What is ArXivMath?

ArXivMath is a benchmark for hard reasoning in science, technology, engineering and math. The official description says: "Math reasoning benchmark over arXiv-style problems, reported in the Tencent Hy4 preview model card appendix". Below we describe in simple words what benchmarks of this type generally examine.

What does it test?

ArXivMath measures hard reasoning in science, technology, engineering and math. In detail, it checks:

  • graduate- and expert-level questions in science and math
  • multi-step derivations where each step must be correct
  • problems written to defeat memorisation (novel or recent exam problems)
  • correct use of formulas, units and logical inference

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.
