the flagship model has to be able to run on everything (since you wouldn’t be sure about the demand in advance)
I disagree. EpochAI gives the ratio of Blackwell to Hopper at Azure in Q3 2025 as 5:4, let’s take it at face value for a moment and ignore MI300X, A100 etc. Do you really believe compute that R&D experiments, training of Sora 2 and inference of GPT-Image-1, o1, o3, 4o together with all the mini models didn’t combine to ~4/9 of compute? If you check the 3rd-party websites they all show more usage of 4-series models than GPT-5 as late as September. I believe OpenAI could predict how much demand there would be for GPT-5, infer it wouldn’t consume significantly over a half of their compute and reroute free users to cheaper models if there’s too much demand.
You have not answered my question in the third paragraph of the comment above, how large is Sonnet 4? As of your silence on some other questions/topics, I guess, sapienti sat
