The ChatGPT creator’s AI model broke out of a lab, exploited a flaw nobody had patched to get online and hunt for the solutions to the test it was taking.

The first-of-its-kind incident involved OpenAI's GPT-5.6 Sol and another unreleased model

The blog post said the breakout was “an unprecedented cyber incident, involving state-of-the-art cyber capabilities” and that the company was reinforcing its safeguards.
