The Trump administration has lifted its restrictions on Anthropic’s most advanced AI models, the company announced late on Tuesday, noting that it will start restoring access to its users and business customers globally starting Wednesday.

In a post on X , Anthropic said it was informed that the Department of Commerce lifted export controls on Claude Fable 5 and Mythos 5.

The move comes two and a half weeks after the government abruptly banned the company from allowing foreign nationals—including Anthropic employees who are not U.S. citizens—from accessing its newest models, citing national security concerns.

Secretary of Commerce Howard Lutnick tweeted that the government had “worked closely” with Anthropic over the past two weeks to “analyze and approve Fable 5” and “strengthen America’s leadership in AI.”

A letter from Lutnick to Anthropic, cited by multiple outlets , noted that the company had coordinated with the government to “proactively detect and address security risks” associated with the two models.

The company has also worked to inform the government if it detects any malicious activities involving the models.

Lutnick’s letter warns that the Trump administration reserves the right to reimpose restrictions in the future if “circumstances change or should Anthropic fail to adhere to its commitments.”

In a post on X, White House Chief of Staff Susie Wiles wrote : “My gratitude to companies across industries who continue to work closely with the White House to implement the President’s EO: ‘Promoting Advanced AI Innovation and Security.’ This includes excellent work around advanced model access and guardrail testing and security…Our shared priority remains: get the best tech deployed as quickly and safely as possible.”
