The U.S. government issued an export control directive under national security authority requiring a halt to all foreign nationals’ access to Fable 5 and Mythos 5, including Anthropic employees who are foreign nationals. According to Odaily, to comply, Anthropic must shut off all customers’ access to Fable 5 and Mythos 5, while all other Anthropic models are unaffected.
The U.S. government’s oral evidence cited a potential narrow, non-general jailbreak method in the models. Anthropic said it has complied with the legal directive and removed access for all users, but it disagreed with the decision to withdraw deployed commercial models based on the discovery of a narrow potential jailbreak and said it is working to restore access as soon as possible.
