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. He said the task of AI safety should not be left to tech companies.

Overshadowing the discussion on AI was Donald Trump’s administration’s directive last week, preventing foreign nationals from using Anthropic’s newest and most powerful artificial intelligence models.
