Anthropic cuts off Fable 5 and Mythos 5 access following government order

受政府指令影响，Anthropic 切断了 Fable 5 和 Mythos 5 的访问权限

An export control directive citing national security concerns required blocking access for all foreign nationals. 一份援引国家安全担忧的出口管制指令要求禁止所有外国公民访问这些模型。

On Friday evening, the government ordered Anthropic to block access to Fable 5 and Mythos 5 for all foreign nations, both inside and outside the US, due to national security concerns. That order included employees of Anthropic. To meet those demands, the company has completely cut off access to the models for all customers. 周五晚上，政府以国家安全为由，下令 Anthropic 禁止所有外国公民（无论身处美国境内还是境外）访问 Fable 5 和 Mythos 5。该指令同样适用于 Anthropic 的员工。为了满足这些要求，该公司已完全切断了所有客户对这些模型的访问权限。

In a statement, Anthropic said that while it was complying with the order, the government “did not provide specific details of its national security concern.” Instead, it claims that any evidence of potential jailbreak was provided verbally, and that the vulnerabilities discovered were minor and available via other models, including GPT 5.5. Anthropic 在一份声明中表示，尽管公司正在遵守该指令，但政府“并未提供有关其国家安全担忧的具体细节”。相反，该公司声称，任何关于潜在“越狱”（jailbreak）的证据都是口头提供的，且所发现的漏洞非常轻微，在包括 GPT 5.5 在内的其他模型中同样存在。

In its statement, the company lays out the steps it took to safeguard Fable and Mythos, including working with the US and UK governments and changing its data retention policy to help track attempts to use them for malicious purposes. It goes on to say that: 在声明中，该公司列举了为保护 Fable 和 Mythos 所采取的措施，包括与美英政府合作，以及更改数据保留政策以协助追踪恶意使用行为。声明进一步指出：

We have not even received a disclosure of a concerning non-universal potential jailbreak that led to a harmful result. The potential jailbreaks that have been disclosed to us are either entirely benign responses or are minor findings that provide no Mythos-specific uplift. “我们甚至没有收到任何关于导致有害结果的、令人担忧的非通用型潜在越狱披露。目前向我们披露的潜在越狱要么是完全无害的响应，要么是不会为 Mythos 带来任何额外风险的轻微发现。”
