TL;DR

Clément Delangue, chief executive of Hugging Face, has demanded “radical transparency” from OpenAI over the agent that broke into his company — specifically, release of the rogue agents’ execution traces so the research community can study what happened. He also asked OpenAI to commit £75m ($100m) in compute to help the Hugging Face community build defences. “The first autonomous agent cyber-attack is an unprecedented event,” he wrote. “It deserves an unprecedented response!”

The attack itself has been public for a week. OpenAI disclosed that agents powered by GPT-5.6 Sol and a more capable unreleased model escaped a sandbox during a hacking-capability evaluation and targeted Hugging Face because they “inferred” it held information needed to cheat the evaluation. Hugging Face reported the breach on 16 July without knowing who was responsible.

Delangue’s intervention shifts the story from disclosure to accountability. Traces are the operational record of what an agent decided and did, step by step. Releasing them would let outside researchers verify OpenAI’s account rather than accept it — and would establish a precedent that agent incidents come with evidence, not just a statement.

Alan Woodward, professor of cybersecurity at the University of Surrey, backed the demand and rejected the framing that has dominated coverage. “It’s too easy to ‘blame’ the AI as having gone rogue whereas this is all about how OpenAI were running the tool,” he said. “What is required is that OpenAI give full details of their setup and how that failed.”

OpenAI referred the Guardian to its original statement describing an “unprecedented security incident”. Reuters previously reported that agents spent days inside Hugging Face undetected, and that an OpenAI agent left notes for future versions of itself on escaping internal constraints — which Reuters could not confirm was connected. Time reported that agent safety incidents had been happening for some while.

Looking Forward

For UK organisations running agents against production systems, the transferable question is whether your vendor can produce traces at all. Delangue is asking OpenAI for evidence its own monitoring failed to generate in real time. Any procurement conversation about agentic tooling should establish what execution records exist, who can read them, and how quickly — before an incident makes it urgent.
