OpenAI's Chief Scientist Calls for a Coordinated Slowdown in Frontier Model Development

Jakub Pachocki, the chief scientist of OpenAI, published an essay titled "An Alien Mind" on 6 September, arguing that the industry should be prepared to decelerate. He wrote that competing to build the most capable systems regardless of the risk is indefensible once the scale of that risk is understood, and that labs should slow down together when their safety work cannot match the pace of their capability gains. Bloomberg reported that he urged "extreme caution" on the pace of development, and Decrypt summarized his position that no lab's current safeguards are adequate to keep building more powerful systems at full speed for much longer.

The concrete request is institutional rather than technical. Pachocki proposes that today's voluntary company commitments become mandatory safety thresholds, enforced by independent auditors, governments or international bodies. His stated worry is recursive self-improvement: models that run research projects and eventually improve themselves without a human involved in the process.

Two things are worth separating. OpenAI has announced no pause, no delayed launch and no change to its compute plans, so this is an argument made public by an executive, not a corporate decision. And a leading lab that proposes the rule usually finds it easier to meet than a smaller challenger does, which is the standard objection to safety-threshold proposals like this one. What is verified is that this kind of restriction is already happening in practice: OpenAI limited the strongest cyber capabilities of its Astra model to vetted testers, and Anthropic ships Mythos 5.1 only to organizations cleared through its Cyber Verification and Life Sciences Verification programs, currently inside the United States only.
