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."

Seriously, do we honestly believe 80 hours a week coding is a good thing. What, is he this bad at coding.

What about he spends 4 hours a week coding cause he’s so good at coding.

Way more impressive.

Might as well add LOC as a metric. Both can mean the person is extremely inefficient, over-engineering everything, and their eyes are begging for a break.

However! The best engineers I've been around do work a lot and they like it.
