Common optimization directions for KV Cache include low-precision quantization (such as FP8 and INT8), evicting or sparsely retaining historical tokens, managing the cache by page, and reusing it via prefix caching.

UnverifiedKV Cache reduces inference computational complexity from O(n²) to O(n) by caching and reusing the Key and Value vectors of historical tokens; if the cache is incorrectly truncated, overwritten, or subject to cross-session interference, it causes context confusion and triggers loops.77% similarUnverifiedEvicting the KV entries of low-value tokens has become a key means of reducing the cost of long-context inference.77% similarUnverifiedThe dynamic sparse KV-cache approach dynamically evaluates which historical positions are truly important for the current generation, pruning or storing at reduced precision the cache entries with low contribution, keeping only a sparse but critical subset.75% similarVerifiedIn the KV Cache mechanism, reusing cached KV values is a cache hit, while context changes that invalidate the cache and require recomputation are a cache miss.74% similarUnverifiedKV caching reduces the attention computation complexity from quadratic to linear growth by caching the Key and Value vectors of historical tokens.70% similar
