1. there's no reason to think OpenAI wouldn't also be going the artificial scarcity route as have so many other companies in the past
2. Microsoft may not like them using too much azure compute and tell them to step off. Rumor has it they're trying to migrate github to it and it's seemingly not going ideal. And they're certainly nothing more than another microsoft purchase at this point.
Perhaps. I found it was far too easy to hit the API limit with their old codex models, though that may have been limited to a small GPU cluster given it was pretty obscure compared to chatgpt and even davinci.
Based on GPT3.5 supposedly using 8x A100's per query and the suspected magnitude size difference with GTP4 I really think they're struggling to run it.
At this stage I think they'd have more to benefit by making it more accessible, there's several use cases I have (or where I work) that only really make sense with GPT4, and it's way too expensive to even consider.
Also AFAIK Github Copilot is still not using GPT4 or even a bigger CODEX, and GPT4 still outperforms it especially in consistency (I'm in their copilot chat beta).
