The U.S. Commerce Department lifted export controls on Anthropic’s Fable 5 and Mythos 5 artificial intelligence models. The decision ends a ban imposed in June over national security concerns.

The government cleared the models after Anthropic implemented enhanced safety protocols. These measures mitigate risks that the AI could be used for cyberattacks.

The move benefits Amazon, a primary investor and partner to Anthropic. Anthropic utilizes Amazon Web Services (AWS) to train and run its models. The company has committed to spending billions on the platform. The lifted restrictions allow Anthropic to resume full operations. This secures a lucrative revenue stream for Amazon’s cloud division.
