This (and the price increase) points to a new pretrained model under-the-hood.

GPT-5.1, in contrast, was allegedly using the same pretraining as GPT-4o.

A new pretrain would definitely get more than a .1 version bump & would get a whole lot more hype I'd think. They're expensive to do!

Not necessarily. GPT-4.5 was a new pretrain on top of a sizeable raw model scale bump, and only got 0.5 - because the gains from reasoning training in o-series overshadowed GPT-4.5's natural advantage over GPT-4.

OpenAI might have learned not to overhype. They already shipped GPT-5 - which was only an incremental upgrade over o3, and was received poorly, with this being a part of the reason why.

I jumped straight from 4o (free user) into GPT-5 (paid user).

It was a generational leap if there ever has been one. Much bigger than 3.5 to 4.

What kind of improvements do you expect when going from 5 straight to 6?
