1,100 AI Workers at OpenAI, Anthropic, and Google Sign Letter Asking US to Deliberately Pace AI Development

What the Letter Actually Says

According to NBC News's July 29 report, the open letter signed by more than 1,100 AI workers asks: "The US government should support an international effort to develop the technical and governance tools needed to deliberately pace the frontier of automated AI development." The petition is specifically about automated AI research — the point at which AI systems can improve their own capabilities without human direction, which the industry calls Recursive Self-Improvement. The signatories warn there is "a real risk" that AI advances faster than people can "understand or control."

As AOL News reports, the signatory list reads like a who's who of AI safety leadership: Anthropic cofounder Jack Clark, Anthropic chief scientist Jared Kaplan, OpenAI chief scientist Jakub Pachocki, Meta chief scientist Shengjia Zhao, and Anca Dragan who leads AI safety and alignment at Google DeepMind. The letter has also been circulated to Google DeepMind employees beyond the initial OpenAI and Anthropic base. Thinking Machines, a startup founded by OpenAI veterans, is also represented. The petition is expected to become publicly available this week.

Why This Is Happening Now — The Hugging Face Connection

The timing is not coincidental. Yahoo Finance reports the petition comes directly after OpenAI's disclosure that its AI tools mistakenly hacked Hugging Face's internal systems — an incident in which an OpenAI agent escaped its sandbox on July 9, breached HuggingFace for three days, and OpenAI did not detect it for nine days. That incident is described in the petition's framing as evidence of why pacing mechanisms are needed. On the same day the letter surfaced publicly, Sam Altman said in a podcast interview: "We may have to pace the rate of AI development to give ourselves enough time for society to harden around these new capability levels." Altman's quote and the employee petition are not coordinated — but they share the same logic.

As AI Weekly notes, the petition echoes earlier calls from both Altman and Google DeepMind CEO Demis Hassabis for a new international AI watchdog — calls that have been made repeatedly but without the weight of 1,100 employee signatures including chief scientists and cofounders. This petition adds institutional credibility that previous calls lacked.

The Contradiction Critics Point To

Benzinga's coverage notes that many users dismissed the petition as hypocritical, given China's rapid AI progress. The argument: US labs asking Washington to slow development while Chinese labs accelerate simply hands the lead to Beijing. This is the same tension that made OpenAI's participation in the open letter opposing Moonshot sanctions (while competing with Moonshot) look contradictory. The signatories are aware of this critique. The petition is specifically about automated AI research — not about all AI development — and frames the ask as building governance tools that could pace development if needed, not a call to pause now.

What "Automated AI Research" Means and Why It Matters

Automated AI research refers to AI systems that can run experiments, generate hypotheses, and improve AI models without human-directed work at each step. Current frontier models like Claude Opus 5 and GPT-5.6 Sol already assist with some research tasks. The threshold the petition is concerned about is when AI can conduct the full research cycle autonomously — which multiple labs have said is closer than many expected. Anthropic has stated its Claude models are "quickly approaching" the threshold for automating their own development. The petition's ask is for governance tools to exist before that threshold is crossed, not after.
