Canadian Prime Minister Mark Carney warned on Sunday that U.S. restrictions on Anthropic's advanced AI models highlight the dangers of relying on a few American providers. The U.S. government ordered Anthropic to disable its Fable 5 and Mythos 5 models for all users worldwide on national security grounds, citing concerns over a China-linked group accessing Mythos. Carney, speaking ahead of the G7 summit, emphasized the need to diversify AI sources to avoid single points of failure. Anthropic complied but disputed the basis, noting similar vulnerabilities exist in public models like OpenAI's GPT-5.5. The event has spurred interest in decentralized AI projects, whose market cap rose 12% in a week, with tokens like ChainOpera AI and io.net surging over 30%. However, observers caution that decentralization may only shift the risk to chip suppliers if compute remains concentrated among a few firms. Carney's warning echoes systemic risk concerns similar to the 2008 financial crisis.
