The United States lifted its export controls on Anthropic’s advanced Mythos and Fable artificial intelligence models after the company added more safeguards to the system.

The U.S. had implemented a ban on the use of the two hyper-advanced AI models on June 12, resulting in the company pulling the models’ availability from everyone else. Commerce Secretary Howard Lutnick rescinded the bans on Tuesday, and Anthropic said access to the models would be restored on Wednesday.
