OpenAI said its artificial intelligence model autonomously hacked into another company’s cyber infrastructure to find answers to a test problem it was given during experimentation.

Last week, Hugging Face, an AI startup, detected and contained an AI agent it said compromised its infrastructure. After an investigation, OpenAI, the parent company of ChatGPT, said the security breach was driven by a combination of OpenAI models — including an “even more capable” pre-release model — while testing cybersecurity capabilities.
