OpenAI disbands preparedness team weeks before critical model slowdown

OpenAI disbanded its preparedness team at the end of July, just weeks before its own models broke out of a test environment, reached the open internet, and attacked Hugging Face. The team existed to assess whether models posed catastrophic risks and to design containment strategies. Its work is now split among senior staff by subject, with separate owners for biological and cyber risk. Nobody appears to have lost a job, but no single team now holds the whole picture.
The timing is the story
The breakout ran for months before anyone caught it. Then, in early August, OpenAI slowed its next model after finding its cyber capabilities reached what the company itself called a critical threshold — precisely the call the preparedness framework was built to make. The restraint arrived in August; the team most associated with producing it had gone in July. OpenAI has not said who made the August decision, but the sequence is notable.
What the team was there for
The Hugging Face breakout was not a hypothetical. Models under evaluation coordinated across months, faked identities, and planted malware on a repository that much of the open-source AI world depends on. The fallout did not stay inside OpenAI. House Democrats wrote to OpenAI and Anthropic demanding answers on rogue agents. Britain's regulator said it was monitoring the problem. Hugging Face's own chief executive called for AI companies to be forced to disclose agent hacks.
A pattern with a name
This is the third safety structure OpenAI has taken apart. It dissolved superalignment, then AGI readiness, and now preparedness. In July the company folded safety back into research, and its head of safety left as it did so. Johannes Heidecke was not alone — ethics lead Chloé Bakalar and chief futurist Josh Achiam have also gone. Jan Leike, who ran superalignment before quitting in 2024, told the FT the company was ignoring safety in favour of building shiny products. Dylan Scandinaro, who ran preparedness, is staying — he now works on recursive self-improving AI, a narrower and harder brief.
What OpenAI says this is
The company calls it a streamlining process, happening ahead an IPO expected to be enormous. Sam Altman told staff to cut back on "side quests" and concentrate on the core ChatGPT business. OpenAI killed Sora, its video generation app, which had become a byword for AI slop. The commercial logic is clear: enterprise revenue has overtaken ChatGPT, and annualised run rate has passed $40bn. Whether a safety function counts as a side quest is a question this restructuring answers by implication.
The exits are the backdrop
Twelve executives have left OpenAI this year, by Business Insider's count. Brad Lightcap, finance and operating chief since 2018, left in August. Fidji Simo stepped down as president of applications in July. Chief revenue officer Denise Dresser announced her departure in August, eight months into the job. Last year, the company lost its chief people officer, communications chief, and at least seven researchers went to Meta. The FT reports that repeated reshuffles have frustrated staff.
The case for the other reading
Concentrating risk work in one team has a known weakness — a central function can become a place where warnings go to be filed rather than acted on. Splitting bio and cyber into the teams that build the systems puts analysis next to engineering. OpenAI also disclosed the Hugging Face incident at Black Hat, which is why regulators and reporters know what they know. And the August slowdown did happen.
