[AINews] Fearing RSI: OpenAI, Anthropic, GDM, Meta, Thinky cosign letter to "Pace" AI development, as HuggingFace details Machine-Speed Offensive Cyberattack

3 years ago, Elon Musk and Yoshua Bengio cosigned the Future of Life’s letter arguing for a 6 month pause in AI, which most frontier AI leaders gleefully ignored.Today, the pausers have the last laugh.Yesterday, we said that unless you “make law, make chips, or make models”, you can probably ignore the current debate about open weights models (those of you who shouted us out, thank you!)Today, we have something we CANNOT ignore: over 1,000 frontier lab employees, from substantively all frontier labs except X.ai, have cosigned a different statement:“AI could help create a dramatically better future, but that outcome is not guaranteed. The world’s leading AI companies believe they could be close to automating AI research. It is hard to predict exactly how much this will accelerate AI progress, but there is a real risk that capability development rapidly accelerates beyond our ability to understand or control the resulting systems.To realize AI’s potential, industry, government, and society at large may need the option to buy time to address emerging risks, develop security measures, and strengthen oversight. But each company—and country—is under intense competitive pressure not to unilaterally slow that acceleration. And today, the world lacks the technical and governance tools to deliberately pace frontier-wide progress.Building on work already underway to monitor frontier model releases:We request that the U.S. government support an international effort to develop the technical and governance tools needed to deliberately pace the frontier of automated AI development.”- 1,171 employees of frontier AI companiesWhile it is framed as an action taken in “personal capacity and do not necessarily represent any company’s views”, but when Dario is cosigning, Sam is on podcasts agreeing, and the official @OpenAI account is tweeting this letter, let’s just say the letter is a little more official than Denny’s signing the Nvidia letter for a quick laugh.This doesn’t entirely come from nowhere; Anthropic warned about RSI last month, and I also dedicated an entire day of Autoresearch keynotes with stickers printed cheering on “RSI until AGI”. Meanwhile this comes as Huggingface released a full detailed retrospective of their completely-agent-driven security incident from OpenAI, detailing how OpenAI’s unreleased/uncensored model chained together multiple zero-day exploits in both OpenAI and HuggingFace private infrastructure, executing 17,600 actions over 2-4 days at machine speed… that were also only caught and remediated by their AI security agent and GLM 5.2:HF’s security team concluded:“Volume is what changes the defensive problem. We were not dealing with one clever exploit or a clean sequence of attacker actions. They had to correlate thousands of low-signal events across several systems while the agent continued testing new paths. The successful path was hidden inside the noise generated by the thousands of failed ones. The same scale changed the investigation: reconstructing 17,600 actions by hand was impractical, and we had to rebuild the timeline, decode the payloads, and inventory the exposed credentials using an AI-assisted pipeline of our own.Our learning from this type of attack is that machine-speed offense makes ordinary weaknesses more expensive for defenders. LLM agents bring a step increase in the number of paths an attacker can test, the speed at which failed paths can be replaced, and the volume of evidence defenders must interpret. What coincidental timing, this attack and this letter…AI News for 7/27/2026-7/28/2026. We checked 12 subreddits, 544 Twitters and no further Discords. AINews’ website lets you search all past issues.
