval package is being deprecated in favor of trulens and several associated required and optional packages. See trulens_eval migration for details.
Warning period: 2024-09-01 (trulens-eval==1.0.1) to 2024-10-14. Backwards compatibility during the warning period is provided by the new content of the trulens_eval package which provides aliases to the features in their new locations. See trulens_eval.
Deprecated period: 2024-10-14 to 2025-12-01. Usage of trulens_eval will produce errors indicating deprecation.
Removed expected 2024-12-01 Installation of the latest version of trulens_eval will be an error itself with a message that trulens_eval is no longer maintained.
Major new features are introduced to TruLens first in the form of experimental previews. Such features are indicated by the prefix experimental_. For example, the OTEL exporter for TruSession is specified with the experimental_otel_exporter parameter. Some features require additionally setting a flag before they are enabled. This is controlled by the TruSession.experimental_{enable,disable}_feature method:
from trulens.core.session import TruSession\nsession = TruSession()\nsession.experimental_enable_feature(\"otel_tracing\")\n\n# or\nfrom trulens.core.experimental import Feature\nsession.experimental_disable_feature(Feature.OTEL_TRACING)\n
If an experimental parameter like experimental_otel_exporter is used, some experimental flags may be set. For the OTEL exporter, the OTEL_EXPORTER flag is required and will be set.
Some features cannot be changed after some stages in the typical TruLens use-cases. OTEL tracing, for example, cannot be disabled once an app has been instrumented. An error will result in an attempt to change the feature after it has been \"locked\" by irreversible steps like instrumentation.
"},{"location":"trulens/contributing/policies/#experimental-features-pipeline","title":"Experimental Features Pipeline","text":"
While in development, the experimental features may change in significant ways. Eventually experimental features get adopted or removed.
For removal, experimental features do not have a deprecation period and will produce \"deprecated\" errors instead of warnings.
For adoption, the feature will be integrated somewhere in the API without the experimental_ prefix and use of that prefix/flag will instead raise an error indicating where in the stable API that feature relocated.

In this release, we re-aligned the groundedness feedback function with other LLM-based feedback functions. It's now faster and easier to define a groundedness feedback function, and can be done with a standard LLM provider rather than importing groundedness on its own. In addition, the custom groundedness aggregation required is now done by default.
Before:
from trulens_eval.feedback.provider.openai import OpenAI\nfrom trulens_eval.feedback import Groundedness\n\nprovider = OpenAI() # or any other LLM-based provider\ngrounded = Groundedness(groundedness_provider=provider)\nf_groundedness = (\n Feedback(grounded.groundedness_measure_with_cot_reasons, name = \"Groundedness\")\n .on(Select.RecordCalls.retrieve.rets.collect())\n .on_output()\n .aggregate(grounded.grounded_statements_aggregator)\n)\n
In natural language text, style/format proper names using italics if available. In Markdown, this can be done with a single underscore character on both sides of the term. In unstyled text, use the capitalization as below. This does not apply when referring to things like package names, classes, methods.
See pyproject.toml section [tool.ruff.lint.isort] on tooling to organize import statements.
Generally import modules only as per https://google.github.io/styleguide/pyguide.html#22-imports. That us:
from trulens.schema.record import Record # don't do this\nfrom trulens.schema import record as mod_record # do this instead\n
This prevents the record module from being loaded until something inside it is needed. If your uses of mod_record.Record are inside functions, this loading can be delayed as far as the execution of that function.
Import and rename modules:
from trulens.schema import record # don't do this\nfrom trulens.schema import record as record_schema # do this\n
This is especially important for module names which might cause name collisions with other things such as variables named record.
Keep module renames consistent:
from trulens.schema import X as X_schema\nfrom trulens.utils import X as X_utils\n\n# if X is inside some category of module Y:\nfrom trulens...Y import Y as X_Y\n# otherwise if X is not in some category of modules:\nfrom trulens... import X as mod_X\n
If an imported module is only used in type annotations, import it inside a TYPE_CHECKING block:
from typing import TYPE_CHECKING\n\nif TYPE_CHECKING:\n from trulens.schema import record as record_schema\n
Do not create exportable aliases (an alias that is listed in __all__ and refers to an element from some other module). Don't import aliases. Type aliases, even exportable ones are ok:
Circular imports may become an issue (error when executing your/trulens code, indicated by phrase \"likely due to circular imports\"). The Import guideline above may help alleviate the problem. A few more things can help:
Use annotations feature flag:
from __future__ import annotations\n
However, if your module contains pydantic models, you may need to run model_rebuild:
from __future__ import annotations\n\n...\n\nclass SomeModel(pydantic.BaseModel):\n\n some_attribute: some_module.SomeType\n\n...\n\nSomeModel.model_rebuild()\n
If you have multiple mutually referential models, you may need to rebuild only after all are defined.

Static tests run on multiple versions of python: 3.8, 3.9, 3.10, 3.11, and being a subset of unit tests, are also run on latest supported python, 3.12 . Some tests that require all optional packages to be installed run only on 3.11 as the latter python version does not support some of those optional packages.
This is a (likely incomplete) list of hacks present in the trulens library. They are likely a source of debugging problems so ideally they can be addressed/removed in time. This document is to serve as a warning in the meantime and a resource for hard-to-debug issues when they arise.
In notes below, \"HACK###\" can be used to find places in the code where the hack lives.
See instruments.py docstring for discussion why these are done.
Stack walking removed in favor of contextvars in 1.0.3. We inspect the call stack in process of tracking method invocation. It may be possible to replace this with contextvars.
\"HACK012\" -- In the optional imports scheme, we have to make sure that imports that happen from outside of trulens raise exceptions instead of producing dummies without raising exceptions.
See instruments.py docstring for discussion why these are done.
We override and wrap methods from other libraries to track their invocation or API use. Overriding for tracking invocation is done in the base instruments.py:Instrument class while for tracking costs are in the base Endpoint class.
\"HACK009\" -- Cannot reliably determine whether a function referred to by an object that implements __call__ has been instrumented. Hacks to avoid warnings about lack of instrumentation.
Fixed as of llama_index 0.9.26 or near there. \"HACK001\" -- trace_method decorator in llama_index does not preserve function signatures; we hack it so that it does.
\"HACK006\" -- endpoint needs to be added as a keyword arg with default value in some __init__ because pydantic overrides signature without default value otherwise.
\"HACK005\" -- model_validate inside WithClassInfo is implemented in decorated method because pydantic doesn't call it otherwise. It is uncertain whether this is a pydantic bug.
We dump attributes marked to be excluded by pydantic except our own classes. This is because some objects are of interest despite being marked to exclude. Example: RetrievalQA.retriever in langchain.
\"HACK004\" -- Outdated, need investigation whether it can be removed.
Partially fixed with asynchro module: async/sync code duplication -- Many of our methods are almost identical duplicates due to supporting both async and synced versions. Having trouble with a working approach to de-duplicated the identical code.
Fixed in endpoint code: \"HACK008\" -- async generator -- Some special handling is used for tracking costs when async generators are involved. See feedback/provider/endpoint/base.py.
\"HACK010\" -- cannot tell whether something is a coroutine and need additional checks in sync/desync.
\"HACK011\" -- older pythons don't allow use of Future as a type constructor in annotations. We define a dummy type Future in older versions of python to circumvent this but have to selectively import it to make sure type checking and mkdocs is done right.
\"HACK012\" -- same but with Queue.
Similarly, we define NoneType for older python versions.
\"HACK013\" -- when using from __future__ import annotations for more convenient type annotation specification, one may have to call pydantic's BaseModel.model_rebuild after all types references in annotations in that file have been defined for each model class that uses type annotations that reference types defined after its own definition (i.e. \"forward refs\").
\"HACK014\" -- cannot from trulens import schema in some places due to strange interaction with pydantic. Results in:
AttributeError: module 'pydantic' has no attribute 'v1'\n
It might be some interaction with from __future__ import annotations and/or OptionalImports.

