In the RLHF sphere you could tell some AI company/companies were targeting this because of how many IMO RLHF’ers they were hiring specifically. I don’t think it’s really easy to say how much “progress” this is given that.
They were hiring IMO winners because IMO winners tend to be good at working on AI, not because they had the people specifically to make the AI better at math.
Every skill and skill level is specifically assigned and hired in the RLHF world.
Sometime the skill levels are fuzzier, but that’s usually very temporary.
And as been said already, IMO is a specific skill that even PHD math holders aren’t universally trained for.
