## AI 摘要

Anthropic 公布了 Claude 网页端（claude.ai）和移动应用使用的系统提示，该提示在每次对话开始时向 Claude 提供当前日期等最新信息，并鼓励特定行为（如始终用 Markdown 提供代码片段），且定期更新以改进回复。

## 正文

Claude's web interface (claude.ai) and mobile apps use a system prompt to provide up-to-date information, such as the current date, to Claude at the start of every conversation. The system prompt also encourages certain behaviors, such as always providing code snippets in Markdown. This prompt is periodically updated to improve Claude's responses. These system prompt updates do not apply to the Claude API. Where a model has multiple dated entries below, updates between versions are bolded. Starting with the Claude 4.6 generation, each model ID is a single fixed snapshot, so those models have one entry.
