Prompt Caching allows you to cache large, stable portions of input (such as long documents, background information, system instructions, etc.).
This way, subsequent requests with unchanged content can directly reuse the cache, avoiding repeated processing, significantly improving response speed, and saving costs. It is suitable for scenarios like multi-turn conversations, long document analysis, and batch Q&A.
When to Consider Using It
Similar to caching strategies like Redis, prompt caching is recommended when there is a large amount of reusable context.
Unlike typical caching, prompt caching prefers long content, as cache reads cost only 10% of the base input cost.
