OpenAI pauses frontier model RL training, plans technical report
JeffLadish · x · 2026-08-19
OpenAI stated in a blog post regarding the Hugging Face incident that as models become more capable, the risks of internal development and testing grow. The company has paused reinforcement learning (RL) training on its latest models intended for deployment for two weeks to harden and red-team research environments and expand monitoring. Its largest planned frontier RL run remains on hold until smaller-scale training and evaluations validate these safeguards and provide more evidence of alignment. A technical report on learnings is expected in the coming weeks.
