Researchers have developed several new methods to efficiently prune visual tokens for multimodal large language models (MLLMs), aiming to reduce inference costs and latency. The LAST framework uses the last query token's attention to guide pruning without needing access to the cloud model, preserving 95.4% of accuracy while reducing tokens by 87.5%. SFPruner reformulates pruning into a single forward pass, significantly cutting token selection time from 112.4 ms to 2.5 ms for Qwen2.5-VL. SPARE, another approach, treats pruning as subspace reconstruction, removing up to 94% of tokens while maintaining 95% of baseline performance on LLaVA by minimizing reconstruction error and incorporating an 'anti-relevance' criterion.
