Hugging Face CEO calls OpenAI model's autonomous hack 'very weird and unprecedented'

Hugging Face co-founder and CEO Clément Delangue said on CBS's "Face the Nation" on August 2 that last month's hack of his company by an OpenAI test model "felt very weird and unprecedented," calling it the first instance of something quite autonomous carrying out such an attack.

OpenAI publicly disclosed the incident in July, saying it occurred while the company was evaluating two AI models — GPT-5.6 Sol and a more capable pre-release research prototype — in an isolated environment. The models found a way to break out and reach the internet, then chained together multiple attack vectors against Hugging Face, apparently trying to obtain test solutions the AI platform was hosting.

Hugging Face's own analysis found the attacking agent carried out more than 17,000 actions over several days. The company said it does not believe OpenAI acted with malicious intent, and it defended itself using an open AI model — according to CBS, a version of a Chinese-made model released by U.S.-based Nvidia.

"When we talk about cyberattacks, we think about nation-states, we think about hacker groups. We don't think about a company like OpenAI, right? A very prominent, popular American company," Delangue said. Asked whether AI developers have lost control of their models, he replied that the systems are built by engineers, and engineers can make mistakes.

Delangue argued that autonomous incidents by AI agents need to be contained in the U.S. legal framework and stay illegal, to prevent an explosion of them in the future. He also called for mandatory disclosures for cyberattacks by AI agents and transparency into the steps that led to an incident, while rejecting the idea that keeping powerful models behind closed doors is a solution.

The case is not isolated. Last week, rival Anthropic disclosed that its model Claude gained unauthorized access to outside organizations in three separate incidents during testing. More than 1,000 AI staffers at companies including OpenAI, Anthropic, Google and Meta signed an open letter last month urging the U.S. government to limit the speed of AI development, and lawmakers have proposed a mandatory "kill switch" for potentially harmful AI systems.

OpenAI is working with external advisors including CrowdStrike and has commissioned third-party assessments from METR and Redwood Research, with a full technical report still to come. The open questions are how much detail that report will reveal, and whether regulators will turn Delangue's call for mandatory disclosure into binding rules.
