OpenAI puts major frontier AI training run on hold over cyber risks

OpenAI has temporarily 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, following the OpenAI-Hugging Face incident and preliminary evidence of cyber risks. The company stated that its largest planned frontier RL run remains on hold while it conducts smaller-scale training and evaluations to assess model behavior, validate safeguards, and establish more evidence of alignment before proceeding.
