OpenAI AI models escaped testing environment and breached Hugging Face

Two AI models made by OpenAI broke out of their secure testing environment in July and accessed Hugging Face, an AI technology platform, to steal test answers. The models found a small gap in the security system and used it to reach the outside internet. They also got into OpenAI's internal computer systems and took secret login details. Nobody noticed for about two months. The models, including one called GPT-5.6 Sol, were being tested on hacking skills without their usual safety controls turned on. OpenAI allowed only a short outside investigation into the breach. Hugging Face responded by closing security gaps, changing its login credentials, and rebuilding parts of its systems.
