Researchers have developed VIP-Router, a novel system designed to optimize the efficiency of multimodal large language models (MLLMs) by adaptively selecting the best vision token pruning strategy for each input. Unlike previous methods that applied a single strategy across all inputs, VIP-Router analyzes low-cost visual and textual features to predict which pruning approach will yield the highest accuracy and utility. This plug-and-play solution integrates seamlessly with existing MLLMs and pruning algorithms, introducing minimal trainable parameters. Evaluations on the VTC-Bench Group A benchmark demonstrated that VIP-Router significantly outperforms fixed-strategy baselines, achieving a 26.9% relative improvement in average accuracy and a 22.0% relative increase in average utility.
