Researchers have developed TOPS, a novel method for pruning visual tokens in multimodal large language models (MLLMs) to improve efficiency. Unlike previous approaches that relied on attention scores or token similarity, TOPS uses a first-principles, information-theoretic framework to identify essential tokens based on task relevance, information coverage, and semantic diversity. This training-free and model-agnostic module has demonstrated significant performance improvements across various MLLMs, notably reducing visual tokens by over 77% on LLaVA-NeXT while maintaining or even slightly improving performance.
