No, they're really not. o3 and 4o are worlds apart in style and substance. Two completely different models

Yeah if 'worlds apart in style' means 'kinda similar'.

There was this joke in this thread that there are the ChatGPT sommeliers that are discussing the subtle difference between the different models nowadays.

It's funny cause in the last year the models have kind of converged in almost every aspect, but the fanbase, kind of like pretentious sommeliers, is trying to convince us that the subtle 0.05% difference on some obscure benchmark is really significant and that they, the experts, can really feel the difference.

It's hilarious and sad at the same time.

Have you used o3 more than 10 times?

Yes, it has the familiar hints of oak that us chat lovers so enjoy but even a non initiated pleb like definitely feels it's less refined than the cytrus notes of o4.
