An open letter signed by 1,224 employees of frontier AI companies, including key figures from OpenAI and Anthropic, requests that the U.S. government support an international effort to develop technical and governance tools capable of deliberately pacing the frontier of automated AI development.
The signatories argue that while AI could create a better future, there is a real risk that capability development will accelerate beyond human ability to understand or control resulting systems. The letter distinguishes its request from immediate pauses, focusing instead on preparing mechanisms for future coordination to buy time for security measures and oversight.
Both OpenAI and Anthropic have officially endorsed the letter, with Anthropic citing recent research on recursive self-improvement as evidence of the need for such tools. The initiative aims to establish groundwork for cooperation between companies and governments before automated AI research potentially accelerates uncontrollably.
