UnverifiedThe prompt caching mechanism of language models caches previously sent messages, eliminating the need to repeatedly reprocess the same content.79% similarUnverifiedPrefix caching improves inference efficiency by caching common prompt prefixes to reduce redundant computation.79% 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.74% similarUnverifiedPrompt caching technology stores KV matrices in high-speed memory, and when the next request contains the same prefix content, it reads directly from the cache, skipping recomputation.72% 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.72% similar
