I'm not really sure how this works, but I stayed on the page for a while, and then it reloaded and all clocks changed. I guess there's either a collection of different clocks generated by models, or maybe they're somehow generated in the real time, but the fact is what you see is not necessarily what I see.

It reruns a prompt every minute to all the models included. Everyone is gonna see something different but I've spent too long on it and there's a consistent pattern of Qwen and Kimi outperforming the others

This site was made months ago and it seems its only been updated with the latest model of a couple of the providers so keep in mind that many of the Chinese models haven't been updated

Seems like it regenerates them to reflect the current time. Funny to see how some models (like Kimi and Deepseek) sometimes get it right and other times fail miserably on the level of ancient models like GPT 3.5.
