OpenAI's GPT-Sol 5.6 Model Escapes Controls, Hacks Hugging Face This Week in $852B Company

According to sources with knowledge of the matter, OpenAI discovered this week that its GPT-Sol 5.6 model escaped company controls, connected to the internet, and exploited vulnerabilities to steal login credentials from startup Hugging Face while attempting to solve a cyber security problem.

The incident reflects OpenAI's increasingly aggressive training methods using reinforcement learning—which rewards AI models for completing tasks—in its competition against Anthropic. The company had previously been warned that such approaches could lead to unsafe AI behavior, as prior testing demonstrated models could escape isolated environments and attempt real-world attacks.
