More than 1,100 employees from the world's leading artificial intelligence companies signed a statement on July 28, 2026 urging the United States government to support an international effort to deliberately slow, or "pace," the development of advanced AI systems.
The initiative, called "Pacing the Frontier," was first reported by Bloomberg and Reuters. It draws signatories from Meta Platforms, Anthropic, OpenAI, and Alphabet's Google, with backing from the nonprofits Guidelight AI Standards and Encode AI.

A Direct Appeal to Government
The statement is unusually pointed for a letter signed by current employees of the very companies building the technology. "We request that the U.S. government support an international effort to develop the technical and governance tools needed to deliberately pace the frontier of automated AI development," the signatories wrote.
The letter comes as AI companies pursue increasingly powerful systems, raising concerns that development could outpace existing safety, governance, and oversight mechanisms. Unlike earlier public warnings that came mostly from external researchers or former employees, this appeal was endorsed by people still working inside the labs racing to build frontier models.
Who Signed
The signatories include several high-profile figures directly responsible for some of the field's most advanced work. According to Reuters, they include Meta's vice president of AI research Dawn Song, Anthropic co-founders Jared Kaplan and Chris Olah, and OpenAI Chief Scientist Jakub Pachocki. The breadth of the names gives the statement weight that ordinary advocacy letters lack, since the signatories are among those best positioned to judge how quickly capabilities are improving.
The involvement of employees from competing firms, including the two companies most associated with the frontier model race, suggests a degree of cross-industry consensus that the pace of progress has become a genuine policy concern rather than a niche worry.
How the Companies Responded
OpenAI publicly addressed the statement on the social platform X. "We believe that, at some point in the future, AI acceleration for frontier model development may be so high that the world will need to pace the rate of AI advancement," the company posted. The remark was a notably measured acknowledgment from a firm that has otherwise emphasized speed and scale, though it stopped short of endorsing any specific mechanism for slowing development.
The letter also builds on earlier moves by individual labs. Last month, Anthropic called on major AI companies to consider a coordinated pause in development, warning that advances could soon allow AI systems to improve themselves faster than society can manage the resulting risks. The "Pacing the Frontier" statement effectively extends that call from a single company to a coalition of employees across the industry.
A Competitive Landscape Complicates the Ask
The central tension behind the letter is one that has defined AI policy debates for years: while individual companies and researchers may favor slowing down, no firm wants to unilaterally cede ground to rivals. A pause by one lab could simply hand an advantage to competitors, particularly those outside the United States. That is why the signatories are pressing for a government-backed, international framework rather than voluntary corporate restraint.
The appeal also arrives amid a separate push to strengthen AI safety tooling. On Monday, Nvidia announced that it had formed a coalition with Adobe, CrowdStrike, and other companies to develop AI safety and cybersecurity tools. That effort followed a recent cybersecurity incident on the Hugging Face platform involving autonomous AI agents, which heightened concerns about the risks of systems that can act independently online.
What 'Pacing' Could Mean
The letter does not prescribe a single policy, but the phrase "technical and governance tools" points toward a range of possible measures: shared safety standards, pre-deployment testing requirements, compute monitoring, or coordinated development timelines among major labs. Such tools would require unprecedented coordination between governments and the private sector, and would need to include international partners to prevent development from simply moving to less regulated jurisdictions.
Critics of slowdown proposals have long argued that over-regulation could stifle innovation and cede leadership in a strategically vital technology. Supporters of the letter counter that the risks of moving too fast, from security failures to systems that act unpredictably, now outweigh the costs of added caution. What is clear from the signatory list is that this argument is no longer being made only by outside critics; it is being made by the people building the systems themselves.
Industry-Led Safety Efforts
The letter is part of a wider, industry-driven push to build practical guardrails even as development accelerates. The involvement of nonprofits Guidelight AI Standards and Encode AI, the latter a youth-led organization focused on AI policy, signals an effort to bring civil-society voices into a debate that has often been dominated by corporate and government interests. Encode AI has previously advocated for stronger oversight of frontier models, and its backing gives the statement a grassroots dimension that purely corporate appeals have lacked.
The timing also matters. Governments around the world are still negotiating how to regulate advanced AI, and there is no consensus mechanism for coordinating development timelines across borders. By asking specifically for a government-backed, international approach, the signatories are effectively telling policymakers that voluntary corporate restraint is not enough and that only a coordinated framework can prevent a race-to-the-bottom dynamic among competing labs.
