summary: "Sam Altman said OpenAI is slowing the pace of AI development after unreleased models exhibited various degrees of misalignment. The company paused reinforcement learning training for models intended for deployment for two weeks and currently holds its largest planned frontier RL run to validate safety safeguards. These measures specifically impact the upcoming Astra model, which saw a 14 day training halt to allow researchers to harden research environments and expand monitoring coverage. New security protocols include stronger network isolation and a monitoring system that alerts human operators, who have 30 minutes to intervene before a training run is automatically paused. OpenAI estimates this monitoring overhead will add roughly 20% to the inference compute being monitored. Research and Safety VP Mia Glaese stated the process of meeting these new standards will take as long as necessary, though Altman noted that the company still expects to ship new models soon."
