TRIO: Token Reduction via Inference-Objective Guidance for Efficient Vision-Language Models

Congyang Ou, Dawei Yan, Haokui Zhang, Peng Wang, Qingsen Yan, Rong Xiao, Ying Li, Yu Zhang

TRIO reduces visual tokens in vision-language models to 11 percent while retaining 97 percent performance by selecting tokens whose removal leaves the final output unchanged.

The bundle contains the canonical record plus signed events. A mirror can host it anywhere and recompute the same current state with the deterministic merge algorithm.

Claims

C1strongest claim

On LLaVA-Next-7B, TRIO retains just 11.1% of visual tokens but maintains 97.2% of the original performance, with a 2.75× prefill speedup, 2.14× inference speedup, 6.22× lower FLOPs, and 6.05× reduced KV Cache overhead.

C2weakest assumption

That the designed layer-local proxy loss produces token-level gradient saliency that reliably identifies tokens whose removal leaves the final output essentially unchanged, without requiring full end-to-end gradients or task-specific tuning.

C3one line summary

TRIO keeps 97.2% performance on LLaVA-Next-7B using only 11.1% visual tokens, yielding 2.75x prefill speedup and 6x lower FLOPs via inference-objective gradient guidance.