For cases where argument specification names more than one value as an input, aggregation can be used.
Consider this feedback example:
# Context relevance between question and each context chunk.\nf_context_relevance = (\n Feedback(provider.context_relevance_with_cot_reasons, name = \"Context Relevance\")\n .on(Select.RecordCalls.retrieve.args.query)\n .on(Select.RecordCalls.retrieve.rets)\n .aggregate(np.mean)\n)\n
The last line aggregate(numpy.min) specifies how feedback outputs are to be aggregated. This only applies to cases where the argument specification names more than one value for an input. The second specification, for statement was of this type.
The input to aggregate must be a method which can be imported globally. This function is called on the float results of feedback function evaluations to produce a single float.
The default is numpy.mean.

Measuring the performance of LLM apps is a critical step in the path from development to production. You would not move a traditional ML system to production without first gaining confidence by measuring its accuracy on a representative test set.
However unlike in traditional machine learning, ground truth is sparse and often entirely unavailable.
Without ground truth on which to compute metrics on our LLM apps, feedback functions can be used to compute metrics for LLM applications.
"},{"location":"trulens/evaluation/feedback_functions/#what-is-a-feedback-function","title":"What is a feedback function?","text":"
Feedback functions, analogous to labeling functions, provide a programmatic method for generating evaluations on an application run. In our view, this method of evaluations is far more useful than general benchmarks because they measure the performance of your app, on your data, for your users.
Important Concept
TruLens constructs feedback functions by combining more general models, known as the feedback provider, and feedback implementation made up of carefully constructed prompts and custom logic tailored to perform a particular evaluation task.
This construction is composable and extensible.
Composable meaning that the user can choose to combine any feedback provider with any feedback implementation.
Extensible meaning that the user can extend a feedback provider with custom feedback implementations of the user's choosing.
Example
In a high stakes domain requiring evaluating long chunks of context, the user may choose to use a more expensive SOTA model.
In lower stakes, higher volume scenarios, the user may choose to use a smaller, cheaper model as the provider.
In either case, any feedback provider can be combined with a TruLens feedback implementation to ultimately compose the feedback function.
"},{"location":"trulens/evaluation/feedback_functions/anatomy/","title":"\ud83e\uddb4 Anatomy of Feedback Functions","text":"
The Feedback class contains the starting point for feedback function specification and evaluation. A typical use-case looks like this:
# Context relevance between question and each context chunk.\nf_context_relevance = (\n Feedback(\n provider.context_relevance_with_cot_reasons,\n name=\"Context Relevance\"\n )\n .on(Select.RecordCalls.retrieve.args.query)\n .on(Select.RecordCalls.retrieve.rets)\n .aggregate(numpy.mean)\n)\n
The provider is the back-end on which a given feedback function is run. Multiple underlying models are available througheach provider, such as GPT-4 or Llama-2. In many, but not all cases, the feedback implementation is shared cross providers (such as with LLM-based evaluations).
OpenAI.context_relevance is an example of a feedback function implementation.
Feedback implementations are simple callables that can be run on any arguments matching their signatures. In the example, the implementation has the following signature:
That is, context_relevance is a plain python method that accepts the prompt and context, both strings, and produces a float (assumed to be between 0.0 and 1.0).
The next line, on_input_output, specifies how the context_relevance arguments are to be determined from an app record or app definition. The general form of this specification is done using on but several shorthands are provided. For example, on_input_output states that the first two argument to context_relevance (prompt and context) are to be the main app input and the main output, respectively.
Read more about argument specification and selector shortcuts.
The last line aggregate(numpy.mean) specifies how feedback outputs are to be aggregated. This only applies to cases where the argument specification names more than one value for an input. The second specification, for statement was of this type. The input to aggregate must be a method which can be imported globally. This requirement is further elaborated in the next section. This function is called on the float results of feedback function evaluations to produce a single float. The default is numpy.mean.
TruLens constructs feedback functions by a feedback provider, and feedback implementation.
This page documents the feedback implementations available in TruLens.
Feedback functions are implemented in instances of the Provider class. They are made up of carefully constructed prompts and custom logic tailored to perform a particular evaluation task.
The implementation of generation-based feedback functions can consist of:
Instructions to a generative model (LLM) on how to perform a particular evaluation task. These instructions are sent to the LLM as a system message, and often consist of a rubric.
A template that passes the arguments of the feedback function to the LLM. This template containing the arguments of the feedback function is sent to the LLM as a user message.
A method for parsing, validating, and normalizing the output of the LLM, accomplished by generate_score.
Custom Logic to perform data preprocessing tasks before the LLM is called for evaluation.
Additional logic to perform postprocessing tasks using the LLM output.
TruLens can also provide reasons using chain-of-thought methodology. Such implementations are denoted by method names ending in _with_cot_reasons. These implementations illicit the LLM to provide reasons for its score, accomplished by generate_score_and_reasons.

Running \"chain of thought evaluations\" is another use case for extending providers. Doing so follows a similar process as above, where the base provider (such as AzureOpenAI) is subclassed.
For this case, the method generate_score_and_reasons can be used to extract both the score and chain of thought reasons from the LLM response.
To use this method, the prompt used should include the COT_REASONS_TEMPLATE available from the TruLens prompts library (trulens.feedback.prompts).

Feedback functions are an extensible framework for evaluating LLMs. You can add your own feedback functions to evaluate the qualities required by your application by simply creating a new provider class and feedback function in your notebook. If your contributions would be useful for others, we encourage you to contribute to TruLens!
Feedback functions are organized by model provider into Provider classes.
The process for adding new feedback functions is:
Create a new Provider class or locate an existing one that applies to your feedback function. If your feedback function does not rely on a model provider, you can create a standalone class. Add the new feedback function method to your selected class. Your new method can either take a single text (str) as a parameter or both prompt (str) and response (str). It should return a float between 0 (worst) and 1 (best).
In addition to calling your own methods, you can also extend stock feedback providers (such as OpenAI, AzureOpenAI, Bedrock) to custom feedback implementations. This can be especially useful for tweaking stock feedback functions, or running custom feedback function prompts while letting TruLens handle the backend LLM provider.
This is done by subclassing the provider you wish to extend, and using the generate_score method that runs the provided prompt with your specified provider, and extracts a float score from 0-1. Your prompt should request the LLM respond on the scale from 0 to 10, then the generate_score method will normalize to 0-1.
Trulens also supports multi-output feedback functions. As a typical feedback function will output a float between 0 and 1, multi-output should output a dictionary of output_key to a float between 0 and 1. The feedbacks table will display the feedback with column feedback_name:::outputkey
Uses Huggingface's truera/context_relevance model, a model that uses computes the relevance of a given context to the prompt. The model can be found at https://huggingface.co/truera/context_relevance.
A measure to track if the source material supports each sentence in the statement using an NLI model.
First the response will be split into statements using a sentence tokenizer.The NLI model will process each statement using a natural language inference model, and will use the entire source.
Evaluates the hallucination score for a combined input of two statements as a float 0<x<1 representing a true/false boolean. if the return is greater than 0.5 the statement is evaluated as true. if the return is less than 0.5 the statement is evaluated as a hallucination.
Example
from trulens.providers.huggingface import Huggingface\nhuggingface_provider = Huggingface()\n\nscore = huggingface_provider.hallucination_evaluator(\"The sky is blue. [SEP] Apples are red , the grass is green.\")\n

To further explain how the function works under the hood, consider the statement:
\"Hi. I'm here to help. The university of Washington is a public research university. UW's connections to major corporations in Seattle contribute to its reputation as a hub for innovation and technology\"
The function will split the statement into its component sentences:
\"Hi.\"
\"I'm here to help.\"
\"The university of Washington is a public research university.\"
\"UW's connections to major corporations in Seattle contribute to its reputation as a hub for innovation and technology\"
Next, trivial statements are removed, leaving only:
\"The university of Washington is a public research university.\"
\"UW's connections to major corporations in Seattle contribute to its reputation as a hub for innovation and technology\"
The LLM will then process the statement, to assess the groundedness of the statement.
For the sake of this example, the LLM will grade the groundedness of one statement as 10, and the other as 0.
Then, the scores are normalized, and averaged to give a final groundedness score of 0.5.
A measure to track if the source material supports each sentence in the statement using an LLM provider.
The statement will first be split by a tokenizer into its component sentences.
Then, trivial statements are eliminated so as to not delete the evaluation.
The LLM will process each statement, using chain of thought methodology to emit the reasons.
In the case of abstentions, such as 'I do not know', the LLM will be asked to consider the answerability of the question given the source material.
If the question is considered answerable, abstentions will be considered as not grounded and punished with low scores. Otherwise, unanswerable abstentions will be considered grounded.

