Researchers have developed GSTEP, a novel pruning framework designed to enhance the efficiency of Video Large Language Models (VideoLLMs). Unlike previous methods that prune tokens locally within segments, GSTEP models videos as a continuous spatio-temporal information flow. It calculates a token-level density by combining temporal and spatial information, enabling global token sampling that balances information density and coverage. Experiments show GSTEP can prune a significant portion of visual tokens while maintaining high performance, leading to improved accuracy-efficiency trade-offs across different models and settings. AI
