Summary
The Braintrust Go SDK instruments OpenAI, Anthropic, Google GenAI, sashabaranov/go-openai, LangChainGo, Firebase Genkit, Google ADK, CloudWeGo Eino, and AWS Bedrock — but does not instrument the Azure OpenAI standalone Go SDK (github.com/Azure/azure-sdk-for-go/sdk/ai/azopenai). Azure is explicitly listed as a supported provider in Braintrust's tracing documentation, yet there is no SDK-level instrumentation wrapper for Go in this repository.
Importantly, azopenai is a standalone client — it does not use openai-go under the hood. It has its own Client type and its own HTTP transport, so the existing trace/contrib/openai middleware (which hooks into openai-go via option.WithMiddleware()) does not cover azopenai calls.
What is missing
A trace/contrib/azopenai/ integration module that wraps execution calls on the azopenai Go client. The key execution surfaces are:
GetChatCompletions / GetChatCompletionsStream — conversational model inference (non-streaming and streaming), including tool use and structured outputsGetEmbeddings — vector embedding generationGetCompletions / GetCompletionsStream — legacy text completions
The azopenai client supports both Azure Active Directory (via azidentity) and API key authentication, with Azure-specific endpoints and API versions. Instrumentation could wrap the client's http.Client (similar to the genai integration pattern) or use Azure SDK pipeline middleware hooks.
Braintrust docs status
supported — Braintrust explicitly lists Azure as a supported provider for tracing:
"OpenAI, Anthropic, Gemini, AWS Bedrock, Azure, Mistral, Together, Groq, and many more"
Source: https://www.braintrust.dev/docs/guides/tracing and https://www.braintrust.dev/docs/instrument
Azure OpenAI Service is also acknowledged in the Braintrust AI provider configuration docs. However, there is no Go SDK-level tracing wrapper for azopenai in this repository.
