In the authors’ words
We introduce FrontierMath, a benchmark of hundreds of original, exceptionally challenging mathematics problems crafted and vetted by expert mathematicians. The questions cover most major branches of modern mathematics – from computationally intensive problems in number theory and real analysis to abstract questions in algebraic geometry and category theory. Solving a typical problem requires multiple hours of effort from a researcher in the relevant branch of mathematics, and for the upper end questions, multiple days. FrontierMath uses new, unpublished problems and automated verification to reliably evaluate models while minimizing risk of data contamination. Current state-of-the-art AI models solve under 2% of problems, revealing a vast gap between AI capabilities and the prowess of the mathematical community. As AI systems advance toward expert-level mathematical abilities, FrontierMath offers a rigorous testbed that quantifies their progress.
Claude Fable 5.2 leads with 95.1%
Best score per entry from the benchmark's own leaderboard, read on November 12th, 2026. Where a model ran with several settings or harnesses, we keep its best. Every run is in the next chart. Names in gray aren't in our model list: fine-tunes, agent systems, products and older models. They don't count toward leaders.
Claude Fable 5.2 leads with 95.1% across all independent runs
Best score per model across the official leaderboard, Epoch AI’s own runs and any board Epoch AI copied. Each bar and row names its source.

5 models have held number one on the official leaderboard since its release in June 2026 5 models have held number one across all independent runs since its release in June 2026
Lab claims count from the day the card came out, independent runs from the model’s release. We draw one row each for the benchmark’s own leaderboard, Epoch AI’s runs and what labs claim in their cards.

GPT-5.5 Pro on the official leaderboard passed 85% in April 2026
All the scores we have, one dot each, so a model tested at several settings appears more than once.

One lab put it in a launch post in the last six months
Launch posts from every lab that has listed it, one tick per post. Tall colored ticks include it, and short gray ones leave it out.
| Date | Launch post | Score | As the post writes it |
|---|---|---|---|
| Jul 9, 2026 | GPT-5.6 Luna | 78.6 | FrontierMath Tier 1-3 (v2) |
| Jul 9, 2026 | GPT-5.6 Terra | 84.9 | FrontierMath Tier 1-3 (v2) |
| Jul 9, 2026 | GPT-5.6 Sol | 89 | FrontierMath Tier 1-3 (v2) |
The lab's number comes out ahead in 0 of 2 pairs that differ
Each score a lab reported for its own model, beside the same model's best score on the leaderboard. Gaps mostly come from different harnesses, effort levels and task subsets. 1 of them match, which usually means one side copied the other. Every benchmark.
| Model | Lab says | Board says | Gap |
|---|---|---|---|
| GPT-5.6 Luna | 78.6% FrontierMath Tier 1-3 (v2) | 82.1% Leaderboard, max; task version 2.0.0, Epoch | −3.5 pts |
| GPT-5.6 Terra | 84.9% FrontierMath Tier 1-3 (v2) | 86% Leaderboard, max; task version 2.0.0, Epoch | −1.1 pts |
| GPT-5.6 Sol | 89% FrontierMath Tier 1-3 (v2) | 89.1% Leaderboard, max; task version 2.0.0, Epoch | Same |
Versions
We switch the top row to each new version when it comes out. Open it for one row per version. An old version stays in play while people still test it, so whoever first takes it past 85% gets credit for closing it out.
