Artificial intelligence dominated the G7’s agenda in France after Washington abruptly barred foreign access to Anthropic’s most advanced models, Fable 5 and Mythos 5, citing national-security risks. The move, which applied even to the company’s non-U.S. employees, handed Europe a concrete example of the “kill switch” it has long feared and sharpened calls for tech sovereignty. French President Emmanuel Macron, keen to cement France’s AI credentials, is hosting leaders and industry chiefs—including Anthropic CEO Dario Amodei—for a working lunch expected to spotlight transatlantic tensions. Brussels, preparing to join Washington’s Pax Silica initiative on AI supply chains, bristled at being swept up in blanket export controls and warned allies shouldn’t be treated like adversaries. The Trump administration’s 2025 AI Action Plan prioritizes making American systems the global standard, but the sudden cutoff risks accelerating Europe’s drive to build homegrown alternatives, potentially reshaping market access and influence for U.S. AI firms.
