CatchUp: Depth-Aware Re-Admission of Visual Tokens for Efficient Large Vision-Language Models

CatchUp is a training‑free framework that improves efficiency in large vision‑language models by depth‑aware re‑admission of visual tokens. It repeatedly evaluates query‑conditioned relevance, processes only selected tokens per decoder interval, and preserves deferred tokens for later re‑admission, using reference‑to‑current transition signals to approximate missed representation evolution. Experiments on three referring‑expression grounding datasets and six multimodal benchmarks show that CatchUp retains over 92% of full‑model performance with 88.9% fewer active tokens and reduces end‑to‑end latency by 8.0% at a 64‑token budget.

LearnPrunerV2: Learnable Progressive Token Pruning for Vision-Language Models

LearnPrunerV2 is a fully learnable token‑pruning framework for Vision‑Language Models that replaces heuristic pruning with lightweight modules in every backbone layer. These modules estimate token importance by combining visual saliency and query relevance via a shadow token, revealing a consistent staircase redundancy pattern across layers. The method introduces Budget‑Deterministic Pruning to set fixed per‑layer budgets, achieving state‑of‑the‑art efficiency while preserving 99.8% of performance even after pruning 77.8% of visual tokens on LLaVA‑v1.5.

LearnPrunerV2: Learnable Progressive Token Pruning for Vision-Language Models

LearnPrunerV2 introduces a fully learnable token pruning framework for Vision‑Language Models, embedding lightweight modules in every backbone layer to estimate token importance by combining visual saliency and query relevance via a shadow token. It identifies a consistent staircase redundancy pattern across layers and employs Budget‑Deterministic Pruning to set fixed per‑layer budgets, yielding a hardware‑friendly pruning schedule. Experiments show that LearnPrunerV2 outperforms prior methods, preserving 99.8% of performance while removing 77.8% of visual tokens on LLaVA‑v1.5, thus achieving a superior accuracy‑efficiency trade‑off.