TruLens constructs feedback functions by combining more general models, known as the feedback provider, and feedback implementation made up of carefully constructed prompts and custom logic tailored to perform a particular evaluation task.
This page documents the feedback providers available in TruLens.
There are three categories of such providers as well as combination providers that make use of one or more of these providers to offer additional feedback functions based capabilities of the constituent providers.
Feedback selection is the process of determining which components of your application to evaluate.
This is useful because today's LLM applications are increasingly complex. Chaining together components such as planning, retrievel, tool selection, synthesis, and more; each component can be a source of error.
This also makes the instrumentation and evaluation of LLM applications inseparable. To evaluate the inner components of an application, we first need access to them.
As a reminder, a typical feedback definition looks like this:
on_input_output is one of many available shortcuts to simplify the selection of components for evaluation. We'll cover that in a later section.
The selector, on_input_output, specifies how the language_match arguments are to be determined from an app record or app definition. The general form of this specification is done using on but several shorthands are provided. on_input_output states that the first two argument to language_match (text1 and text2) are to be the main app input and the main output, respectively.
This flexibility to select and evaluate any component of your application allows the developer to be unconstrained in their creativity. The evaluation framework should not designate how you can build your app.
LLM applications come in all shapes and sizes and with a variety of different control flows. As a result it\u2019s a challenge to consistently evaluate parts of an LLM application trace.
Therefore, we\u2019ve adapted the use of lenses to refer to parts of an LLM stack trace and use those when defining evaluations. For example, the following lens refers to the input to the retrieve step of the app called query.
Example
Select.RecordCalls.retrieve.args.query\n
Such lenses can then be used to define evaluations as so:
Example
# Context relevance between question and each context chunk.\nf_context_relevance = (\n Feedback(provider.context_relevance_with_cot_reasons, name = \"Context Relevance\")\n .on(Select.RecordCalls.retrieve.args.query)\n .on(Select.RecordCalls.retrieve.rets)\n .aggregate(np.mean)\n)\n
In most cases, the Select object produces only a single item but can also address multiple items.
For example: Select.RecordCalls.retrieve.args.query refers to only one item.
However, Select.RecordCalls.retrieve.rets refers to multiple items. In this case, the documents returned by the retrieve method. These items can be evaluated separately, as shown above, or can be collected into an array for evaluation with .collect(). This is most commonly used for groundedness evaluations.
Example
f_groundedness = (\n Feedback(provider.groundedness_measure_with_cot_reasons, name = \"Groundedness\")\n .on(Select.RecordCalls.retrieve.rets.collect())\n .on_output()\n)\n
Selectors can also access multiple calls to the same component. In agentic applications, this is an increasingly common practice. For example, an agent could complete multiple calls to a retrieve method to complete the task required.
For example, the following method returns only the returned context documents from the first invocation of retrieve.
context = Select.RecordCalls.retrieve.rets.rets[:]\n# Same as context = context_method[0].rets[:]\n
Alternatively, adding [:] after the method name retrieve returns context documents from all invocations of retrieve.
"},{"location":"trulens/evaluation/feedback_selectors/selecting_components/#understanding-the-structure-of-your-app","title":"Understanding the structure of your app","text":"
Because LLM apps have a wide variation in their structure, the feedback selector construction can also vary widely. To construct the feedback selector, you must first understand the structure of your application.
In python, you can access the JSON structure with with_record methods and then calling layout_calls_as_app.
The application structure can also be viewed in the TruLens user interface. You can view this structure on the Evaluations page by scrolling down to the Timeline.
The top level record also contains these helper accessors
RecordInput = Record.main_input -- points to the main input part of a Record. This is the first argument to the root method of an app (for LangChain Chains this is the __call__ method).
RecordOutput = Record.main_output -- points to the main output part of a Record. This is the output of the root method of an app (i.e. __call__ for LangChain Chains).
RecordCalls = Record.app -- points to the root of the app-structured mirror of calls in a record. See App-organized Calls Section above.
"},{"location":"trulens/evaluation/feedback_selectors/selecting_components/#multiple-inputs-per-argument","title":"Multiple Inputs Per Argument","text":"
As in the f_context_relevance example, a selector for a single argument may point to more than one aspect of a record/app. These are specified using the slice or lists in key/index positions. In that case, the feedback function is evaluated multiple times, its outputs collected, and finally aggregated into a main feedback result.
The collection of values for each argument of feedback implementation is collected and every combination of argument-to-value mapping is evaluated with a feedback definition. This may produce a large number of evaluations if more than one argument names multiple values. In the dashboard, all individual invocations of a feedback implementation are shown alongside the final aggregate result.

Create a copy of the json serialized app with the enclosed app being initialized to its initial state before any records are produced (i.e. blank memory).
"},{"location":"trulens/evaluation/feedback_selectors/selecting_components/#calls-made-by-app-components","title":"Calls made by App Components","text":"
When evaluating a feedback function, Records are augmented with app/component calls. For example, if the instrumented app contains a component combine_docs_chain then app.combine_docs_chain will contain calls to methods of this component. app.combine_docs_chain._call will contain a RecordAppCall (see schema.py) with information about the inputs/outputs/metadata regarding the _call call to that component. Selecting this information is the reason behind the Select.RecordCalls alias.
You can inspect the components making up your app via the App method print_instrumented.
on_input_output is one of many available shortcuts to simplify the selection of components for evaluation.
The selector, on_input_output, specifies how the language_match arguments are to be determined from an app record or app definition. The general form of this specification is done using on but several shorthands are provided. on_input_output states that the first two argument to language_match (text1 and text2) are to be the main app input and the main output, respectively.
Several utility methods starting with .on provide shorthands:
on_input(arg) == on_prompt(arg: Optional[str]) -- both specify that the next unspecified argument or arg should be the main app input.
on_output(arg) == on_response(arg: Optional[str]) -- specify that the next argument or arg should be the main app output.
on_input_output() == on_input().on_output() -- specifies that the first two arguments of implementation should be the main app input and main app output, respectively.
on_default() -- depending on signature of implementation uses either on_output() if it has a single argument, or on_input_output if it has two arguments.
Some wrappers include additional shorthands:

{'Code implementation': [\n 'What are the steps to follow when implementing code based on the provided instructions?',\n 'What is the required format for each file when outputting the content, including all code?'\n ],\n 'Short term memory limitations': [\n 'What is the capacity of short-term memory and how long does it last?',\n 'What are the two subtypes of long-term memory and what types of information do they store?'\n ],\n 'Planning and task decomposition challenges': [\n 'What are the challenges faced by LLMs in adjusting plans when encountering unexpected errors during long-term planning?',\n 'How does Tree of Thoughts extend the Chain of Thought technique for task decomposition and what search processes can be used in this approach?'\n ]\n}\n
Optionally, you can also provide a list of examples (few-shot) to guide the LLM app to a particular type of question.
Example:
examples = [\n \"What is sensory memory?\",\n \"How much information can be stored in short term memory?\"\n]\n\nfewshot_test_set = test.generate_test_set(\n test_breadth = 3,\n test_depth = 2,\n examples = examples\n)\nfewshot_test_set\n
Returns:
{'Code implementation': [\n 'What are the subcategories of sensory memory?',\n 'What is the capacity of short-term memory according to Miller (1956)?'\n ],\n 'Short term memory limitations': [\n 'What is the duration of sensory memory?',\n 'What are the limitations of short-term memory in terms of context capacity?'\n ],\n 'Planning and task decomposition challenges': [\n 'How long does sensory memory typically last?',\n 'What are the challenges in long-term planning and task decomposition?'\n ]\n}\n
In combination with record metadata logging, this gives you the ability to understand the performance of your application across different prompt categories.

