More than 1,100 AI workers and senior leaders from major frontier AI companies are urging the U.S. government to help develop an “AI slowdown” approach. According to a letter reported by multiple outlets, the statement—titled “Pacing the Frontier”—is signed by over a thousand people employed across companies including Anthropic, DeepMind, OpenAI, and Meta, with one report citing more than 1,200 signatories and another citing 1,134. The signers say their goal is not to halt AI progress, but to help pace the development and deployment of the most powerful systems.
The letter calls on Washington to support an international effort and to help build the tools needed to implement pacing—framing the request as support for practical measures that can influence how quickly frontier models advance. While the reports describe the signatories as executives and employees working on leading AI technologies, they do not specify the exact policy mechanisms the letter proposes. The core message highlighted across coverage is that workers in competing organizations are aligning on the need for government support in developing coordination and pacing capabilities for frontier AI development.
