Context Caching is a billing optimization mechanism provided by model vendors; when multiple requests share the same long prefix, cache breakpoints can be marked to reuse the already-computed KV Cache, billed at a lower unit price and reducing first-token latency.

UnverifiedPrompt Caching refers to LLM service providers caching repeatedly occurring prefix content in requests, with cache hits reducing computational cost and latency.79% similarUnverifiedPrompt Caching is a mechanism provided by large-model service providers such as the Anthropic API: when the request prefix is exactly the same as that of a previous request, the server reuses the already-computed KV Cache, the cache-hit portion is billed at 0.1 times the input price, and the first cache write is billed at 1.25 times.77% similarUnverifiedPrefix Cache optimization refers to the API server's ability to cache the KV computation results of an unchanged system prompt prefix across multi-turn conversations for reuse by subsequent requests, reducing redundant computation and lowering latency and token costs.74% similarVerifiedThe caching mechanism is technically commonly referred to as KV Cache or Prompt Caching74% similarUnverifiedThe Context Caching technology provided by Anthropic allows previously processed context prefixes to be reused, reducing repetitive computation costs in multi-turn conversations.74% similar
