First mention in chats for me was September 2016. Not sure how that topic came up but LLMs aren't the only way to get there. It's also a rather obvious principle to come up with, at least I'm pretty sure I was doing it without thinking I should name the concept of picking the option that best fits your requirements
I think the one from hugging face is much clearer, albeit its an arena metric and a bit tricky to find the pareto view. Look for the the top Navigation Bar
(Agent Chat Code Image Video). Chat -> (dropdown) Text -> (Side panel) View as Pareto.
