OpenAI, Anthropic and Microsoft sign Macron's Paris Call, pledging fail-safe shutdowns for frontier AI

French President Emmanuel Macron convened governments and AI developers on Nov. 9 to sign the Paris Call for AI Safety and Security, a voluntary declaration released on the eve of the Paris Peace Forum. Signatories include Bahrain, Canada, Finland, France, Norway and the Netherlands, later joined by Cyprus and Kenya, along with Anthropic, OpenAI, Microsoft, Mistral AI, Hugging Face, Cohere, Black Forest Labs, Sakana AI, Synthesia and Domyn. Frontier developers commit to disclose model capabilities and known risks, support proportionate independent evaluations, and implement fail-safe mechanisms to restrict, pause or shut down model operations within their control, including during training and internal use. The text also calls for common evaluation standards and shared incident reporting and early-warning systems. It sets no enforcement mechanism, deadlines or sanctions, and the US and Chinese governments, Google and Meta did not sign.
