Prompt Caching supports only prefix matching, and only repeated content placed at the very front can be reused; in engineering practice one should follow the principle of fixed content first and dynamic content last.

UnverifiedPrompt cache hits rely on strict prefix matching; any change to earlier content will affect the reuse of subsequent content.76% similarUnverifiedPrompt caching can avoid repeated charges for identical prefixes, because system prompts and retrieved document fragments tend to be highly repetitive across multiple conversation turns.74% similarUnverifiedSemantic caching technology assesses the semantic similarity between a new query and historical queries, and when the condition is met, directly returns the cached result to avoid redundant computation.68% 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% similarUnverifiedWhen multimodal content intersects with the prefix caching mechanism, cache entries may be partially overwritten by the prefix, leading to data reference confusion or state inconsistency.66% similar
