This is an embarrassing overreach. We don't even have models that can win the far easier AMC, let alone AIME, USAMO, and then IMO.
What is AMC AIME, USAMO ?
AMC = multiple choice test, open to all grade school students.
AIME = open response test, all answers are numerical, open to students who score high enough on AMC only.
USAMO = USA Math Olympiad. IMO-style proof problems. Open only to top N scorers on AMC and AIME.
