Canadian Prime Minister Mark Carney said Sunday U.S. restrictions on Anthropic’s newest AI models show the dangers of overreliance on a limited number of American providers.

The company said it received the export control directive on Friday from the government.

The US government restrictions cite national security concerns over the AI models Fable 5 and Mythos 5.

Tech experts advocate for Sovereign AI amid US blocking access to Anthropic's models, warning of business risks from service suspensions.
