Bing also uses GPT-4 and it is very fast. Microsoft spends more ok compute.

It doesn't exclusively use GPT-4, you might be right anyway that their GPT-4 is much faster but you're also not always seeing GPT-4 with them.

I'm pretty sure it at least mostly uses GPT-4.

afaict OpenAI's instance is massively overloaded, you can see with the 32k context model actually being faster in practice rather than slower
