UnverifiedTraditional inference frameworks pre-allocate contiguous KV Cache memory blocks for each concurrent request, resulting in severe memory fragmentation and low utilization.76% similarUnverifiedKV cache reuses the Key and Value matrices of historical tokens during the inference phase, avoiding repeated attention computation on already-generated sequences.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.72% similarUnverifiedKV 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.72% similarUnverifiedKV caching reduces the attention computation complexity from quadratic to linear growth by caching the Key and Value vectors of historical tokens.71% similar