In many cases, developers have already logged runs of an LLM app they wish to evaluate or wish to log their app using another system. Feedback functions can also be run on existing data, independent of the recorder.
At the most basic level, feedback implementations are simple callables that can be run on any arguments matching their signatures like so:
Running the feedback implementation in isolation will not log the evaluation results in TruLens.
In the case that you have already logged a run of your application with TruLens and have the record available, the process for running an (additional) evaluation on that record is by using tru.run_feedback_functions:
tru_rag = TruCustomApp(rag, app_name=\"RAG\", app_version=\"v1\")\n\nresult, record = tru_rag.with_record(rag.query, \"How many professors are at UW in Seattle?\")\nfeedback_results = tru.run_feedback_functions(record, feedbacks=[f_lang_match, f_qa_relevance, f_context_relevance])\ntru.add_feedbacks(feedback_results)\n
If your application was run (and logged) outside of TruLens, TruVirtual can be used to ingest and evaluate the logs.
The first step to loading your app logs into TruLens is creating a virtual app. This virtual app can be a plain dictionary or use our VirtualApp class to store any information you would like. You can refer to these values for evaluating feedback.
virtual_app = dict(\n llm=dict(\n modelname=\"some llm component model name\"\n ),\n template=\"information about the template I used in my app\",\n debug=\"all of these fields are completely optional\"\n)\nfrom trulens.core import Select, VirtualApp\n\nvirtual_app = VirtualApp(virtual_app) # can start with the prior dictionary\nvirtual_app[Select.RecordCalls.llm.maxtokens] = 1024\n
When setting up the virtual app, you should also include any components that you would like to evaluate in the virtual app. This can be done using the Select class. Using selectors here lets use reuse the setup you use to define feedback functions. Below you can see how to set up a virtual app with a retriever component, which will be used later in the example for feedback evaluation.
from trulens.core import Select\nretriever_component = Select.RecordCalls.retriever\nvirtual_app[retriever_component] = \"this is the retriever component\"\n
Now that you've set up your virtual app, you can use it to store your logged data.
To incorporate your data into TruLens, you have two options. You can either create a Record directly, or you can use the VirtualRecord class, which is designed to help you build records so they can be ingested to TruLens.
The parameters you'll use with VirtualRecord are the same as those for Record, with one key difference: calls are specified using selectors.
In the example below, we add two records. Each record includes the inputs and outputs for a context retrieval component. Remember, you only need to provide the information that you want to track or evaluate. The selectors are references to methods that can be selected for feedback, as we'll demonstrate below.
from trulens.apps.virtual import VirtualRecord\n\n# The selector for a presumed context retrieval component's call to\n# `get_context`. The names are arbitrary but may be useful for readability on\n# your end.\ncontext_call = retriever_component.get_context\n\nrec1 = VirtualRecord(\n main_input=\"Where is Germany?\",\n main_output=\"Germany is in Europe\",\n calls=\n {\n context_call: dict(\n args=[\"Where is Germany?\"],\n rets=[\"Germany is a country located in Europe.\"]\n )\n }\n )\nrec2 = VirtualRecord(\n main_input=\"Where is Germany?\",\n main_output=\"Poland is in Europe\",\n calls=\n {\n context_call: dict(\n args=[\"Where is Germany?\"],\n rets=[\"Poland is a country located in Europe.\"]\n )\n }\n )\n\ndata = [rec1, rec2]\n
Alternatively, suppose we have an existing dataframe of prompts, contexts and responses we wish to ingest.
import pandas as pd\n\ndata = {\n 'prompt': ['Where is Germany?', 'What is the capital of France?'],\n 'response': ['Germany is in Europe', 'The capital of France is Paris'],\n 'context': ['Germany is a country located in Europe.', 'France is a country in Europe and its capital is Paris.']\n}\ndf = pd.DataFrame(data)\ndf.head()\n
To ingest the data in this form, we can iterate through the dataframe to ingest each prompt, context and response into virtual records.
Now that we've ingested constructed the virtual records, we can build our feedback functions. This is done just the same as normal, except the context selector will instead refer to the new context_call we added to the virtual record.
from trulens.providers.openai import OpenAI\nfrom trulens.core import Feedback\n\n# Initialize provider class\nopenai = OpenAI()\n\n# Select context to be used in feedback. We select the return values of the\n# virtual `get_context` call in the virtual `retriever` component. Names are\n# arbitrary except for `rets`.\ncontext = context_call.rets[:]\n\n# Question/statement relevance between question and each context chunk.\nf_context_relevance = (\n Feedback(openai.context_relevance)\n .on_input()\n .on(context)\n)\n
Then, the feedback functions can be passed to TruVirtual to construct the recorder. Most of the fields that other non-virtual apps take can also be specified here.
To finally ingest the record and run feedbacks, we can use add_record.
for record in data:\n virtual_recorder.add_record(rec)\n
To optionally store metadata about your application, you can also pass an arbitrary dict to VirtualApp. This information can also be used in evaluation.
virtual_app = dict(\n llm=dict(\n modelname=\"some llm component model name\"\n ),\n template=\"information about the template I used in my app\",\n debug=\"all of these fields are completely optional\"\n)\n\nfrom trulens.core.schema import Select\nfrom trulens.apps.virtual import VirtualApp\n\nvirtual_app = VirtualApp(virtual_app)\n
This can be particularly useful for storing the components of an LLM app to be later used for evaluation.
retriever_component = Select.RecordCalls.retriever\nvirtual_app[retriever_component] = \"this is the retriever component\"\n
"},{"location":"trulens/evaluation/running_feedback_functions/with_app/","title":"Running with your app","text":"
The primary method for evaluating LLM apps is by running feedback functions with your app.
To do so, you first need to define the wrap the specified feedback implementation with Feedback and select what components of your app to evaluate. Optionally, you can also select an aggregation method.
Once you've defined the feedback functions to run with your application, you can then pass them as a list to the instrumentation class of your choice, along with the app itself. These make up the recorder.
from trulens.apps.langchain import TruChain\n# f_lang_match, f_qa_relevance, f_context_relevance are feedback functions\ntru_recorder = TruChain(\n chain,\n app_name='ChatApplication',\n app_version=\"Chain1\",\n feedbacks=[f_lang_match, f_qa_relevance, f_context_relevance])\n
Now that you've included the evaluations as a component of your recorder, they are able to be run with your application. By default, feedback functions will be run in the same process as the app. This is known as the feedback mode: with_app_thread.
with tru_recorder as recording:\n chain(\"\"What is langchain?\")\n
In addition to with_app_thread, there are a number of other manners of running feedback functions. These are accessed by the feedback mode and included when you construct the recorder, like so:
TruLens relies on feedback functions to score the performance of LLM apps, which are implemented across a variety of LLMs and smaller models. The numerical scoring scheme adopted by TruLens' feedback functions is intuitive for generating aggregated results from eval runs that are easy to interpret and visualize across different applications of interest. However, it begs the question how trustworthy these scores actually are, given they are at their core next-token-prediction-style generation from meticulously designed prompts.
Consequently, these feedback functions face typical large language model (LLM) challenges in rigorous production environments, including prompt sensitivity and non-determinism, especially when incorporating Mixture-of-Experts and model-as-a-service solutions like those from OpenAI, Mistral, and others. Drawing inspiration from works on Judging LLM-as-a-Judge, we outline findings from our analysis of feedback function performance against task-aligned benchmark data. To accomplish this, we first need to align feedback function tasks to relevant benchmarks in order to gain access to large scale ground truth data for the feedback functions. We then are able to easily compute metrics across a variety of implementations and models.
Observing that many summarization benchmarks, such as those found at SummEval, use human annotation of numerical scores, we propose to frame the problem of evaluating groundedness tasks as evaluating a summarization system. In particular, we generate test cases from SummEval.
SummEval is one of the datasets dedicated to automated evaluations on summarization tasks, which are closely related to the groundedness evaluation in RAG with the retrieved context (i.e. the source) and response (i.e. the summary). It contains human annotation of numerical score (1 to 5) comprised of scoring from 3 human expert annotators and 5 crowd-sourced annotators. There are 16 models being used for generation in total for 100 paragraphs in the test set, so there are a total of 16,000 machine-generated summaries. Each paragraph also has several human-written summaries for comparative analysis.
For evaluating groundedness feedback functions, we compute the annotated \"consistency\" scores, a measure of whether the summarized response is factually consistent with the source texts and hence can be used as a proxy to evaluate groundedness in our RAG triad, and normalized to 0 to 1 score as our expected_score and to match the output of feedback functions.
See the code.

