Nice benchmark but the human comparison is a little lacking. They claim to have surveyed 19 experts, though the vast majority of them have only a master's degree. This would be akin to comparing LLM programming expertise to a sample of programmers with less than 5 years of experience.

I'm also not sure it's a fair comparison to average human results like that. If you quiz physicians on a broad variety of topics, you shouldn't expect cardiologists to know that much about neurology and vice-versa. This is what they did here, it seems.
