The United States has removed restrictions on foreign access to Anthropic’s most powerful artificial intelligence models, the company said. The decision clears the way for Anthropic to restore access to Claude Fable 5 and Mythos 5 after export controls had limited their availability outside the US.
Anthropic said late Tuesday that the US Department of Commerce had notified the company that the controls had been lifted. The company said it would begin restoring access to the two models from Thursday.
In a statement posted on X, Anthropic thanked users for their patience and thanked those who worked with the company on redeploying the models. The company did not give further details in the announcement on where access would resume or how many users had been affected.
Commerce Department says it reviewed Fable 5
The announcement followed comments from US Commerce Secretary Howard Lutnick, who said on X that his department had been working with Anthropic on approval of the company’s frontier models. Lutnick said the department had worked closely with Anthropic over the previous two weeks to analyze and approve Fable 5.
Lutnick said the review was intended to ensure alignment across the US government and support US leadership in AI. He did not provide a separate timeline for Mythos 5 in the post cited by Anthropic’s announcement.
The Commerce Department’s move affects Claude Fable 5 and Mythos 5, which Anthropic described as its most powerful AI models. Anthropic’s statement framed the change as a return of access rather than the launch of new products.
The company’s update did not say when the restrictions were first imposed or identify which foreign markets had been blocked. It also did not describe any conditions attached to the Commerce Department’s removal of the export controls.
Anthropic is one of the US companies developing advanced AI systems, and its Claude models compete in a fast-moving field of frontier AI tools. The Commerce Department’s involvement shows that access to top-tier AI models remains subject to US government review when export controls are applied.
Anthropic said access restoration would begin from Thursday, following the Commerce Department notification. Further details on the rollout were not included in the company’s statement.
