Anthropic 的 Claude 引入提示缓存以减少冗余处理

Anthropic 为其 Claude 模型引入了提示缓存功能,旨在减少多轮对话中相同提示前缀的冗余处理。该机制允许 API 重用提示中先前已处理的部分,例如系统指令或工具定义,而不是在每次新请求时重新分析它们。用户可以自动启用此功能或通过显式断点启用,缓存的写入和读取会产生相关费用,并且缓存生效需要满足最小提示长度要求。 AI

影响 降低了在 Claude 上构建多轮应用程序的开发者的运营成本,可能增加采用率。

    提示缓存,解释:Claude 如何重用您的提示前缀 — 以及何时它不划算

    <p>If you build anything that talks to Claude more than once — a chatbot, a coding agent, a document Q&amp;A tool — you are probably paying to process the same text over and over again. Every API request is stateless: the model re-reads your system prompt, your tool definitions, …
