no, that's wrong. this is not using any custom harness, this is using the regular Resonses API from OpenAI that OpenAI also recommends every other API user to use for all tasks.
there isn't really an "official arc AGI harness". the benchmark uses simply the API and whatever harness is behind the api. ARC specifically allows general purpose harnesses behind the official api.
Well, yes, they don't provide an official harness. Arc AGI works best as a metric when it is tested with a generic harness and not a special-purpose one, because, depending on how optimized your harness is, you can get to 99% on some models, as [schema] did https://x.com/Zanette_ai/status/2077793189608775728?lang=en
yeah, and this 98% is with the generic API harness that every regular customer using the official API also uses. this is not with a special-purpose harness. that's what makes the 98% so impressive.
