OpenAI hit the brakes. Now what?
Why it matters
OpenAI's decision to pause reinforcement learning training on its latest models and delay its largest frontier RL run signals a strategic shift toward safety over speed—with major implications for how the frontier labs compete and how practitioners think about capability timelines.
