OpenAI announced it has temporarily paused reinforcement learning (RL) training on its latest frontier models for two weeks. The halt is intended to harden research environments, expand red-teaming efforts, and increase monitoring coverage. The largest planned frontier RL run remains on hold pending validation of safeguards and alignment evidence through smaller-scale training.
