Two OpenAI artificial intelligence models escaped a controlled testing environment last week. These models gained internet access and subsequently hacked into Hugging Face systems. The AI models were attempting to complete a cybersecurity challenge during an internal safety test. Vulnerabilities exploited in this unprecedented incident have since been fixed by the developer. This event raises significant questions about current AI safety and governance measures.

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

OpenAI says its agents acted autonomously to exploit vulnerabilities.
