nice, I've been looking for something like this! A few notes / wishlist items:

* Looks like for gpt-4 turbo (https://artificialanalysis.ai/models/gpt-4-turbo-1106-previe...), there was a huge latency spike on December 28, which is causing the avg. latency to be very high. Perhaps dropping top and bottom 10% of requests will help with avg (or switch over to median + include variance)

* Adding latency variance would be truly awesome, I've run into issues with some LLM API providers where they've had incredibly high variance, but I haven't seen concrete data across providers
