PROBLEMLong-horizon LLM inference strains GPU memory due to the growing KV cache, making attention computation per token prohibitively expensive. Existing eviction policies ignore the model’s real-time uncertainty, a valuable yet unused signal.
APPROACHCONF-KV dynamically evicts low-impact KV pairs by monitoring confidence (uncertainty) in the next-token distribution, computed via entropy or top-p probabilities. It combines this with mixed-precision storage, retaining high-confidence pairs in FP16 and demoting others to INT8, reducing memory without significant accuracy loss. The eviction strategy prioritizes high-utility tokens based on confidence and recency.
KEY RESULTSOn 16K-token sequences, CONF-KV cuts GPU memory by 35% versus baseline (FP16-only), with <1% drop in accuracy on LM tasks. Mixed-precision storage alone reduces memory by 21%.
BUILDERS TAKEAWAYImplement confidence-based eviction for KV caches in long-context applications (e.g., document QA, code generation). Start by measuring per-layer entropy during decoding and experiment with INT8 for low-confidence tokens to reduce memory overhead.
LIMITATIONSConfidence thresholds require task-specific tuning, and eviction may degrade performance in highly uncertain, long-tail scenarios.
