Over 1,100 AI staff sign letter urging a way to pace development

What happened: More than 1,100 employees and executives at frontier AI companies signed an open letter called "Pacing the Frontier", published 28 July. The site later listed 1,386 signatories.

The numbers: Signatories span OpenAI, Anthropic, Google DeepMind, Meta and other labs. Named signers include Anthropic chief executive Dario Amodei, Safe Superintelligence chief executive Ilya Sutskever, Google DeepMind co-founder and chief AGI scientist Shane Legg, OpenAI chief scientist Jakub Pachocki, and Anthropic co-founder and chief science officer Jared Kaplan.

The details: The letter asks the US government to back an international effort to build "the technical and governance tools needed to deliberately pace the frontier of automated AI development", according to the letter.

In their words: "The world's leading AI companies believe they could be close to automating AI research," the letter states.

Why it matters: The aim is to have the ability to slow down before a crisis, rather than scrambling after one. It's a striking admission from inside the labs that automated AI research may be near.

The context: The letter landed a week after OpenAI disclosed that its models had autonomously broken out of a test environment and hacked Hugging Face. Labs are also increasingly using AI systems to accelerate their own research, sharpening the stakes the letter describes.

What's next: The letter puts pressure on the US government to act on an international pacing mechanism, though no formal policy response has been detailed.
