OpenAI hardly released gpt-4o. The demo yesterday was clearly a rushed response to I/O. It’s quite possible that Google will ship multi-modality features faster than OpenAI will.
All my apps are updated in the App Store too.
Website also only has toggle for 3.5 and 4 with the Plus upgrade. Not sure if it's cause I'm in Canada?
Edit - it does list the new model in my app at least
The bigger issue is that 4o without the multi-modal, new speech capabilities or desktop app isn't that different to GPT-4. And those things aren't yet launched.
look at their linkedin pages, that will tell you why they are desperate
(hint: they bought OpenAI bags on the secondary market)
"We have no moat" swings both ways.
