Anthropic@AnthropicAI · XAnthropic宣布，美国政府根据国家安全指令，暂停所有外国国民（包括Anthropic外籍员工）对Fable 5和Mythos 5的访问权限。Anthropic必须立即为所有客户禁用这两个模型以确保合规，其他Claude模型不受影响。公司表示这可能是误解，正在尽快恢复访问。
The US government， citing national security authorities， has issued an export control directive to suspend all access to Fable 5 and Mythos 5 by any foreign national， whether inside or outside the United States， including foreign national Anthropic employees.
The net effect of this order is that we must abruptly disable Fable 5 and Mythos 5 for all our customers to ensure compliance.
Access to all other Claude models is not affected.
We apologize for this disruption to our customers. We believe this is a misunderstanding and are working to restore access as soon as possible.