In many ways, feedbacks can be thought of as LLM apps themselves. Given text, they return some result. Thinking in this way, we can use TruLens to evaluate and track our feedback quality. We can even do this for different models (e.g. gpt-3.5 and gpt-4) or prompting schemes (such as chain-of-thought reasoning).

The numerical scoring scheme adopted by TruLens feedback functions is intuitive for generating aggregated results from eval runs that are easy to interpret and visualize across different applications of interest. However, it begs the question how trustworthy these scores actually are, given they are at their core next-token-prediction-style generation from meticulously designed prompts. Consequently, these feedback functions face typical large language model (LLM) challenges in rigorous production environments, including prompt sensitivity and non-determinism, especially when incorporating Mixture-of-Experts and model-as-a-service solutions like those from OpenAI.
Another frequent inquiry from the community concerns the intrinsic semantic significance, or lack thereof, of feedback scores\u2014for example, how one would interpret and instrument with a score of 0.9 when assessing context relevance in a RAG application or whether a harmfulness score of 0.7 from GPT-3.5 equates to the same from Llama-2-7b.
For simpler meta-evaluation tasks, when human numerical scores are available in the benchmark datasets, such as SummEval, it's a lot more straightforward to evaluate feedback functions as long as we can define reasonable correlation between the task of the feedback function and the ones available in the benchmarks. Check out our preliminary work on evaluating our own groundedness feedback functions: https://www.trulens.org/trulens/groundedness_smoke_tests/#groundedness-evaluations and our previous blog, where the groundedness metric in the context of RAG can be viewed as equivalent to the consistency metric defined in the SummEval benchmark. In those cases, calculating MAE between our feedback scores and the golden set's human scores can readily provide insights on how well the groundedness LLM-based feedback functions are aligned with human preferences.
Yet, acquiring high-quality, numerically scored datasets is challenging and costly, a sentiment echoed across institutions and companies working on RLFH dataset annotation.
Observing that many information retrieval (IR) benchmarks use binary labels, we propose to frame the problem of evaluating LLM-based feedback functions (meta-evaluation) as evaluating a recommender system. In essence, we argue the relative importance or ranking based on the score assignments is all you need to achieve meta-evaluation against human golden sets. The intuition is that it is a sufficient proxy to trustworthiness if feedback functions demonstrate discriminative capabilities that reliably and consistently assign items, be it context chunks or generated responses, with weights and ordering closely mirroring human preferences.
In this following section, we illustrate how we conduct meta-evaluation experiments on one of Trulens most widely used feedback functions: context relevance and share how well they are aligned with human preferences in practice.

We can even do this for different models (e.g. gpt-3.5 and gpt-4) or prompting schemes (such as chain-of-thought reasoning).
This notebook follows an evaluation of a set of test cases generated from human annotated datasets. In particular, we generate test cases from SummEval.
SummEval is one of the datasets dedicated to automated evaluations on summarization tasks, which are closely related to the groundedness evaluation in RAG with the retrieved context (i.e. the source) and response (i.e. the summary). It contains human annotation of numerical score (1 to 5) comprised of scoring from 3 human expert annotators and 5 crowd-sourced annotators. There are 16 models being used for generation in total for 100 paragraphs in the test set, so there are a total of 16,000 machine-generated summaries. Each paragraph also has several human-written summaries for comparative analysis.
For evaluating groundedness feedback functions, we compute the annotated \"consistency\" scores, a measure of whether the summarized response is factually consistent with the source texts and hence can be used as a proxy to evaluate groundedness in our RAG triad, and normalized to 0 to 1 score as our expected_score and to match the output of feedback functions.

Info
TruLens 1.0 is now available. Read more and check out the migration guide
General and \ud83e\udd91TruLens-specific concepts.
Agent. A Component of an Application or the entirety of an application that providers a natural language interface to some set of capabilities typically incorporating Tools to invoke or query local or remote services, while maintaining its state via Memory. The user of an agent may be a human, a tool, or another agent. See also Multi Agent System.
Application or App. An \"application\" that is tracked by \ud83e\udd91TruLens. Abstract definition of this tracking corresponds to App. We offer special support for LangChain via TruChain, LlamaIndex via TruLlama, and NeMo Guardrails via TruRails Applications as well as custom apps via TruBasicApp or TruCustomApp, and apps that already come with Traces via TruVirtual.
Chain. A LangChain App.
Chain of Thought. The use of an Agent to deconstruct its tasks and to structure, analyze, and refine its Completions.
Completion, Generation. The process or result of LLM responding to some Prompt.
Component. Part of an Application giving it some capability. Common components include:
Retriever
Memory
Tool
Agent
Prompt Template
LLM
Embedding. A real vector representation of some piece of text. Can be used to find related pieces of text in a Retrieval.
Eval, Evals, Evaluation. Process or result of method that scores the outputs or aspects of a Trace. In \ud83e\udd91TruLens, our scores are real numbers between 0 and 1.
Feedback. See Evaluation.
Feedback Function. A method that implements an Evaluation. This corresponds to Feedback.
Fine-tuning. The process of training an already pre-trained model on additional data. While the initial training of a Large Language Model is resource intensive (read \"large\"), the subsequent fine-tuning may not be and can improve the performance of the LLM on data that sufficiently deviates or specializes its original training data. Fine-tuning aims to preserve the generality of the original and transfer of its capabilities to specialized tasks. Examples include fining-tuning on:
financial articles
medical notes
synthetic languages (programming or otherwise)
While fine-tuning generally requires access to the original model parameters, some model providers give users the ability to fine-tune through their remote APIs.
Generation. See Completion.
Human Feedback. A feedback that is provided by a human, e.g. a thumbs up/down in response to a Completion.
In-Context Learning. The use of examples in an Instruction Prompt to help an LLM generate intended Completions. See also Shot.
Instruction Prompt, System Prompt. A part of a Prompt given to an LLM to complete that contains instructions describing the task that the Completion should solve. Sometimes such prompts include examples of correct or intended completions (see Shots). A prompt that does not include examples is said to be Zero Shot.
Language Model. A model whose tasks is to model text distributions typically in the form of predicting token distributions for text that follows the given prefix. Propriety models usually do not give users access to token distributions and instead Complete a piece of input text via multiple token predictions and methods such as beam search.
LLM, Large Language Model (see Language Model). The Component of an Application that performs Completion. LLM's are usually trained on a large amount of text across multiple natural and synthetic languages. They are also trained to follow instructions provided in their Instruction Prompt. This makes them general in that they can be applied to many structured or unstructured tasks and even tasks which they have not seen in their training data (See Instruction Prompt, In-Context Learning). LLMs can be further improved to rare/specialized settings using Fine-Tuning.
Memory. The state maintained by an Application or an Agent indicating anything relevant to continuing, refining, or guiding it towards its goals. Memory is provided as Context in Prompts and is updated when new relevant context is processed, be it a user prompt or the results of the invocation of some Tool. As Memory is included in Prompts, it can be a natural language description of the state of the app/agent. To limit to size if memory, Summarization is often used.
Multi-Agent System. The use of multiple Agents incentivized to interact with each other to implement some capability. While the term predates LLMs, the convenience of the common natural language interface makes the approach much easier to implement.
Prompt. The text that an LLM completes during Completion. In chat applications. See also Instruction Prompt, Prompt Template.
Prompt Template. A piece of text with placeholders to be filled in in order to build a Prompt for a given task. A Prompt Template will typically include the Instruction Prompt with placeholders for things like Context, Memory, or Application configuration parameters.
Provider. A system that provides the ability to execute models, either LLMs or classification models. In \ud83e\udd91TruLens, Feedback Functions make use of Providers to invoke models for Evaluation.
RAG, Retrieval Augmented Generation. A common organization of Applications that combine a Retrieval with an LLM to produce Completions that incorporate information that an LLM alone may not be aware of.
RAG Triad (\ud83e\udd91TruLens-specific concept). A combination of three Feedback Functions meant to EvaluateRetrieval steps in Applications.
Record. A \"record\" of the execution of a single execution of an app. Single execution means invocation of some top-level app method. Corresponds to Record
Note
This will be renamed to Trace in the future.
Retrieval, Retriever. The process or result (or the Component that performs this) of looking up pieces of text relevant to a Prompt to provide as Context to an LLM. Typically this is done using an Embedding representations.
Selector (\ud83e\udd91TruLens-specific concept). A specification of the source of data from a Trace to use as inputs to a Feedback Function. This corresponds to Lens and utilities Select.
Shot, Zero Shot, Few Shot, <Quantity>-Shot. Zero Shot describes prompts that do not have any examples and only offer a natural language description of the task to be solved, while <Quantity>-Shot indicate some <Quantity> of examples are provided. The \"shot\" terminology predates instruction-based LLM's where techniques then used other information to handle unseed classes such as label descriptions in the seen/trained data. In-context Learning is the recent term that describes the use of examples in Instruction Prompts.
Span. Some unit of work logged as part of a record. Corresponds to current \ud83e\udd91RecordAppCallMethod.
Summarization. The task of condensing some natural language text into a smaller bit of natural language text that preserves the most important parts of the text. This can be targeted towards humans or otherwise. It can also be used to maintain consize Memory in an LLMApplication or Agent. Summarization can be performed by an LLM using a specific Instruction Prompt.
Tool. A piece of functionality that can be invoked by an Application or Agent. This commonly includes interfaces to services such as search (generic search via google or more specific like IMDB for movies). Tools may also perform actions such as submitting comments to github issues. A Tool may also encapsulate an interface to an Agent for use as a component in a larger Application.
Trace. See Record.

