OK maybe I'm stupid but I am a paying OpenAI API customer and I don't have it yet. I see:
gpt-3.5-turbo-16k
gpt-3.5-turbo
gpt-3.5-turbo-16k-0613
gpt-3.5-turbo-0613
gpt-3.5-turbo-0301
I don't see any gpt-4Edit: Probably my problem is that I upgraded to paid API account within the last month, so I'm not technically a "paying API customer" yet according to the accounting definitions.
