Project Overview
Qwen2-VL is the latest version in the series of large multimodal language models developed by the Alibaba Cloud Qwen team. This project leverages advanced visual language modeling techniques to provide deep understanding of images across various resolutions and aspect ratios, as well as real-time processing of videos longer than 20 minutes.
Not only can Qwen2-VL process images and videos, but it also has the capability to interact with mobile devices and robots. It supports multilingual environments, recognizing text in various languages within images. This makes it suitable for high-quality visual question answering, dialogue, and content creation tasks.
Main Features
- State-of-the-Art Image Understanding: Qwen2-VL achieves top performance on visual understanding benchmarks, including MathVista, DocVQA, RealWorldQA, and MTVQA.
- Video Understanding Beyond 20 Minutes: With its online streaming capabilities, Qwen2-VL can comprehend videos longer than 20 minutes, facilitating high-quality video-based question answering, dialogue, and content creation.
- Operational Integration with Devices: Qwen2-VL can operate mobile devices and robots through complex reasoning and decision-making, automatically responding to visual environments and textual commands.
- Multilingual Support: To cater to a global audience, Qwen2-VL understands not only English and Chinese but also various languages including most European languages, Japanese, Korean, Arabic, and Vietnamese.
Architecture
Dynamic Resolution Handling: Unlike previous models, Qwen2-VL can process images of any resolution, mapping them to a dynamic number of visual tokens, which enhances the human-like visual processing experience.
Multimodal Rotary Position Embedding (M-ROPE): This feature decomposes positional embeddings into multiple parts, capturing 1D text, 2D visuals, and 3D video positional information, thereby enhancing its multimodal processing capabilities.
Benchmark Performance
Image Benchmarks: Qwen2-VL has been tested against various benchmarks, showcasing its superior capabilities in understanding images.
Video Benchmarks: The model excels in video comprehension, demonstrating its ability to analyze and respond to video content effectively.
Agent Benchmarks: Qwen2-VL performs well in tasks requiring interaction with devices, showcasing its operational capabilities.
Multilingual Benchmarks: The model has been evaluated for its multilingual understanding, proving its versatility in processing different languages.

What makes Qwen2-VL unique compared to other vision-language models?
Qwen2-VL stands out for its ability to understand videos longer than 20 minutes, achieving state-of-the-art performance on video comprehension benchmarks like MTVQA. It also supports multilingual text understanding from images across a wide range of languages, including European, Asian, and Middle Eastern languages.
How does Qwen2-VL’s architecture enable long-form video understanding?
Qwen2-VL uses a novel architecture called Multimodal Rotary Position Embedding (M-ROPE) that decomposes positional embeddings to capture 1D textual, 2D visual, and 3D video positional information. This allows it to maintain continuous understanding of video content, similar to how humans process information.
What are the key performance advantages of Qwen2-VL compared to other models?
Qwen2-VL outperforms leading models like GPT-4 and Claude 3.5 across a range of benchmarks, particularly in complex reasoning, mathematical ability, document understanding, multilingual comprehension, and video understanding. The open-source Qwen2-VL-72B model demonstrates the strongest performance.
