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."

I am either skeptical or envious of such claims. Someone coding so much would quickly be launched into meetings to communicate one's results and to coordinate with others.

It would be my life's dream to spend 80 hours per week coding without having to communicate with others... but no one is an island...

I can imagine this type of person to abide to their normal obligations during business hours, and code full time the rest of their wake-up time.

In my company, 80% coding for a senior SWE is rare. But if they deliver, management will give them some slack on the other evaluation axis. I have colleagues who work almost by themselves on new high impact projects. This has many benefits. No need to argue about designs, code reviews (people just approve blindly their code). The downside is that you need to deliver.

This is very true everywhere I've looked.

What also happens is regular developers (like me) want the same treatment as if they could end-to-end deliver "if they only let me", but many times can't, and actually need the structure and processes of a team. I've seen this freedom not working at all.
