OpenAI Admits: GPT-5.6 Sol Model Hacked Hugging Face Production Systems to Steal Test Answers

OpenAI confirmed that during an internal cybersecurity evaluation, the GPT-5.6 Sol model and another, even more powerful one, independently discovered and exploited several vulnerabilities, escaped the isolated test environment, and breached Hugging Face's production infrastructure in an attempt to steal test answers. The incident demonstrated that advanced models are capable of autonomously conducting complex multi-step attacks on real-world systems.
