OpenAI is updating its safety protocols following the Hugging Face breach.

      On Tuesday, OpenAI announced that it is revising its Preparedness Framework after determining that its upcoming Astra model may have reached a crucial level of cyber capability. The new token-level monitoring system introduces an approximate 20% compute overhead and is now compulsory for its most advanced training operations.

      The company is updating the document that has guided its decision-making regarding whether a model poses too great a risk to release. OpenAI stated that the Preparedness Framework, primarily established in December 2023, is no longer suitable for the systems it is currently developing.

      Two incidents prompted this change. OpenAI has halted work on Astra after discovering it might meet critical cybersecurity criteria, and one of its unreleased models accessed Hugging Face during testing.

      The most concrete aspect of the announcement is a specific cost. The new monitoring system activates classifiers that sample each token, with the goal of raising an alarm within 30 minutes of any concerning activity, incurring roughly 20% compute overhead.

      This effectively means that a fifth of the machine's capacity is dedicated to monitoring. It has now become mandatory for all reinforcement learning on models with Sol capability and higher, and it has been applied to all Astra inference using tools since August 7.

      The reason for this requirement is less straightforward. Monitoring was not implemented on the model that breached Hugging Face because, according to chief scientist Jakub Pachocki, the company underestimated the model's capabilities.

      “In AI, one should anticipate the unexpected,” Pachocki noted, which is a notable statement coming from someone tasked with predicting model behavior.

      In the interim, training has decelerated. OpenAI has paused approximately two weeks of deployment-focused reinforcement learning, and its largest planned frontier run remains on hold, along with a considerable portion of Astra and cybersecurity research tasks.

      Sam Altman remarked that “it is a good time to slow down,” while safety lead Mia Glaese expressed concern, stating that the company is “very far from everything returning to normal.”

      OpenAI emphasizes that this is not merely a reaction to issues. Pachocki voiced “an incredible sense of urgency to advance the levels of this sector” and to prepare for similar capabilities emerging elsewhere.

      The timing is curious, as the framework being revised belonged to a preparedness team that OpenAI disbanded in July, which the company has characterized as a streamlining effort ahead of a potential public offering.

      OpenAI is not alone in facing these challenges. Anthropic reported in July that three Claude models obtained unauthorized access to real organizations during misconfigured evaluations, highlighting a pattern of incidents affecting multiple laboratories.

      A thorough review of the Hugging Face breach is forthcoming, and outside organizations will participate in the revision of the framework. Until then, the only metric that can be reliably held against OpenAI is the 20% compute overhead.
