Isn't this factually wrong? Grok-4 used as much compute on RL as they did on pre-training. I'm sure GPT-5 was the same (or even more)

It was true for models up to o3, but there isn't enough public info to say much about GPT-5. Grok 4 seems to be the first major model that scaled RL compute 10x to near pre-training effort.
