I don't think it's available to everyone yet on 4o. Just like you I am getting the same "cartoony" styling and poor text generation.

Might take a day or two before it's available in general.

So far it seems to be the same for me.

It seems like an odd way to name/announce it, there's nothing obvious to distinguish it from what was already there (i.e. 4o making images) so I have no idea if there is a UI change to look for, or just keep trying stuff until it seems better?

If only OpenAI would dogfood their own product and use ChatGPT to make different choices with marketing that are less confusing than whoever's driving that bus now.

This is OpenAI's bread and butter - announce something as though it's being launched and then proceed to slowly roll it out after a couple of days.

Truly infuriating, especially when it's something like this that makes it tough to tell if the feature is even enabled.

They're also copying the Apple and Google style of refusing to show which version of the product you're using.
