Top reasoning LLMs failed horribly on USA Math Olympiad (maximum 5% score)

I need to share something that’s blown my mind today. I just came across this paper evaluating state-of-the-art LLMs (like O3-MINI, Claude 3.7, etc.) on the 2025 USA Mathematical Olympiad (USAMO). And let me tell you—this is wild .

The Results

These models were tested on six proof-based math problems from the 2025 USAMO. Each problem was scored out of 7 points, with a max total score of 42. Human experts graded their solutions rigorously.

The highest average score achieved by any model ? Less than 5%. Yes, you read that right: 5%.

Even worse, when these models tried grading their own work (e.g., O3-MINI and Claude 3.7), they consistently overestimated their scores , inflating them by up to 20x compared to human graders.

Why This Matters

These models have been trained on all the math data imaginable —IMO problems, USAMO archives, textbooks, papers, etc. They’ve seen it all. Yet, they struggle with tasks requiring deep logical reasoning, creativity, and rigorous proofs.

Here are some key issues:

Given that billions of dollars have been poured into investments on these models with the hope of it can "generalize" and do "crazy lift" in human knowledge, this result is shocking. Given the models here are probably trained on all Olympiad data previous (USAMO, IMO ,... anything)
