The KV Cache mechanism reduces token costs in long-context, high-frequency-call scenarios by reusing already-computed intermediate results to avoid re-executing forward inference on the same text.

VerifiedThe KV Cache mechanism can cache repeated prefix content, and the more concise the system prompt, the higher the cache hit rate.79% similarUnverifiedPrefix caching improves inference efficiency by caching common prompt prefixes to reduce redundant computation.77% similarUnverifiedCache Read refers to the model directly reading intermediate computation results of already-parsed context from cache during multi-turn conversations or repeated calls, without needing to reprocess.76% 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.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% similar
