AIME 2025 I
Mathematics
The 15 problems of AIME I 2025. As one of the newest competition sets available, it leaves the least room for training-data contamination, and reading it beside the 2024 set makes that effect visible.

What a problem looks like
One competition problem statement. The integer answer is not part of the prompt.
How it is scored
The source ships the integer answer with every problem; this catalogue keeps it in restricted storage and never renders it.
Why it is hard
Same demand as any AIME paper — an exact integer after a long construction — with the added property that the problems postdate most training corpora.
