1,000+ frontier AI staffers call for slower development

More than 1,000 employees from leading AI labs, including OpenAI, Anthropic, Meta, and Google, signed a public letter urging U.S. policymakers to support tools and policies that could slow the pace of AI development if needed. The statement does not ask for a full pause. Instead, it argues for an international approach that would let governments and labs deliberately slow progress as AI systems move closer to autonomous research. Supporters of the letter say the risk is that AI systems could improve themselves faster than people can understand or control them. OpenAI and Anthropic also publicly backed the effort, adding to a growing debate over how quickly frontier AI should advance.
