Alibaba Cloud, the digital technology and intelligence backbone of Alibaba Group, has launched two open-source large vision language models (LVLM), Qwen-VL and its conversationally fine-tuned Qwen-VL-Chat. The models can comprehend images, texts and bounding boxes in prompts and facilitate multi-round question answering in both English and Chinese.
Qwen-VL is the multimodal version of Qwen-7B, Alibaba Cloud’s 7-billion-parameter model of its large language model Tongyi Qianwen (also available on ModelScope as open-source). Capable of understanding both image inputs and text prompts in English and Chinese, Qwen-VL can perform various tasks such as responding to open-ended queries related to different images and generating image captions.
Qwen-VL-Chat caters to more complex interaction, such as comparing multiple image inputs and engaging in multi-round question answering. Leveraging alignment techniques, this AI assistant exhibits a range of creative capabilities, which include writing poetry and stories based on input images, summarising the content of multiple pictures, and solving mathematical questions displayed in images.
Contribution to open source and inclusivity
In a bid to democratise AI technologies, Alibaba Cloud has shared the model’s code, weights, and documentation with academics, researchers, and commercial institutions worldwide. This contribution to the open-source community is accessible via Alibaba’s AI model community ModelScope and the collaborative AI platform Hugging Face. For commercial uses, companies with over 100 million monthly active users can request a licence from Alibaba Cloud.
The introduction of these models, with their ability to extract meaning and information from images, holds the potential to revolutionise the interaction with visual content. For instance, leveraging its image comprehension and question answering capability, the models could provide information assistance to visually impaired individuals during online shopping in the future.
The Qwen-VL model was pre-trained on image and text datasets. Compared to other open-source large vision language models that can process and understand images in 224*224 resolution, Qwen-VL can handle image input at a resolution of 448*448, resulting in better image recognition and comprehension.
Based on various benchmarks, Qwen-VL recorded outstanding performances on several visual language tasks, including zero-shot captioning, general visual question answering, text-oriented visual question answering and object detection.
Qwen-VL-Chat has also achieved leading results in both Chinese and English for text-image dialogue and alignment levels with humans, according to the benchmark test of Alibaba Cloud. This test involved over 300 images, 800 questions, and 27 categories.
Earlier this month, Alibaba Cloud open sourced its 7-billion-parameter LLMs, Qwen-7B and Qwen-7B-Chat as its ongoing contribution to the open-source community. The two models have had over 400,000 downloads within a month of their launch.
