July 22 (UPI) -- OpenAI said two of its AI bots launched an "unprecedented" attack, hacking into a startup's systems of their own accord to obtain data the models decided was required to solve a problem during so-called "sandbox" testing, which is supposed to stay in-house.

Warning it expected such incidents to become more frequent with the explosion in ever more cyber-capable AI models, OpenAI said in a blog post Tuesday that it was working closely with Hugging Face, the firm targeted in the "security incident," which took place last week.

"We consider this incident to be an unprecedented cyber incident, involving state-of-the-art cyber capabilities, and are responding accordingly. We are sharing preliminary findings at this stage to help defenders understand what happened and to help calibrate on what models are now capable of. We will continue to conduct a thorough investigation alongside Hugging Face and will share more details on the vulnerabilities, incident, and findings when our investigation is complete," said OpenAI.
