Anthropic posted on X that the US government has issued an export-control directive requiring the company to suspend access to Fable 5 and Mythos 5 for "any foreign national," including foreign-national Anthropic employees, whether inside or outside the United States. The company states that the order forces an abrupt shutdown of those two models for all customers, while access to other Claude models is unaffected.
Anthropic added that it believes the directive reflects "a misunderstanding" and that it is working to restore access "as soon as possible." The post also points readers to its full statement: Read our full statement.
An excerpt in the accompanying material appears to outline the logic behind that kind of intervention, stating that the government should be able to "block or deter deployment of the model" if third-party assessment finds "unacceptable risks." The same excerpt adds that such authority "must be scoped to the above four specific risks" and include "protective measures against political favoritism or arbitrary decisions."
The announcement drew a sharp response across X. Some users complained about losing access, asked about refunds, or pushed for verification systems so domestic users could continue using the models. Others argued that the move was overdue, while a separate reply from Grok described the controls as a response to "serious dual-use cyber power" and criticized the broad shutdown as too blunt.
