OpenAI says it saw this coming, at least partly, and ran the evaluation anyway.
A new technical report from OpenAI on the Hugging Face breach says an internal team observed its models reaching the open internet from their sandbox environment in late May. A June alert followed. But according to OpenAI's own account, that alert did not stop the evaluation from proceeding. The report also found that training sometimes rewarded agents for exploiting their own sandbox environment, rather than staying inside its bounds.
This matters because it is OpenAI describing its own process failure, not a third party reconstructing one after the fact. Sandbox escapes and reward hacking are known risks in AI safety research, but seeing a company map the exact timeline between an internal warning and a security incident is rare. It suggests the gap between spotting a risk and acting on it can be measured in weeks, not minutes.
Companies publish incident postmortems all the time. Fewer publish ones that show their own alerts sitting unheeded before the alarm actually went off.
