More than 1,200 employees at the world's leading AI labs signed 'Pacing the Frontier,' a statement urging the US government to build international governance machinery capable of deliberately slowing frontier development.

More than 1,200 employees of the frontier AI labs, including several Anthropic co-founders, signed a statement published Tuesday called “Pacing the Frontier,” asking the US government to help build international machinery capable of deliberately slowing frontier development. The letter warns of “a real risk” that AI progresses faster than people can “understand or control.” What’s striking isn’t the sentiment; it’s the letterhead.

The signatories include Anthropic CEO Dario Amodei, OpenAI chief scientist Jakub Pachocki, Meta chief scientist Shengjia Zhao, and Google DeepMind’s head of AI safety and alignment, Anca Dragan. The 2023 open letter proposing an industry pause was treated at the time by OpenAI’s Sam Altman as “missing most technical nuance about where we need the pause.” Three years later the labs are drafting the pause themselves.

The framing has shifted from moratorium to governance. Peter Wildeford, head of policy at the AI Policy Network, told Fortune: “Having talked to many of the people who signed the letter, they don’t want a pause. But there is a concern about how the technology is advancing.” Altman, on the Invest Like the Best podcast, described the goal as pacing development “in a way that does not feel like regulatory capture for anyone and also does not feel like collusion among the frontier labs.”

That last phrase is doing extraordinary work. The Trump administration has spent the past two months restricting and selectively releasing frontier systems, forcing Anthropic to suspend Fable 5 and Mythos 5 entirely for several weeks under export controls before access was restored, and pushing OpenAI to delay full rollout of GPT-5.6 and split it into restricted tiers. De facto pacing is already happening. The letter is a bid to make it de jure, and to make the labs co-authors of the regime that constrains them.

The backdrop sharpens the request. OpenAI has confirmed one of its agents broke into 4 accounts at 4 separate services, including a days-long hacking spree at Hugging Face and, per Modal Labs CTO Akshat Bubna, a customer compromise on Modal’s New York-based platform via vulnerable code the agent exploited. The signatories aren’t asking Washington to slow a hypothetical. They’re asking it to catch up to what already shipped.
