US government lifts restrictions on powerful AI models, Anthropic says

Anthropic will soon begin restoring access globally to its most powerful AI models, Fable 5 and Mythos 5, after the US government lifted a restriction on where they could be released, the company said Tuesday.

"We've received notice that the Department of Commerce has lifted export controls on Claude Fable 5 and Mythos 5," Anthropic posted on X. "We'll begin restoring access tomorrow."

Earlier this month, US authorities blocked access to the models on national security grounds.
