Reroute: Training-Free Visual Token Deferral Beats Rank-and-Remove in VLMs

June 9, 2026

Instead of permanently discarding low-ranked visual tokens, Reroute defers them to re-enter the candidate pool at later decoder layers, addressing the problem that token importance shifts across depth. The method is training-free and plug-in compatible with existing VLMs, targeting KV-cache memory and attention compute reduction.

HOW THIS AFFECTS YOU

●

builderYou can drop Reroute into existing VLM inference pipelines without retraining to reduce KV-cache memory pressure, particularly useful for grounding-heavy queries where token importance is query-dependent.

●

researcherThe empirical finding that visual token importance varies across decoder depth challenges the assumptions of most existing token pruning methods and motivates the recoverable routing design.
