O1, R1, etc. are so good that we evaluate them on “PhD-level” benchmarks. But, these benchmarks are so hard that most people can’t even understand what they are testing. We’ve built a benchmark with problems that are hard to solve but easy to verify: for both humans and models.

Ugh, who did this? @joepolitz.bsky.social ? Wait, was it @dbp.bsky.social ? Someone else from @shriram.bsky.social's group? Also from "Humanity's Last Exam".

Counterintuitively, this shows the power of GC. IIRC I've heard of similar tricks used for high-performance OCaml at Jane Street.
