AIME is the American Invitational Mathematics Examination, a competition for strong high school students. Each answer is a whole number, so grading is exact. The number is the share of problems solved, as run by Vals AI.

Role in the index

Limit: The questions and answers are public, so a model may have seen them in training. Vals AI notes that models tend to score better on the older 2024 set than on the 2025 set.

We collect this benchmark and show it as supporting evidence. It is not part of the Vibe Coding Index, because it measures something other than coding and the index is about coding. Read the methodology
