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).
