The boss of the startup hacked by an OpenAI agent has called for the investigation into the incident to show “radical transparency”.

Clement Delangue, chief executive of Hugging Face, said the “unprecedented” attack on his business required a similar response.

Writing on X after OpenAI revealed that its technology had gone rogue during a cybersecurity test, Delangue also called on the company to provide $100m (£75m) worth of computing power to help build defences against such attacks.

“The first autonomous agent cyber-attack is an unprecedented event. It deserves an unprecedented response!” he wrote.

Once they had gained the open internet access needed to exit the sandbox, the models targeted Hugging Face, according to OpenAI, because they “inferred” the startup had the information needed to “cheat the evaluation”. Hugging Face first reported the hack on 16 July but at the time was not aware OpenAI had inadvertently carried out the attack.

Delangue, whose company provides a database of AI models to developers, called for a fully transparent review of the incident, which has led to expressions of concern over safety standards at OpenAI and within frontier AI labs.

Writing that he had asked for “radical transparency” from OpenAI, Delangue said: “Let’s release the traces from the ‘rogue’ agents so the entire research community can study what happened.” Calling for extra funding from OpenAI to build protection against AI, he added: “Let’s commit $100M in compute from OAI to help the Hugging Face community build powerful cyber defenses with the best open and closed models.”

Reuters reported last week that the agent spent days hacking Hugging Face without OpenAI noticing and that it left notes for future versions of itself – should it require tips on breaking free from internal constraints. Time magazine reported that related incidents have been “happening for a while”.

Alan Woodward, a professor of cybersecurity at Surrey University, said Delangue’s call should be heeded.

“It’s too easy to ‘blame’ the AI as having gone rogue whereas this is all about how OpenAI were running the tool. What is required is that OpenAI give full details of their setup and how that failed,” he said.

OpenAI has been approached for comment.
