美国政府出于国家安全考量，下令要求 Anthropic 暂停让任何外国籍人士存取其 Fable 5 和 Mythos 5 人工智慧模型，主因是发现该模型存在被绕过安全限制（越狱）的风险。

为了确保合规，Anthropic 已对所有客户全面关闭这两个模型的存取权限，但该公司对此行政命令表示反对，认为这项针对单一漏洞的封锁措施可能会开创恶劣先例，甚至导致整个前沿 AI 行业的部署停摆。

此举不仅加剧了 Anthropic 与川普政府之间的紧张关系，也引发了整个 AI 行业对政策走向的担忧，同行如 Cohere 的创办人指出，这对国际技术联盟以及其他大型 AI 开发商而言是一个重大的警钟。

Citing national security concerns, the US government has ordered Anthropic to suspend access to its Fable 5 and Mythos 5 AI models by foreign nationals, following the discovery of a jailbreak vulnerability that bypasses model guardrails.

To ensure compliance, Anthropic shut off access to both systems for all customers, though the company expressed disagreement with the sweeping order, warning that such a standard could halt new model deployments across the entire frontier AI industry.

This unprecedented move escalates tensions between Anthropic and the Trump administration while raising industry-wide concerns about setting a precedent for other AI developers and impacting long-standing global technological alliances.
