The Trump Administration Is Removing Export Restrictions on Anthropic’s Mythos and Fable AI Technologies.

The Trump administration is removing export controls on Anthropic’s two most advanced AI models following a deal with the Commerce Department. This update was conveyed in a letter from Commerce Secretary Howard Lutnick to Anthropic cofounder Tom Brown, which was reviewed by WIRED.

The department is lifting restrictions on both the Fable 5 model and the more advanced Mythos 5 model, which had previously been allowed for release only to certain companies and government entities. “A license is no longer required for the export, reexport, or in-country transfer, including deemed export or deemed reexport, of the Mythos or Fable models,” Lutnick stated.

These developments occur as Anthropic collaborates with the Commerce Department and the White House to enhance safeguards preventing users from circumventing Fable’s safety measures to access restricted functionalities, particularly those linked to cybersecurity, as per sources familiar with the situation.

“Among other commitments, Anthropic has agreed to proactively identify and mitigate security risks associated with the models; to work closely with the U.S. government on protocols, standards, and releases for Mythos, Fable, and future models,” wrote Lutnick.

Lutnick has been at the forefront of the Trump administration’s initiatives to resolve its disagreements with Anthropic, alongside national cyber director Sean Cairncross.

Originally, Anthropic argued that the administration’s security concerns were exaggerated. The company claimed it was impossible to guarantee that there would be zero jailbreaks that could unlock the enhanced features of the restricted Mythos model.

Recently, Anthropic shifted its strategy to reinstate Fable, which has also involved altering the company’s communication approach with the administration. WIRED previously reported that Anthropic CEO Dario Amodei was replaced in meetings with Brown, who was favored by officials on a personal basis.

Anthropic also assured the administration of its intention to decrease the frequency of jailbreaks by implementing stronger safeguards, effectively communicating what the administration wanted to hear rather than reopening discussions on the fundamental issue of whether jailbreaks can be prevented, sources said.
