  • The U.S. government ordered Anthropic to suspend access for all foreign nationals to its Fable 5 and Mythos 5 AI models, citing national security concerns.
  • The suspension impacted foreign nationals, including those who work for Anthropic, and the duration of this limitation remains unclear.
  • This order represents a new challenge in Anthropic’s relationship with the federal government and is a rare example of regulatory intervention in a technology firm’s operations.
  • It’s the second time the Trump administration has targeted Anthropic; previously, the Pentagon declared Anthropic an unacceptable supply chain risk.
  • Foreign restrictions could theoretically even block employees from allied nations like Canada and Britain from working on the AI models.
  • Anthropic believes the government’s decision was an overreaction and is working to restore access.
  • Mythos and Fable 5 were unveiled with limitations to prevent misuse by hackers, which the government seems to have endorsed.
  • The order contrasts with other recent Trump administration policies that allowed some advanced AI chips to be sold to China, raising eyebrows among experts.
