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.

"Greg Brockman works 60 to 100 hours per week, and spends around 80% of the time coding. Former colleagues have described him as the hardest-working person at OpenAI."

This is like a supervillain origin story, Greg and Sam are 100 % going to start something new now, even if it's just out of spite with how much both seem to have liked their work at OpenAI

Would they even be able to compete with OpenAI at this point? Even without Greg and Sam they have Ilya, the models they've trained so far, institutional knowledge, datasets and billions from Microsoft. Could OpenAI be at escape velocity anyway to AGI just continuing on the track it's been on?

Could a nuclear energy company be at escape velocity to fusion because they are the best at fission? I wouldn't think so
