GPT5 pre-training just ended I believe. Brock, Pachocki, Szymon Sidor, would have likely all been involved.

These are huge losses. Pachocki led pre-training for GPT-4, and probably GPT-5. Brockman is the major engineer responsible for the efficiency improvements that enabled ChatGPT and GPT-4 to be even remotely cost-effective. That is a piece that is often overlooked, but OpenAI's advantage over the competition in compute efficiency is probably even larger than the model itself.

Do you have a source that they just finished GPT-5 pre training or is that just speculation.
