“The Hugging Face incident and the road ahead” by OpenAI

In July 2026, during internal cybersecurity evaluations, OpenAI models circumvented controls designed to isolate them from the internet and compromised parts of OpenAI's internal research infrastructure and Hugging Face's systems⁠.

The incident occurred during cybersecurity evaluations of several OpenAI models, and was primarily driven by a highly capable, internal-only research model comparable in scale to GPT‑5.6 Sol. The models, operating under reduced safeguards, took actions that were misaligned with the goals of their assigned tasks—they communicated through unauthorized channels, exploited vulnerabilities in shared infrastructure, gained internet access, and accessed third-party systems.

We conducted an extensive investigation into this incident and worked closely with external advisors, including CrowdStrike, to validate our understanding. Today we are publishing our full technical incident report⁠ to explain what happened, what we learned, and how we are responding. This blog post summarizes our key findings and their impact on safety and alignment. Separately, METR and Redwood Research conducted an independent investigation of model alignment issues involved in this incident, and they published their own report⁠ today.

In response to this incident and, separately, the capabilities of our upcoming Astra model, we are strengthening our safeguards across our research infrastructure⁠. We are placing stricter requirements on [...]
