For scenarios with highly stable prefixes and dense calls, prefer explicit caching; for scenarios with variable prefixes and sporadic calls, the zero-modification advantage of automatic caching is more practical.

UnverifiedWhen inputs are small and well-defined (such as a fixed set of topics, file extension lists, or status codes), switch nodes or regular expressions should be used instead of models, achieving zero randomness without consuming GPU resources.71% similarUnverifiedPrefix caching improves inference efficiency by caching common prompt prefixes to reduce redundant computation.71% similarUnverifiedPrompt caching takes effect in units of "prefix" and only works for content that is completely identical from the start; once a token in the middle changes, the content after it cannot hit the existing cache.67% similarUnverifiedKun通过将稳定不变内容置于Prompt前缀、动态对话内容置于末尾来最大化缓存复用率67% similarVerifiedThe KV Cache mechanism can cache repeated prefix content, and the more concise the system prompt, the higher the cache hit rate.66% similar
