UnverifiedConventional KV caching is an optimization within a single request: within the same conversation round, the KV generated from historical messages does not need to be recomputed, and only the newly input content is computed incrementally.70% similarVerifiedKV Cache通过将已计算的键值对持久化存储，使相同Prompt前缀的后续请求可直接复用，跳过重复的矩阵运算68% similarUnverifiedAgent类应用因每轮对话携带几乎相同的系统提示词和追加历史记录，前缀重叠率高，天然适合缓存优化以降低成本67% similarVerifiedThe core principle of prompt caching is cross-request reuse of the KV Cache, where already-computed KV states can be cached and reused when multiple requests share the same prefix.65% similarUnverifiedIn distributed inference scenarios, components such as the scheduler, executor, and KV Cache manager collaborate across processes or nodes, relying on stable protocol formats to exchange messages.65% similar
