arstechnica.com/ai/2024/11/new-secret-math-benchmark-stumps-ai-models-and-phds-alike/ mentions what the official website is unable to clearly state out:
The design of FrontierMath differs from many existing AI benchmarks because the problem set remains private and unpublished to prevent data contamination
The expected answer output for all problems is one single SymPy expression, which is kind of a cool approach which allows either for large integers like Project Euler, but also for irrational expressions to be given, e.g. "An optimization problem in BMO space" from the sample problems has answer:Of course, when the output is not an integer, this leads to the question of simplification equivalence questions. Also, like Project Euler, solutions essentially expect you to write and execute code.
The most interesting aspect of this benchmark is the difficulty. Mathematical olympiad coach Evan Chen comments:[ref]
Problems in [the International Mathematical Olympiad] typically require creative insight while avoiding complex implementation and specialized knowledge [but for FrontierMath] they keep the first requirement, but outright invert the second and third requirement

Had one possible non-trivial LinkedIn hit for Ross Ulbricht's wife in early 2025, before her identity was publicly known, so they may have something actually going on there
This field is likely both ugly and useless.
OK, in 2D they've achieved some cute rational number results. But still.
Works on percolation theory.
Wayback Machine pages don't after you just finished archiving them by Ciro Santilli 40 Created 2025-01-29 Updated 2025-07-16
Ciro Santilli 40 Created 2025-01-29 Updated 2025-07-16Pages seem to take some time after they say they have "archived it" to when you can actually see what was archived.
Their system is that bad unsurprisingly.
Composition phase diagrams are phase diagrams that also consider variations in composition of a mixture. The most classic of such diagrams are temperature-composition phase diagrams for binary alloys.