Feedback functions, analogous to labeling functions, provide a programmatic method for generating evaluations on an application run. The TruLens implementation of feedback functions wrap a supported provider\u2019s model, such as a relevance model or a sentiment classifier, that is repurposed to provide evaluations. Often, for the most flexibility, this model can be another LLM.
It can be useful to think of the range of evaluations on two axis: Scalable and Meaningful.
In early development stages, we recommend starting with domain expert evaluations. These evaluations are often completed by the developers themselves and represent the core use cases your app is expected to complete. This allows you to deeply understand the performance of your app, but lacks scale.
See this example notebook to learn how to run ground truth evaluations with TruLens.
After you have completed early evaluations and have gained more confidence in your app, it is often useful to gather human feedback. This can often be in the form of binary (up/down) feedback provided by your users. This is more slightly scalable than ground truth evals, but struggles with variance and can still be expensive to collect.
See this example notebook to learn how to log human feedback with TruLens.
Next, it is a common practice to try traditional NLP metrics for evaluations such as BLEU and ROUGE. While these evals are extremely scalable, they are often too syntactic and lack the ability to provide meaningful information on the performance of your app.
"},{"location":"trulens/getting_started/core_concepts/feedback_functions/#medium-language-model-evaluations","title":"Medium Language Model Evaluations","text":"
Medium Language Models (like BERT) can be a sweet spot for LLM app evaluations at scale. This size of model is relatively cheap to run (scalable) and can also provide nuanced, meaningful feedback on your app. In some cases, these models need to be fine-tuned to provide the right feedback for your domain.
TruLens provides a number of feedback functions out of the box that rely on this style of model such as groundedness NLI, sentiment, language match, moderation and more.
"},{"location":"trulens/getting_started/core_concepts/feedback_functions/#large-language-model-evaluations","title":"Large Language Model Evaluations","text":"
Large Language Models can also provide meaningful and flexible feedback on LLM app performance. Often through simple prompting, LLM-based evaluations can provide meaningful evaluations that agree with humans at a very high rate. Additionally, they can be easily augmented with LLM-provided reasoning to justify high or low evaluation scores that are useful for debugging.
Depending on the size and nature of the LLM, these evaluations can be quite expensive at scale.
See this example notebook to learn how to run LLM-based evaluations with TruLens.

TruLens adapts \u2018honest, harmless, helpful\u2019 as desirable criteria for LLM apps from Anthropic. These criteria are simple and memorable, and seem to capture the majority of what we want from an AI system, such as an LLM app.
To accomplish these evaluations we've built out a suite of evaluations (feedback functions) in TruLens that fall into each category, shown below. These feedback functions provide a starting point for ensuring your LLM app is performant and aligned.
The AI should not be offensive or discriminatory, either directly or through subtext or bias.
When asked to aid in a dangerous act (e.g. building a bomb), the AI should politely refuse. Ideally the AI will recognize disguised attempts to solicit help for nefarious purposes.
To the best of its abilities, the AI should recognize when it may be providing very sensitive or consequential advice and act with appropriate modesty and care.
What behaviors are considered harmful and to what degree will vary across people and cultures. It will also be context-dependent, i.e. it will depend on the nature of the use.
The AI should make a clear attempt to perform the task or answer the question posed (as long as this isn\u2019t harmful). It should do this as concisely and efficiently as possible.
Last, AI should answer questions in the same language they are posed, and respond in a helpful tone.
RAGs have become the standard architecture for providing LLMs with context in order to avoid hallucinations. However even RAGs can suffer from hallucination, as is often the case when the retrieval fails to retrieve sufficient context or even retrieves irrelevant context that is then weaved into the LLM\u2019s response.
TruEra has innovated the RAG triad to evaluate for hallucinations along each edge of the RAG architecture, shown below:
The RAG triad is made up of 3 evaluations: context relevance, groundedness and answer relevance. Satisfactory evaluations on each provides us confidence that our LLM app is free from hallucination.
The first step of any RAG application is retrieval; to verify the quality of our retrieval, we want to make sure that each chunk of context is relevant to the input query. This is critical because this context will be used by the LLM to form an answer, so any irrelevant information in the context could be weaved into a hallucination. TruLens enables you to evaluate context relevance by using the structure of the serialized record.
After the context is retrieved, it is then formed into an answer by an LLM. LLMs are often prone to stray from the facts provided, exaggerating or expanding to a correct-sounding answer. To verify the groundedness of our application, we can separate the response into individual claims and independently search for evidence that supports each within the retrieved context.
Last, our response still needs to helpfully answer the original question. We can verify this by evaluating the relevance of the final response to the user input.
"},{"location":"trulens/getting_started/core_concepts/rag_triad/#putting-it-together","title":"Putting it together","text":"
By reaching satisfactory evaluations for this triad, we can make a nuanced statement about our application\u2019s correctness; our application is verified to be hallucination free up to the limit of its knowledge base. In other words, if the vector database contains only accurate information, then the answers provided by the RAG are also accurate.
To see the RAG triad in action, check out the TruLens Quickstart
TruLens provides a broad set of capabilities for evaluating and tracking applications. In addition, TruLens ships with native tools for examining traces and evaluations in the form of a complete dashboard, and components that can be added to streamlit apps.
To view and examine application logs and feedback results, TruLens provides a built-in Streamlit dashboard. That app has two pages, the Leaderboard which displays aggregate feedback results and metadata for each application version, and the Evaluations page where you can more closely examine individual traces and feedback results. This dashboard is launched by run_dashboard, and will run from a database url you specify with TruSession().
Launch the TruLens dashboard
from trulens.dashboard import run_dashboard\nsession = TruSession(database_url = ...) # or default.sqlite by default\nrun_dashboard(session)\n
By default, the dashboard will find and run on an unused port number. You can also specify a port number for the dashboard to run on. The function will output a link where the dashboard is running.
Specify a port
from trulens.dashboard import run_dashboard\nrun_dashboard(port=8502)\n
Note
If you are running in Google Colab, run_dashboard() will output a tunnel website and IP address that can be entered into the tunnel website.
In addition to the complete dashboard, several of the dashboard components can be used on their own and added to existing Streamlit dashboards.
Streamlit is an easy way to create python scripts into shareable web applications, and has become a popular way to interact with generative AI technology. Several TruLens UI components are now accessible for adding to Streamlit dashboards using the TruLens Streamlit module.
Consider the below app.py which consists of a simple RAG application that is already logged and evaluated with TruLens. Notice in particular, that we are getting both the application's response and record.
Simple Streamlit app with TruLens
import streamlit as st\nfrom trulens.core import TruSession\n\nfrom base import rag # a rag app with a query method\nfrom base import tru_rag # a rag app wrapped by trulens\n\nsession = TruSession()\n\ndef generate_and_log_response(input_text):\n with tru_rag as recording:\n response = rag.query(input_text)\n record = recording.get()\n return record, response\n\nwith st.form(\"my_form\"):\n text = st.text_area(\"Enter text:\", \"How do I launch a streamlit app?\")\n submitted = st.form_submit_button(\"Submit\")\n if submitted:\n record, response = generate_and_log_response(text)\n st.info(response)\n
With the record in hand, we can easily add TruLens components to display the evaluation results of the provided record using trulens_feedback. This will display the TruLens feedback result clickable pills as the feedback is available.
Display feedback results
from trulens.dashboard import streamlit as trulens_st\n\nif submitted:\n trulens_st.trulens_feedback(record=record)\n
In addition to the feedback results, we can also display the record's trace to help with debugging using trulens_trace from the TruLens streamlit module.
Display the trace
from trulens.dashboard import streamlit as trulens_st\n\nif submitted:\n trulens_st.trulens_trace(record=record)\n
Last, we can also display the TruLens leaderboard using render_leaderboard from the TruLens streamlit module to understand the aggregate performance across application versions.
Display the application leaderboard
from trulens.dashboard.leaderboard import render_leaderboard\n\nrender_leaderboard()\n
In combination, the streamlit components allow you to make evaluation front-and-center in your app. This is particularly useful for developer playground use cases, or to ensure users of app reliability.

