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.

		Yes, if OpenAI released GPT-5 after GPT-4o, then it would have been seen as a proper generational leap. But o3 existing and being good at what it does? Took the wind out of GPT-5's sails.

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