The U.S. Department of Commerce has withdrawn export control restrictions on Anthropic’s Claude Fable 5 and Mythos 5 AI models, ending a more than two-week suspension of the company’s most advanced systems.
Commerce Secretary Howard Lutnick announced the decision Tuesday, confirming that the Bureau of Industry and Security had reassessed the diversion risk associated with both models and determined that a license is no longer required for their export, re-export, or transfer, including to foreign nationals.
The restrictions were originally imposed on June 12, when the Commerce Department ordered Anthropic to suspend access to Fable 5 and Mythos 5 for all foreign nationals, including the company’s own non-U.S. employees, citing national security concerns.
According to Lutnick’s letter to Anthropic, the reversal follows two weeks of coordination between the company and federal officials, during which Anthropic agreed to proactively detect and report security risks, collaborate on release protocols for current and future models, and notify the government of any malicious activity involving Fable or Mythos.
Anthropic said it will begin restoring customer access to Fable 5 starting Wednesday across the Claude platform, Claude.ai, and Claude Code, with Mythos 5 access already extended in recent days to a limited group of government-approved organizations.
The Commerce Department noted that it reserves the right to reimpose restrictions if circumstances change or if Anthropic fails to meet its commitments going forward.
