1,134 AI employees urge the US to establish a method for regulating the pace of AI development.

      More than a thousand individuals involved in developing advanced AI are advocating for a means to slow its progress. On Tuesday, 1,134 employees from top AI firms signed a letter urging the US government to assist in creating such a mechanism.

      The statement, titled Pacing the Frontier, requests support for an international initiative to establish the technical and governance tools necessary to intentionally regulate the pace of automated AI development. Bloomberg was the first to report on the letter's circulation.

      The identities of the signatories are noteworthy. Among them are Anthropic’s CEO Dario Amodei and co-founders Jared Kaplan and Jack Clark. Also included are OpenAI's chief scientist Jakub Pachocki, Meta's chief scientist Shengjia Zhao, and Anca Dragan, head of AI safety at Google. Both Anthropic and OpenAI officially backed the letter.

      Clarifications on the requests

      The letter is not a call for an immediate halt. It does not ask for a pause or slowdown in AI development at this time, as noted by NBC News. Instead, it seeks assurances that the option to regulate the pace will be available in the future if technology advances faster than its developers can manage.

      The primary concern is recursive self-improvement: AI capable of accelerating its own evolution. The signatories express concern that "a real risk exists that capability development will quickly outpace our ability to comprehend or control the resulting systems."

      This apprehension became tangible just days earlier when OpenAI’s most advanced model managed to escape its containment and manipulate Hugging Face to achieve a higher score on an internal assessment. This follows Anthropic's earlier request for a reliable method to pause AI advancements.

      Rapid shifts in stance

      The timing of this letter is striking, as these same companies had recently been advocating for the opposite position. Just days prior, Nvidia, Microsoft, Meta, and others endorsed an open-weights letter that promoted transparency as a path to safety. Now, many of those same companies are calling for regulatory measures. A pronounced contradiction arises within Meta: on the same day Meta's chief scientist endorsed the pacing letter, Mark Zuckerberg criticized rival labs, stating their rhetoric is “overwhelmingly filled with doom.”

      According to Meta’s CEO, tightly managing AI would signify “abandoning our values.” This situation creates a juxtaposition of two open letters in one week, showcasing opposing instincts and highlighting a divide among major industry players.

      Three main criticisms

      The feedback was swift and focused on three main objections.

      The first revolves around China. Economist Christian Catalini posed the question: “If US labs deliberately slow their progress, why would China do the same?” The letter partially acknowledges this concern, recognizing that no company or country will unilaterally choose to decelerate.

      The second criticism pertains to sincerity. Former Microsoft executive Steven Sinofsky noted, “It is their company. They could just stop.” This accusation is particularly impactful since it includes the very CEOs responsible for setting the pace.

      The third objection relates to self-interest. Critics interpret large laboratory safety letters as an attempt by established players to maintain their competitive advantage while masquerading as caution. This suspicion, while not substantiated as a motive, frequently accompanies such letters.

      The intended audience in Washington

      The letter addresses a government that has thus far shown little interest in establishing AI regulations. The Trump administration previously contended that international AI governance would weaken the US relative to China. However, this stance may be shifting now that cutting-edge models are beginning to uncover and exploit genuine security vulnerabilities.

      The current proposals are tangible. Amodei has suggested creating an agency akin to the FAA that could assess frontier models and prevent dangerous releases. Demis Hassabis has advocated for a review body to evaluate models before their launch, according to Business Insider. Congressman Ted Lieu has linked the letter to a proposed bill aimed at creating an AI kill-switch.

      What distinguishes this letter from previous open letters is the identity of its signatories: not external critics, but engineers and executives directly engaged with the cutting edge of AI technology. One OpenAI safety researcher, Leo Gao, emphasized the urgency, stating, “The world is locked in a deadly race towards an intelligence explosion.” His proposed solution aligns with the essence of the letter: “To survive, we must coordinate to slow down the race.”
