ResKV: Recovering Evicted Token Contributions via Residual KV Cache — LongBench 32/32
Article summary
Quick briefing — cleaned from the original RSS feed
TL;DR KV cache eviction permanently throws away tokens. KV cache merging corrupts the values of surviving tokens. ResKV (arXiv:2607.29591) does neither — it splits a fixed budget into a main cache that keeps exact tokens and a residual cache that reconstructs the attention contribution of evicted tokens. Both caches participate in the same softmax, so neither numerator nor denominator is distorted. Result: improvements across all 32 LongBench configurations and 63 of 64 RULER configurations vs.…
