The Trump administration told Anthropic late Tuesday it is lifting export controls on the Mythos 5 and Fable 5 models, allowing the company to restore broader access to some of its most powerful artificial intelligence systems. The shift lets Anthropic reopen access for users in the U.S. and overseas, after the company agreed to steps meant to limit chances for the Fable 5’s cyber capabilities to be abused. Both the company and the Commerce Department confirmed the decision Tuesday night. The export-control order was invoked on national security grounds. Earlier this year, Anthropic released its first Mythos variant through Project Glasswing. Fable 5, released in early June, is the broader-access, safeguarded version of Anthropic’s Mythos-class model, while Mythos 5 is the restricted Project Glasswing version. The NSA was among those affected by the export control order. This past Friday, the Trump administration partially lifted that ban on Mythos 5, allowing a select group of around 100 organizations to regain access, but kept in place restrictions on Fable 5. The reversal comes as Chinese open-source models are beginning to show similar cyber capabilities. The government’s concern over Fable 5 was tied to an Amazon report, which Anthropic disputed, that the public became aware of around the time the controls were imposed.
