美国禁令导致两款模型下线
美国以国家安全为由发布出口管制指令，要求暂停所有外国国民（包括外国籍 Anthropic 员工）对 Fable 5 和 Mythos 5 的访问。Anthropic 已从模型选择器中移除 Fable 5，现有会话自动回退至 Opus 4.8（按 Opus 4.8 定价）。其他 Claude 模型不受影响。Anthropic 认为这是误解，正在争取恢复访问。

Claude Fable 5 has been suspended following a US government directive. Details here: x.com/AnthropicAI/st… . We've removed Fable 5 from our model picker for now. Any new and existing agent sessions in Cosmos that were pre-configured to use Fable 5 will now fallback to Opus 4.8 (at Opus 4.8 pricing). No action is needed unless you choose to switch to another model. All other models remain fully accessible. Anthropic @AnthropicAI 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.
