系统提示

查看 claude.ai、Claude iOS 应用和 Claude Android 应用上核心系统提示的更新。

Claude 的网页界面(claude.ai)和移动应用使用系统提示在每次对话开始时向 Claude 提供最新信息,例如当前日期。系统提示还会鼓励某些行为,例如始终以 Markdown 格式提供代码片段。此提示会定期更新以改进 Claude 的响应。这些系统提示更新不适用于 Claude API。如果某个模型在下方有多个带日期的条目,则各版本之间的更新内容会以粗体显示。从 Claude 4.6 代开始,每个模型 ID 都是一个单一固定快照,因此这些模型只有一个条目。
