Anthropic said on Friday night that the U.S. government had ordered the company to suspend access for all foreign nationals to its Fable 5 and Mythos 5 artificial intelligence models, citing national security concerns.
The company revealed the order in a social media post, saying that it “must abruptly disable Fable 5 and Mythos 5 for all our customers to ensure compliance.” Foreign nationals who work for Anthropic are also affected by the suspension.
Anthropic unveiled Claude Mythos in April, but said it could not share the A.I. system with the public because it could become a powerful tool for hackers looking for ways to break into computer networks.
The new A.I. system quickly became a security concern in Washington and Silicon Valley because it could represent what experts had worried about for several years:that A.I. represented a new and far more dangerous threat to computer networks.

Anthropic shared the Claude A.I. system with about 40 organizations that maintain critical computer infrastructure so they could use the system to patch security vulnerabilities before hackers exploited them.
The order to limit access to the new A.I. models came from the Commerce Department, said a person familiar with it who spoke on the condition of anonymity. It was unclear how long the restrictions will last.
