Researchers have developed CoverPrune, a novel framework for pruning tokens in 3D Vision-Language Models (3D VLMs) to address computational bottlenecks. Unlike previous methods that focused on token diversity, CoverPrune prioritizes preserving visual evidence coverage by formulating token pruning as an Optimal Transport problem. The framework includes an efficient Spatial-Guided Greedy Selection algorithm and an accelerated variant, CoverPrune-Lite, which together achieve state-of-the-art token efficiency while maintaining robust reasoning performance on 3D benchmarks.
