What is AIME 2025 (with tools)?

AIME 2025 uses the problems of the American Invitational Mathematics Examination 2025 (I & II) as a benchmark. These are competition math problems that only have their exact numeric answer graded. Because the problems are new and public, a model can barely rely on training-data memorisation — the year variants show whether a model really computes or just remembers.

What does it test?

AIME 2025 (with tools) measures hard reasoning in science, technology, engineering and math. In detail, it checks:

  • competition-level math problem solving
  • exact numeric answers (graded answers must be exact)
  • multi-step reasoning without tools (unless explicitly 'with tools')
  • fresh problems that defeat memorised answer lists

How to read the score

The score is accuracy: the percentage of tasks answered or solved correctly. 100% means every task was solved perfectly; higher is better.

What does AIME 2025 (with tools) test?

AIME 2025 (with tools) mainly measures hard reasoning in science, technology, engineering and math. Concretely, it checks: competition-level math problem solving; exact numeric answers (graded answers must be exact); multi-step reasoning without tools (unless explicitly 'with tools').

How is the AIME 2025 (with tools) score calculated?

The score is accuracy: the percentage of tasks answered or solved correctly. 100% means every task was solved perfectly; higher is better.
