Recent math benchmarks for large language models (LLMs) such as MathArena indicate that state-of-the-art reasoning models achieve impressive performance on mathematical competitions like AIME, with the leading model, o3-mini, achieving scores comparable to top human competitors. However, these benchmarks evaluate models solely based on final numerical answers, neglecting rigorous reasoning and proof generation which are essential for real-world mathematical tasks. To address this, we introduce the first comprehensive evaluation of full-solution reasoning for challenging mathematical problems. Using expert human annotators, we evaluated several state-of-the-art reasoning models on the six problems from the 2025 USAMO within hours of their release. Our results reveal that all tested models struggled significantly, achieving less than 5% on average. Through detailed analysis of reasoning traces, we identify the most common failure modes and find several unwanted artifacts arising from the optimization strategies employed during model training. Overall, our results suggest that current LLMs are inadequate for rigorous mathematical reasoning tasks, highlighting the need for substantial improvements in reasoning and proof generation capabilities.
“Notably, O3-MINI, despite being one of the best reasoning models, frequently
skipped essential proof steps by labeling them as “trivial”, even when their validity was crucial.”
No prophet worked for free and they were always near the rullers and near big money. The story repeats itself, just the times are different and we can instant message with each other.
This study is bullshit, because they only trace evaluations and not trace training process that align tokens with probabilities.
remember, if we look too closely at the magic box,
we might notice how we’ve been fooledthe box will stop magicing for us!Well, every civilisation needs it’s prophets. Our civilisation built prophet machines that will kill us. We just didn’t get to the killing step yet.
yeah but see, these grifters all heard it as “every civilisation needs its profits”. just a shame they suck at that too
