UnverifiedAnthropic需要在消息中添加cache_control字段来标记缓存断点，告诉API哪些内容应被缓存62% similarUnverifiedA cache hit means the model server recognizes that the prefix of the current request highly overlaps with a previous request, and directly reuses the already-computed KV cache without re-running inference, thereby reducing the actual computation load.58% similarUnverifiedThe non-determinism in tool call ordering causes cache keys based on request body hashes to identify functionally identical requests as different requests, resulting in cache misses.57% similarUnverified可通过API返回的cache_hit_tokens等字段核实缓存是否真正命中56% 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.55% similar