It also shows the use of the dummy feedback function provider which behaves like the huggingface provider except it does not actually perform any network calls and just produces constant results. It can be used to prototype feedback function wiring for your apps before invoking potentially slow (to run/to load) feedback functions.

Now that we've ingested constructed the virtual records, we can build our feedback functions. This is done just the same as normal, except the context selector will instead refer to the new context_call we added to the virtual record.

We can do so with the TruLens guardrail, WithFeedbackFilterDocuments. All we have to do is use the method of_retriever to create a new filtered retriever, passing in the original retriever along with the feedback function and threshold we want to use.

Wouldn't it be great if we could automatically filter out context chunks with relevance scores below 0.5?
We can do so with the TruLens guardrail, WithFeedbackFilterNodes. All we have to do is use the method of_query_engine to create a new filtered retriever, passing in the original retriever along with the feedback function and threshold we want to use.

In addition to making informed iteration, we can also directly use feedback results as guardrails at inference time. In particular, here we show how to use the context relevance score as a guardrail to filter out irrelevant context before it gets passed to the LLM. This both reduces hallucination and improves efficiency.
To do so, we'll rebuild our RAG using the @context-filter decorator on the method we want to filter, and pass in the feedback function and threshold to use for guardrailing.

Guardrails play a crucial role in ensuring that only high quality output is produced by LLM apps. By setting guardrail thresholds based on feedback functions, we can directly leverage the same trusted evaluation metrics used for observability, at inference time.
Typical guardrails only allow decisions based on the output, and have no impact on the intermediate steps of an LLM application.
"},{"location":"trulens/guardrails/#trulens-guardrails-for-internal-steps","title":"TruLens guardrails for internal steps","text":"
While it is commonly discussed to use guardrails for blocking unsafe or inappropriate output from reaching the end user, TruLens guardrails can also be leveraged to improve the internal processing of LLM apps.
If we consider a RAG, context filter guardrails can be used to evaluate the context relevance of each context chunk, and only pass relevant chunks to the LLM for generation. Doing so reduces the chance of hallucination and reduces token usage.

Warning
Feedback function used as a guardrail must only return a float score, and cannot also return reasons.
TruLens has native python and framework-specific tooling for implementing guardrails. Read more about the available guardrails in native python, Langchain and Llama-Index.

This document highlights the changes required to move from trulens-eval to trulens.
The biggest change is that the trulens library now consists of several interoperable modules, each of which can be installed and used independently. This allows users to mix and match components to suit their needs without needing to install the entire library.
When running pip install trulens, the following base modules are installed:
trulens-core: core module that provides the main functionality for TruLens.
trulens-feedback: The module that provides LLM-based evaluation and feedback function definitions.
trulens-dashboard: The module that supports the streamlit dashboard and evaluation visualizations.
Furthermore, the following additional modules can be installed separately: - trulens-benchmark: provides benchmarking functionality for evaluating feedback functions on your dataset.
Instrumentation libraries used to instrument specific frameworks like LangChain and LlamaIndex are now packaged separately and imported under the trulens.apps namespace. For example, to use TruChain to instrument a LangChain app, run pip install trulens-apps-langchain and import it as follows:
from trulens.apps.langchain import TruChain\n
Similarly, providers are now packaged separately from the core library. To use a specific provider, install the corresponding package and import it as follows:
from trulens.providers.openai import OpenAI\n
To find a full list of providers, please refer to the API Reference.
As a result of these changes, the package structure for the TruLens varies from TruLens-Eval. Here are some common import changes you may need to make:

TruLens is a framework that helps you instrument and evaluate LLM apps including RAGs and agents.
Because TruLens is tech-agnostic, we offer a few different tools for instrumentation.
TruCustomApp gives you the most power to instrument a custom LLM app, and provides the instrument method.
TruBasicApp is a simple interface to capture the input and output of a basic LLM app.
TruChain instruments LangChain apps. Read more.
TruLlama instruments LlamaIndex apps. Read more.
TruRails instruments NVIDIA Nemo Guardrails apps. Read more.
In any framework you can track (and evaluate) the inputs, outputs and instrumented internals, along with a wide variety of usage metrics and metadata, detailed below:
Record ID (record_id) - automatically generated, track individual application calls
Timestamp (ts) - automatically tracked, the timestamp of the application call
Latency (latency) - the difference between the application call start and end time.
Using @instrument
from trulens.apps.custom import instrument\n\nclass RAG_from_scratch:\n @instrument\n def retrieve(self, query: str) -> list:\n \"\"\"\n Retrieve relevant text from vector store.\n \"\"\"\n\n @instrument\n def generate_completion(self, query: str, context_str: list) -> str:\n \"\"\"\n Generate answer from context.\n \"\"\"\n\n @instrument\n def query(self, query: str) -> str:\n \"\"\"\n Retrieve relevant text given a query, and then generate an answer from the context.\n \"\"\"\n
In cases you do not have access to a class to make the necessary decorations for tracking, you can instead use one of the static methods of instrument, for example, the alternative for making sure the custom retriever gets instrumented is via instrument.method. See a usage example below:
Using instrument.method
from trulens.apps.custom import instrument\nfrom somepackage.from custom_retriever import CustomRetriever\n\ninstrument.method(CustomRetriever, \"retrieve_chunks\")\n\n# ... rest of the custom class follows ...\n
Read more about instrumenting custom class applications in the API Reference
For basic tracking of inputs and outputs, TruBasicApp can be used for instrumentation.
Any text-to-text application can be simply wrapped with TruBasicApp, and then recorded as a context manager.
Using TruBasicApp to log text to text apps
from trulens.apps.basic import TruBasicApp\n\ndef custom_application(prompt: str) -> str:\n return \"a response\"\n\nbasic_app_recorder = TruBasicApp(\n custom_application, app_id=\"Custom Application v1\"\n)\n\nwith basic_app_recorder as recording:\n basic_app_recorder.app(\"What is the phone number for HR?\")\n
For frameworks with deep integrations, TruLens can expose additional internals of the application for tracking. See TruChain and TruLlama for more details.
TruLens provides TruChain, a deep integration with LangChain to allow you to inspect and evaluate the internals of your application built using LangChain. This is done through the instrumentation of key LangChain classes. To see a list of classes instrumented, see Appendix: Instrumented LangChain Classes and Methods.
In addition to the default instrumentation, TruChain exposes the select_context method for evaluations that require access to retrieved context. Exposing select_context bypasses the need to know the json structure of your app ahead of time, and makes your evaluations reusable across different apps.
To instrument an LLM chain, all that's required is to wrap it using TruChain.
Instrument with TruChain
from trulens.apps.langchain import TruChain\n\n# instrument with TruChain\ntru_recorder = TruChain(rag_chain)\n
To properly evaluate LLM apps we often need to point our evaluation at an internal step of our application, such as the retrieved context. Doing so allows us to evaluate for metrics including context relevance and groundedness.
For LangChain applications where the BaseRetriever is used, select_context can be used to access the retrieved text for evaluation.
TruChain also provides async support for LangChain through the acall method. This allows you to track and evaluate async and streaming LangChain applications.
As an example, below is an LLM chain set up with an async callback.
Create an async chain with LCEL
from langchain.callbacks import AsyncIteratorCallbackHandler\nfrom langchain.chains import LLMChain\nfrom langchain.prompts import PromptTemplate\nfrom langchain_openai import ChatOpenAI\nfrom trulens.apps.langchain import TruChain\n\n# Set up an async callback.\ncallback = AsyncIteratorCallbackHandler()\n\n# Setup a simple question/answer chain with streaming ChatOpenAI.\nprompt = PromptTemplate.from_template(\n \"Honestly answer this question: {question}.\"\n)\nllm = ChatOpenAI(\n temperature=0.0,\n streaming=True, # important\n callbacks=[callback],\n)\nasync_chain = LLMChain(llm=llm, prompt=prompt)\n
Once you have created the async LLM chain you can instrument it just as before.
Instrument async apps with TruChain
async_tc_recorder = TruChain(async_chain)\n\nwith async_tc_recorder as recording:\n await async_chain.ainvoke(\n input=dict(question=\"What is 1+2? Explain your answer.\")\n )\n
For examples of using TruChain, check out the TruLens Cookbook

