UnverifiedKV感知路由通过维护“哪个节点缓存了哪段上下文”的索引,把新请求优先导向已持有相关KV的节点,从而复用缓存、跳过重复prefill;但KV缓存需要在节点间迁移或复制,路由决策失准会使命中率下降、收益迅速消失。65% 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.65% similarUnverifiedEvicting the KV entries of low-value tokens has become a key means of reducing the cost of long-context inference.64% similarUnverifiedKV caching reduces the attention computation complexity from quadratic to linear growth by caching the Key and Value vectors of historical tokens.62% similarUnverifiedEach agent instance requires a certain amount of KV cache VRAM, and when the concurrency exceeds the VRAM capacity it causes OOM (out-of-memory) errors.62% similar
