US lifts restrictions on Anthropic’s powerful AI models Fable and Mythos

The United States government has lifted its restrictions on foreign access to Anthropic’s most powerful AI models, the company has announced.

Anthropic said late on Tuesday that it would begin restoring access to Claude Fable 5 and Mythos 5 from tomorrow after the US Department of Commerce notified the company that it had removed its export controls.

“We’re grateful to our users for their patience, and to everyone who worked with us on redeploying the models,” Anthropic said in a statement posted on X.

Anthropic’s announcement came shortly after US Commerce Secretary Howard Lutnick said that his department had been coordinating with the company on the approval of its frontier models.

“Over the past two weeks, we have worked closely with Anthropic to analyze and approve Fable 5 to ensure alignment across the US Government and strengthen America’s leadership in AI,” Lutnick said in a post on X.

Anthropic abruptly shut off Claude Fable 5 and Mythos 5 last month after US President Donald Trump’s administration ordered the company to restrict all foreign nationals, including company employees, from accessing the models.

On Friday, the San Francisco-based company said that it had been granted approval to provide the models to US organisations that “operate and defend critical infrastructure”, and that it was working with the government to restore general access for the public.
