VerifiedIn the Prompt Cache mechanism, when the prefix content of an API request is identical to a previous one, the system reuses the already-computed KV cache to complete cache reads at a lower price, while cache write is the billing item for the first time content is written into the cache.74% similarUnverifiedRemote Cache extends the build caching mechanism to the team level, enabling build caches to be shared across different developers or CI nodes.72% similarUnverifiedCaching means pre-storing recurring system prompts or long documents so that subsequent requests reuse them at a lower unit price, suitable for multi-turn Q&A or fixed knowledge base scenarios.72% similarVerifiedThe core principle of prompt caching is cross-request reuse of the KV Cache, where already-computed KV states can be cached and reused when multiple requests share the same prefix.70% similarUnverifiedA prompt cache hit requires the request prefix to be byte-for-byte identical to what was written at cache time; mixing dynamic content such as timestamps or session IDs into system prompts will cause frequent cache invalidation.68% similar
