US lifts export controls on Anthropic's Claude Fable 5 and Mythos 5, ending regulatory standoff

Anthropic announced that the U.S. Department of Commerce has lifted export controls on Claude Fable 5 and Mythos 5, ending a high-profile clash with the Trump administration that paused access for foreign nationals. The government had cited national-security authorities, and the move followed negotiations including permission for Mythos 5 to be released to a select group of partners and federal agencies. Anthropic will begin restoring access to Fable 5 as deployment resumes amid a broader AI-regulation push and the rise of cheaper Chinese open-source models.
