US Commerce Dept Orders Anthropic to Cut Off Fable 5, Mythos 5 for Foreign Nationals

The US Commerce Department on June 12, 2026 issued an export control directive requiring Anthropic to cut off access to its Fable 5 and Mythos 5 models for all foreign nationals inside and outside the US, prompting Anthropic to immediately disable both models for all customers to comply. In an official statement, the company said the directive was issued over national security concerns, noting that "the net effect of this order is that we must abruptly disable Fable 5 and Mythos 5 for all our customers to ensure compliance." The measure extends even to the company's foreign employees, while its other Claude models are unaffected.
