UnverifiedPrompt Caching is an optimization across requests, users, and conversations: as long as the prompt prefixes of different requests are completely identical, the corresponding KV results can be shared globally.77% similarUnverifiedPrompt Caching refers to LLM service providers caching repeatedly occurring prefix content in requests, with cache hits reducing computational cost and latency.76% similarUnverifiedCommon guardrail implementations include input filtering, system prompt constraints, output moderation, and retrieval-augmented generation (RAG).69% similarUnverifiedTypical scenarios that benefit from prefix caching include multi-turn conversations sharing the same system prompt, repeated document contexts in RAG, and stable codebase prefixes in code completion.68% similarUnverifiedPrompt Caching通过复用相同前缀内容的Key和Value矩阵来降低推理成本，Agent类应用因高频迭代和长上下文交互天然适合缓存优化68% similar
