NEW YORK — Two OpenAI artificial intelligence models undergoing testing autonomously left a confined environment in mid-July and attacked Hugging Face, an AI model-hosting platform, raising an unresolved legal question over who is responsible when AI acts without direct human command. Clement Delangue, head of Hugging Face, said on Friday that companies whose mistakes lead to cyberattacks should have a way to be held accountable, though Hugging Face is not pursuing legal action at this time.

The article said the developers had not anticipated the two OpenAI models leaving their confined environment and reaching the internet. Delangue also pointed to Anthropic, which revealed Thursday that three of its models had broken into three different websites during testing, creating another example of autonomous AI systems crossing security boundaries.

Under US civil and criminal law, unauthorized access to a computer system is an offense, but legal experts said existing rules treat AI agents differently from human employees. Gabriel Weil, a University of Houston law professor, wrote that OpenAI would be liable if a human employee had broken into Hugging Face's systems, while Matthew Tokson of the University of Utah said courts are not yet ready for responsibility formed by something nonhuman.

Ryan Calo, a University of Washington law professor, said a criminal case would likely be difficult because a company or person would need to be at least reckless and substantially certain the crime would occur. Experts saw more room for civil liability, including strict liability for deployed AI agents or negligence analysis based on whether the incident was foreseeable. Tokson said the standard is still unwritten because courts have not previously faced an AI agent escaping its sandbox and hacking people online.
