French President Emmanuel Macron on Wednesday urged the world's wealthy democracies to work together on regulating advanced artificial intelligence systems, speaking at a high-level meeting that included top AI executives. OpenAI CEO Sam Altman issued a similar plea at the Group of Seven summit of major industrialized nations in France, saying an "international forum" is needed for countries to draw up AI guardrails, and that the task of AI safety should not be left to tech companies. Overshadowing the discussion was President Donald Trump's administration's directive last week, preventing foreign nationals from using Anthropic’s newest and most powerful artificial intelligence models. Macron said it was a “good thing” that U.S. officials recognize that so-called frontier AI models could be dangerous, but criticized it as a “strictly nationalist” reaction. The company was forced on June 12 to take its latest AI models, known as Fable 5 and Mythos 5, offline to comply with the directive. Macron made a forceful plea for the U.S. not to keep cutting-edge AI to itself, warning of a possible drop in value for U.S. firms if they switch off access. He said France will boost funding for its own AI industry as an insurance policy. Altman said the technology's future must be shaped by people, democratic institutions and society as a whole, "not just by the companies building the most capable systems,” and called for "an international forum for discussion that establishes globally accepted standards for testing."
