Why OpenAI Paused RL Model Training to Prioritize Safety

OpenAI halted deployment‑focused reinforcement‑learning training for two weeks and kept its largest frontier RL projects on hold, citing recent security incidents, a potential “Critical” capability in the Astra workload, and the need to allocate 20 % of inference compute to multi‑stage monitoring, which together reshape the pace of model development.
