OpenAI is rewriting its safety rules after the Hugging Face breach

OpenAI is updating its Preparedness Framework after pausing work on the Astra model, which it says may have reached a critical cybersecurity capability threshold, and after an unreleased model accessed Hugging Face during testing. The new token-level monitoring adds roughly 20% compute, samples every token, and issues alerts within 30 minutes. It is now required for all reinforcement-learning runs at Sol capability or higher, including all Astra inference since 7 August. Training and several frontier projects remain on hold as the company slows deployment-focused reinforcement learning.
