CONF-KV Uses Per-Step Confidence Scores to Dynamically Manage KV Cache
May 23, 2026
CONF-KV adapts KV cache budget at each decoding step using a scalar confidence score derived from the next-token distribution, retaining more context when model uncertainty is high and pruning aggressively when confident. It combines attention-mass and recency ranking with a protected recent window, using blockwise online-softmax attention for memory efficiency in long-horizon inference.

HOW THIS AFFECTS YOU
●
builderYou can potentially reduce GPU memory pressure in long-context LLM deployments without fixed eviction windows, though this is research-stage with no released implementation cited.

researcherThe confidence-driven dynamic budget is a novel signal for cache eviction that outperforms static recency or historical attention baselines — worth examining for long-context architectures.
