VisionZip: Longer is Better but Not Necessary in Vision Language Models

Summary

The paper introduces VisionZip, a method to improve the efficiency of vision-language models (VLMs) by reducing redundancy in visual tokens. The authors observe that existing VLMs use excessively long visual token sequences, leading to high computational costs. VisionZip selects informative tokens, significantly improving inference speed and maintaining or even exceeding performance compared to state-of-the-art methods. The technique is applicable to various tasks, including multi-turn dialogues, and is shown to be effective across multiple VLM architectures. The paper also analyzes the causes of redundancy in visual tokens, highlighting the limitations of existing text-based token selection methods.
