Okay I think there's a familiarity delta. I constantly run into this

I know artificial analysis quite well as the gold standard in llm evals.

But I guess they're still obscure

I didn't think they were.

The age is important because new techniques keep being developed and so it is a very rough indicator of the size/cost/efficiency trade-off.

How old a model is is a major indicator of what you can expect from it.

I really need to develop a better sense for what people know. That's only one of my problems

Thanks for engaging with me
