The United States has lifted export restrictions on Anthropic's most advanced AI models, the company said late on Tuesday, after Washington suspended access over national security concerns about three weeks ago. The move marks a significant shift in the US regime's approach to controlling frontier AI technology.
"We've received notice that the Department of Commerce has lifted export controls on Claude Fable 5 and Mythos 5," Anthropic posted on X. "Claude Fable 5 will be available again globally tomorrow," the company added. The US government had ordered Anthropic on June 12 to suspend access to the advanced models for foreign nationals, including Anthropic employees, after identifying potential vulnerabilities.
Last week, authorities allowed a small group of American cybersecurity firms access to Mythos 5. In a letter seen by Reuters, Commerce Secretary Howard Lutnick said the restrictions were lifted after Anthropic agreed to certain commitments. Lutnick added the department could reimpose restrictions if circumstances change or the company fails to meet its commitments.
Earlier this month, US President Donald Trump signed an executive order establishing a voluntary framework for AI developers to offer "covered frontier models" to the US government for up to 30 days before releasing them to trusted partners. The Trump administration's tough approach cites concerns that advanced AI models could be misused by military or intelligence agencies in China, Russia and other countries.
On Tuesday, CIA Director John Ratcliffe compared the capabilities of the most advanced artificial intelligence models to nuclear weapons. Some European lawmakers, meanwhile, described Washington's ability to shut off access as a "kill switch" that reinforced the need for the European Union to secure its own AI sovereignty.
Artificial Intelligence giant OpenAI has also limited the rollout of its latest GPT-5.6 model to vetted partners at the US government's request, while delaying a full public launch. "This isn't quite the process that we think is optimal," OpenAI CEO Sam Altman posted on X on Friday.
