The Commerce Department lifted restrictions on all of Anthropic’s artificial intelligence models on Tuesday, June 30, 2026, allowing the company to bring its most powerful AI technologies back online, according to a letter from the government to the company that was viewed by The New York Times. Commerce Secretary Howard Lutnick told Anthropic that it would no longer need a license for exports or in-country transfers of its Claude Mythos and Claude Fable AI models, reversing an order issued June 12. “Anthropic has taken steps in close coordination with the U.S. government to address the risks associated with Claude Mythos 5 and Claude Fable 5,” Lutnick wrote. Citing national security, the Commerce Department had initially ordered Anthropic to suspend access to its latest AI models for all foreign nationals. The restrictions were the second time the Trump administration had targeted Anthropic, which is based in San Francisco. In March, the Pentagon labeled Anthropic an unacceptable supply chain risk, and Anthropic has sued the federal government over that designation. Lutnick said Anthropic had agreed to steps including proactively detecting and addressing security risks, working with the U.S. government on protocols and standards, and informing the government of any malicious activity.
