🚀 Qwen2.5-VL-3B-Instruct
Qwen2.5-VL-3B-Instruct is a state - of - the - art vision - language model with enhanced visual understanding, agentic capabilities, and support for long - video analysis.
✨ Features
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.
Key Enhancements:
-
Understand things visually: Qwen2.5-VL is not only proficient in recognizing common objects such as flowers, birds, fish, and insects, but it is highly capable of analyzing texts, charts, icons, graphics, and layouts within images.
-
Being agentic: Qwen2.5-VL directly plays as a visual agent that can reason and dynamically direct tools, which is capable of computer use and phone use.
-
Understanding long videos and capturing events: Qwen2.5-VL can comprehend videos of over 1 hour, and this time it has a new ability of capturing events by pinpointing the relevant video segments.
-
Capable of visual localization in different formats: Qwen2.5-VL can accurately localize objects in an image by generating bounding boxes or points, and it can provide stable JSON outputs for coordinates and attributes.
-
Generating structured outputs: for data like scans of invoices, forms, tables, etc. Qwen2.5-VL supports structured outputs of their contents, benefiting usages in finance, commerce, etc.
Model Architecture Updates:
- 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.
We have three models with 3, 7 and 72 billion parameters. This repo contains the instruction - tuned 3B Qwen2.5-VL model. For more information, visit our Blog and GitHub.

📦 Installation
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'
🚀 Quick Start
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]==0.0.8
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.
💻 Usage Examples
Basic Usage
from transformers import Qwen2_5_VLForConditionalGeneration, AutoTokenizer, AutoProcessor
from qwen_vl_utils import process_vision_info
# default: Load the model on the available device(s)
model = Qwen2_5_VLForConditionalGeneration.from_pretrained(
"Qwen/Qwen2.5-VL-3B-Instruct", torch_dtype="auto", device_map="auto"
)
# We recommend enabling flash_attention_2 for better acceleration and memory saving, especially in multi-image and video scenarios.
# model = Qwen2_5_VLForConditionalGeneration.from_pretrained(
# "Qwen/Qwen2.5-VL-3B-Instruct",
# torch_dtype=torch.bfloat16,
# attn_implementation="flash_attention_2",
# device_map="auto",
# )
# default processer
processor = AutoProcessor.from_pretrained("Qwen/Qwen2.5-VL-3B-Instruct")
# The default range for the number of visual tokens per image in the model is 4-16384.
# You can set min_pixels and max_pixels according to your needs, such as a token range of 256-1280, to balance performance and cost.
# min_pixels = 256*28*28
# max_pixels = 1280*28*28
# processor = AutoProcessor.from_pretrained("Qwen/Qwen2.5-VL-3B-Instruct", min_pixels=min_pixels, max_pixels=max_pixels)

💡 Usage Tip
It's highly recommended to use the
[decord]
feature for faster video loading when installingqwen-vl-utils
. If you are not using Linux and can't installdecord
from PyPI, you can usepip install qwen-vl-utils
and fall back to using torchvision for video processing. You can also install decord from source to use it when loading videos.
