They did this on the far easier training set though?
An alternative story is they trained until a model was found that could beat the training set but many other benchmarks too, implying that there may be some general intelligence factor there. Maybe this is still goodharting on benchmarks but there’s probably truly something there.
There are degrees of Goodharting. It’s not Goodharting to ARC-AGI specifically, but it is optimizing for performance on the array of easily-checkable benchmarks. Which plausibly have some common factor between them to which you could “Goodhart”; i. e., a way to get good at them without actually training generality.
