U.S. Commerce Department lifts export ban on Anthropic's Mythos and Fa

The U.S. Commerce Department has officially lifted export controls on Anthropic's advanced Fable and Mythos AI models, less than three weeks after the company was ordered to suspend foreign national access over security fears.

In a letter to Anthropic seen by Reuters, Commerce Secretary Howard Lutnick confirmed that a license is no longer required for the export, re-export, or in-country transfer of the Mythos or Fable models.

As part of the resolution, Anthropic has agreed to proactively detect and address security risks, work with the government on standards for future models, and immediately report any malicious activity to U.S. authorities.

The government's selective vetting process had drawn criticism from OpenAI CEO Sam Altman, who remarked: 'I just don't like the idea of the government picking the customers.' OpenAI itself has delayed its GPT-5.6 rollout at federal request.
