Anthropic has disabled its two most capable AI models, Fable 5 and Mythos 5, after the U.S. government issued an export control directive late on June 12 ordering the company to block access for any foreign national, whether inside or outside the United States, including Anthropic's own foreign-national employees.
Because the company says it cannot reliably separate foreign users from the rest of its base in real time, the practical result is a worldwide shutoff of both models. All other Anthropic models remain online. The US government, citing national security authorities, delivered the directive to Anthropic at 5:21 PM ET on Friday, June 12, 2026.
