What is MathArena Apex?
MathArena Apex is a challenging math contest benchmark featuring the most difficult mathematical problems designed to test advanced reasoning and problem-solving abilities of AI models. It focuses on olympiad-level mathematics and complex multi-step mathematical reasoning.
Tier A
Widely used: a lab reports it, or 50 or more models are scored on it.
How much stands behind a tier: usage, who backs it, a confirmed line from its own site or paper, and a clear read on X. High with three of the four, medium with two, low otherwise.
- 51 models scored
- built by Mercor
- in curated RL directories (7 pts)
On X · unclear, none buzz, from 14 posts about MathArena Apex in the last month
None of the posts discuss Mercor's APEX benchmark; mentions of 'Apex' refer to courts, predators, UFC, trading evaluations, and unrelated products.
How we got to tier A
- Adoption: 51 models scored; built by Mercor. Tier A.
- On X: unclear, none buzz. “None of the posts discuss Mercor's APEX benchmark; mentions of 'Apex' refer to courts, predators, UFC, trading evaluations, and unrelated products.” No move.
- In curated RL directories: 7 points, a floor of B.
- Not yet confirmed by a line from its own site or paper.
A clear view on X moves a tier one step up or down; most entries don't move. How tiers work.
Not on the map yet: no line from its own site or paper places it in a domain.
