In the past five months since Qwen2-VL's release, numerous developers have built new models on the Qwen2-VL vision-language models, providing us with valuable feedback. During this period, we focused on building more useful vision-language models. Today, we are excited to introduce the latest addition to the Qwen family: Qwen2.5-VL.
-
Powerful Document Parsing Capabilities: Upgrade text recognition to omnidocument parsing, excelling in processing multi-scene, multilingual, and various built-in (handwriting, tables, charts, chemical formulas, and music sheets) documents.
-
Precise Object Grounding Across Formats: Unlock improved accuracy in detecting, pointing, and counting objects, accommodating absolute coordinate and JSON formats for advanced spatial reasoning.
-
Ultra-long Video Understanding and Fine-grained Video Grounding: Extend native dynamic resolution to the temporal dimension, enhancing the ability to understand videos lasting hours while extracting event segments in seconds.
-
Enhanced Agent Functionality for Computer and Mobile Devicess: Leverage advanced grounding, reasoning, and decision-making abilities, boosting the model with superior agent functionality on smartphones and computers.
- Dynamic Resolution and Frame Rate Training for Video Understanding:
We extend dynamic resolution to the temporal dimension by adopting dynamic FPS sampling, enabling the model to comprehend videos at various sampling rates. Accordingly, we update mRoPE in the time dimension with IDs and absolute time alignment, enabling the model to learn temporal sequence and speed, and ultimately acquire the ability to pinpoint specific moments.
- Streamlined and Efficient Vision Encoder
We enhance both training and inference speeds by strategically implementing window attention into the ViT. The ViT architecture is further optimized with SwiGLU and RMSNorm, aligning it with the structure of the Qwen2.5 LLM.

Below, we provide simple examples to show how to use Qwen2.5-VL with 🤖 ModelScope and 🤗 Transformers.
The code of Qwen2.5-VL has been in the latest Hugging face transformers and we advise you to build from source with command:
pip install git+https://github.com/huggingface/transformers accelerate
or you might encounter the following error:
KeyError: 'qwen2_5_vl'
We offer a toolkit to help you handle various types of visual input more conveniently, as if you were using an API. This includes base64, URLs, and interleaved images and videos. You can install it using the following command:
# It's highly recommanded to use `[decord]` feature for faster video loading.
pip install qwen-vl-utils[decord]If you are not using Linux, you might not be able to install decord from PyPI. In that case, you can use pip install qwen-vl-utils which will fall back to using torchvision for video processing. However, you can still install decord from source to get decord used when loading video.
We are preparing cookbooks for many capabilities, including recognition, localization, document parsing, video understanding, key information extraction, and more. Welcome to learn more!

print(output_texts)We strongly advise users especially those in mainland China to use ModelScope. snapshot_download can help you solve issues concerning downloading checkpoints.
For input images, we support local files, base64, and URLs. For videos, we currently only support local files.

]The model supports a wide range of resolution inputs. By default, it uses the native resolution for input, but higher resolutions can enhance performance at the cost of more computation. Users can set the minimum and maximum number of pixels to achieve an optimal configuration for their needs, such as a token count range of 256-1280, to balance speed and memory usage.
min_pixels = 256 * 28 * 28
max_pixels = 1280 * 28 * 28
processor = AutoProcessor.from_pretrained(
"Qwen/Qwen2.5-VL-7B-Instruct", min_pixels=min_pixels, max_pixels=max_pixels
)Besides, We provide two methods for fine-grained control over the image size input to the model:
-
Specify exact dimensions: Directly set
resized_heightandresized_width. These values will be rounded to the nearest multiple of 28. -
Define min_pixels and max_pixels: Images will be resized to maintain their aspect ratio within the range of min_pixels and max_pixels.
# resized_height and resized_width
messages = [
{
"role": "user",
"content": [
{
"type": "image",
"image": "file:///path/to/your/image.jpg",
"resized_height": 280,
"resized_width": 420,
},
{"type": "text", "text": "Describe this image."},

