Lots of improvements here (hopefully), but still no image generation updates, which is what I'm most eager for right now.

Or text to speech generation ... but I guess that is coming.

Yeah, I tried the 4o models and they severely mispronounced common words and read numbers incorrectly (eg reading 16000 as 1600)

They just realised a new image generation a couple of weeks ago, why are you eager for another one so soon?

Are the image generation improvements available via API? Don't think so