More information about these decorators can be found in the docs/tracking/instrumentation/index.ipynb notebook.
The specific objects (of the above classes) and methods instrumented for a particular app can be inspected using the App.print_instrumented as exemplified in the next cell. Unlike Instrument.print_instrumentation, this function only shows what in an app was actually instrumented.
TruLens provides TruLlama, a deep integration with LlamaIndex to allow you to inspect and evaluate the internals of your application built using LlamaIndex. This is done through the instrumentation of key LlamaIndex classes and methods. To see all classes and methods instrumented, see Appendix: LlamaIndex Instrumented Classes and Methods.
In addition to the default instrumentation, TruLlama exposes the select_context and select_source_nodes methods for evaluations that require access to retrieved context or source nodes. Exposing these methods bypasses the need to know the json structure of your app ahead of time, and makes your evaluations reusable across different apps.
To instrument an Llama-Index query engine, all that's required is to wrap it using TruLlama.
Instrument a Llama-Index Query Engine
from trulens.apps.llamaindex import TruLlama\n\ntru_query_engine_recorder = TruLlama(query_engine)\n\nwith tru_query_engine_recorder as recording:\n print(query_engine.query(\"What did the author do growing up?\"))\n
To properly evaluate LLM apps we often need to point our evaluation at an internal step of our application, such as the retrieved context. Doing so allows us to evaluate for metrics including context relevance and groundedness.
For LlamaIndex applications where the source nodes are used, select_context can be used to access the retrieved text for evaluation.
Evaluating retrieved context for Llama-Index query engines
TruLlama also provides async support for LlamaIndex through the aquery, achat, and astream_chat methods. This allows you to track and evaluate async applications.
As an example, below is an LlamaIndex async chat engine (achat).
Instrument an async Llama-Index app
from llama_index.core import VectorStoreIndex\nfrom llama_index.readers.web import SimpleWebPageReader\nfrom trulens.apps.llamaindex import TruLlama\n\ndocuments = SimpleWebPageReader(html_to_text=True).load_data(\n [\"http://paulgraham.com/worked.html\"]\n)\nindex = VectorStoreIndex.from_documents(documents)\n\nchat_engine = index.as_chat_engine()\n\ntru_chat_recorder = TruLlama(chat_engine)\n\nwith tru_chat_recorder as recording:\n llm_response_async = await chat_engine.achat(\n \"What did the author do growing up?\"\n )\n\nprint(llm_response_async)\n
Just like with other methods, just wrap your streaming query engine with TruLlama and operate like before.
You can also print the response tokens as they are generated using the response_gen attribute.
Instrument a streaming Llama-Index app
tru_chat_engine_recorder = TruLlama(chat_engine)\n\nwith tru_chat_engine_recorder as recording:\n response = chat_engine.stream_chat(\"What did the author do growing up?\")\n\nfor c in response.response_gen:\n print(c)\n

This is done through the instrumentation of key NeMo Guardrails classes. To see a list of classes instrumented, see Appendix: Instrumented Nemo Classes and Methods.

The simplest method for logging with TruLens is by wrapping with TruChain as shown in the quickstart.
This is done like so:

Making the first call to your wrapped LLM Application will now also produce a log or \"record\" of the chain execution.
Following the request to your app, you can then evaluate LLM quality using feedback functions. This is completed in a sequential call to minimize latency for your application, and evaluations will also be logged to your local machine.
To get feedback on the quality of your LLM, you can use any of the provided feedback functions or add your own.
To assess your LLM quality, you can provide the feedback functions to session.run_feedback() in a list provided to feedback_functions.
In the above example, the feedback function evaluation is done in the same process as the chain evaluation. The alternative approach is the use the provided persistent evaluator started via session.start_deferred_feedback_evaluator. Then specify the feedback_mode for TruChain as deferred to let the evaluator handle the feedback functions.
For demonstration purposes, we start the evaluator here but it can be started in another process.

Snowflake\u2019s fully managed data warehouse provides automatic provisioning, availability, tuning, data protection and more\u2014across clouds and regions\u2014for an unlimited number of users and jobs.
TruLens can write and read from a Snowflake database using a SQLAlchemy connection. This allows you to read, write, persist and share TruLens logs in a Snowflake database.
Here is a guide to logging in Snowflake.

Connecting TruLens to a Snowflake database for logging traces and evaluations only requires passing in Snowflake connection parameters.

In some cases such as when using key-pair authentication, the SQL-alchemy URL does not support the credentials required. In this case, you can instead create and pass a database engine.
When the database engine is created, the private key is then passed through the connection_args.
Connect TruLens to Snowflake with a database engine
If your application was run (and logged) outside of TruLens, TruVirtual can be used to ingest and evaluate the logs.
+
This notebook walks through how to quickly log a dataframe of prompts, responses and contexts (optional) to TruLens as traces, and how to run evaluations with the trace data.
The dataframe should include minimally columns named query and response. You can also include a column named contexts if you wish to evaluate retrieval systems or RAGs.

Next, let's define feedback functions.
+
The add_dataframe method we plan to use will load the prompt, context and response into virtual records. We should define our feedback functions to access this data in the structure it will be stored. We can do so as follows:
+
+
prompt: selected using .on_input()
+
response: selected using on_output()
+
context: selected using VirtualApp.select_context()
+
+
+
+

We can then add the dataframe to TruLens using the virual recorder method add_dataframe. Doing so will immediately log the traces, and kick off the computation of evaluations. After some time, the evaluation results will be accessible both from the sdk (e.g. session.get_leaderboard) and in the TruLens dashboard.
+
If you wish to skip evaluations and only log traces, you can simply skip the sections of this notebook where feedback functions are defined, and exclude them from the construction of the virtual_recorder.
This notebook shows how to evaluate a custom streaming app.
+
It also shows the use of the dummy feedback function provider which
+behaves like the huggingface provider except it does not actually perform any
+network calls and just produces constant results. It can be used to prototype
+feedback function wiring for your apps before invoking potentially slow (to
+run/to load) feedback functions.