},
{"type": "text", "text": "Describe this image."},
],
}
]By default, images and video content are directly included in the conversation. When handling multiple images, it's helpful to add labels to the images and videos for better reference. Users can control this behavior with the following settings:
Add vision ids

pip install -U flash-attn --no-build-isolationAlso, you should have a hardware that is compatible with Flash-Attention 2. Read more about it in the official documentation of the flash attention repository. FlashAttention-2 can only be used when a model is loaded in torch.float16 or torch.bfloat16.
To load and run a model using Flash Attention-2, simply add attn_implementation="flash_attention_2" when loading the model as follows:
from transformers import Qwen2_5_VLForConditionalGeneration
model = Qwen2_5_VLForConditionalGeneration.from_pretrained(
"Qwen/Qwen2.5-VL-7B-Instruct",
torch_dtype=torch.bfloat16,
attn_implementation="flash_attention_2",
)The current config.json is set for context length up to 32,768 tokens.
To handle extensive inputs exceeding 32,768 tokens, we utilize YaRN, a technique for enhancing model length extrapolation, ensuring optimal performance on lengthy texts.
For supported frameworks, you could add the following to config.json to enable YaRN:
{
...,
"type": "yarn",
"mrope_section": [
16,
24,
24
],
"factor": 4,
"original_max_position_embeddings": 32768
}
However, it should be noted that this method has a significant impact on the performance of temporal and spatial localization tasks, and is therefore not recommended for use.
At the same time, for long video inputs, since MRoPE itself is more economical with ids, the max_position_embeddings can be directly modified to a larger value, such as 64k.
To explore Qwen2.5-VL-72B, a more fascinating multimodal model, we encourage you to test our cutting-edge API service. Let's start the exciting journey right now!
pip install dashscopeimport dashscope
dashscope.api_key = "your_api_key"
messages = [{
'role': 'user',
'content': [
{
'image': "https://dashscope.oss-cn-beijing.aliyuncs.com/images/dog_and_girl.jpeg"
},
{
'text': 'What are in the image?'
},
]
}]
response = dashscope.MultiModalConversation.call(model='qwen2.5-vl-72b-instruct', messages=messages)
print(response)For more usage, please refer to the tutorial at aliyun.
In this section, we provide instructions for users to build a web-based user interface (UI) demo. This UI demo allows users to interact with a predefined model or application through a web browser. Follow the steps below to get started.
Before you begin, ensure that you have the required dependencies installed on your system. You can install them by running the following command:
pip install -r requirements_web_demo.txtOnce the required packages are installed, you can launch the web demo using the following command. This command will start a web server and provide you with a link to access the UI in your web browser.
Recommended: For enhanced performance and efficiency, especially in multi-image and video processing scenarios, we strongly recommend using FlashAttention-2. FlashAttention-2 provides significant improvements in memory usage and speed, making it ideal for handling large-scale models and data processing.
To enable FlashAttention-2, use the following command:
python web_demo_mm.py --flash-attn2This will load the model with FlashAttention-2 enabled.
Default Usage: If you prefer to run the demo without FlashAttention-2 or if you do not specify the --flash-attn2 option, the demo will load the model using the standard attention implementation:
python web_demo_mm.pyAfter running the command, you’ll see a link generated in the terminal similar to this:
Running on local: http://127.0.0.1:7860/
Copy this link and paste it into your browser to access the web UI, where you can interact with the model by inputting text, uploading images, or using any other provided functionalities.
An experimental streaming video chat demo is also available in the web_demo_streaming directory.
To run the streaming video chat demo, use the following command:
cd web_demo_streaming/
python app.py --flash-attn2If you prefer to run the demo without FlashAttention-2, use the following command:
cd web_demo_streaming/
python app.pyThis demo supports webcam/screen capture as its video input source. To support screen capture video input, we use code snippet from the following hugginface space: gstaff/gradio-screen-recorder.
To simplify the deploy process, we provide docker images with pre-build environments: qwenllm/qwenvl. You only need to install the driver and download model files to launch demos.
docker run --gpus all --ipc=host --network=host --rm --name qwen2 -it qwenllm/qwenvl:2-cu121 bashIf you find our paper and code useful in your research, please consider giving a star ⭐ and citation 📝 :)
