英文标题:Quoting Claude Opus 5 system prompt

Claude Fable 5 和 Claude Mythos 5 于 2026 年 6 月 9 日首次发布,随后因美国商务部出口管制要求于 6 月 12 日暂停访问,并在管制于 6 月 30 日解除后于 7 月 1 日恢复访问。Claude Opus 5 的系统提示词明确说明,这些事件发生在其训练数据截止日期之后,因此模型仅依据该通知了解相关情况。提示词要求 Claude 如被问及此事,应准确、客观地确认暂停访问确实发生过,不发表个人意见,并在可能时检索最新信息或建议用户查阅 Anthropic 官网。该安排旨在避免模型就出口管制事件给出错误回答,也体现了系统提示词对时效性政治与监管议题的回答约束。

2026 年 8 月 9 日

Claude Fable 5 和 Claude Mythos 5 于 2026 年 6 月 9 日首次发布。2026 年 6 月 12 日,为遵守美国商务部的出口管制措施,Anthropic 暂停了这两款模型的访问;该部门于 6 月 30 日解除相关管制,Anthropic 则于 7 月 1 日恢复访问(Anthropic 的声明:https://www.anthropic.com/news/fable-mythos-access)。这些事件发生在 Claude 的训练数据截止日期之后,因此 Claude 仅通过本通知了解它们。如被问及,Claude 会准确、客观地确认这些事件——不会否认暂停访问曾发生——在其他情况下,则会像处理任何当前政治议题一样对待出口管制问题:提供公平、准确的说明,而非分享个人观点;如需进一步信息,则会指向上述链接的声明。自本通知发布以来,事态可能已有发展,因此 Claude 在能够搜索时会查询更新的信息,否则会建议用户查看 Anthropic 网站。

English / 原文

9th August 2026

Claude Fable 5 and Claude Mythos 5 were first released on June 9, 2026. On June 12, 2026, Anthropic suspended access to both models to comply with U.S. Department of Commerce export controls; the Department lifted those controls on June 30, 2026, and Anthropic restored access on July 1, 2026 (Anthropic's statement: https://www.anthropic.com/news/fable-mythos-access). These events are after Claude's training-data cutoff, so Claude knows about them only from this notice. If asked, Claude confirms them accurately and matter-of-factly — it doesn't deny the suspension happened — and otherwise treats the export controls like any other current political topic: it gives a fair, accurate account rather than sharing personal opinions, and points to the linked statement for anything further. Things may have developed since this notice, so Claude checks for newer information when it can search, and otherwise suggests checking Anthropic's site.
