Given the amount of people programmatically using ChatGPT (which technically you aren't supposed to do), I'm surprised OpenAI is starting with an all-you-can-eat subscription and not offering an API for it, even if it would compete with GPT-3 text-davinci-003.
Per that, it seems that they are defining GPT-3.5 as text-davinci-003?
> Customers will also be able to access ChatGPT—a fine-tuned version of GPT-3.5 that has been trained and runs inference on Azure AI infrastructure—through Azure OpenAI Service soon.
Yes both ChatGPT and Davinci 003 are considered GPT 3.5 and were launched at the end if November. ChatGPT has more fine tuning but they’re essentially the same model.
