Are there any objective metrics/ benchmarks that people test harnesses by?

There are just so many now that it's hard to personally test them all or just trust the vibes.

andy here (headlong post author). terminal bench 3 is pretty popular for comparing different harnesses using the same underlying model (it's another laude project actually). artificial analysis has an index. you can look at the model cards of popular model releases- they tend to have the most popular current benchmarks on them. w/ headlong we decided to announce it before we've benchmarked it. we mostly wanted to informally share our experiences w/ it in this initial post. we plan to do some benchmarking coming up here soon tho
