Rather than drawing from a fixed, static problem set, ArXivMath curates final-answer questions from mathematics papers newly posted to arXiv each month — questions are selected and adapted to be both nontrivial (not solvable by pattern-matching) and automatically gradable (verifiable final answers). A high ArXivMath score is a stronger signal of genuine mathematical reasoning than scores on older, static benchmarks, precisely because the questions can't have been seen during pretraining. MathArena reports scores as an average over multiple independent runs (typically four) per problem to reduce variance from sampling. ## Benchmark Specifications | Field | Value | |---|---| | Task category | Math | | Metric | Automatically graded final-answer accuracy (avg. of 4 runs) | | Number of tasks | Rolling monthly collection; no fixed aggregate count published | | Saturation | Low | | Created by | Dekoninck, Jovanović, Gehrunger, Rögnvaldsson, Petrov, Sun, Vechev (MathArena / ETH SRI) | | Source paper | [Dekoninck et al. 2026](https://arxiv.org/abs/2605.00674) | | GitHub | [eth-sri/matharena](https://github.com/eth-sri/matharena) | | Leaderboard | [matharena.ai](https://matharena.ai/) | ## How ArXivMath Is Scored Each question has an automatically-checkable final answer. Models are typically run four times per problem, and the reported score is the average accuracy across those runs — reducing the chance a single lucky (or unlucky) sample distorts the result. ## State-of-the-Art Results | Rank | Model | Score | Source | Date | |---|---|---|---|---| | 1 | [Hy4 Preview](/models/hungyuan/hy4-preview) | 66.6% | [Tencent Hunyuan model card](https://huggingface.co/tencent/Hy4-preview) | 2026-08 | *Scores sourced from published technical reports and model cards.

What is ArXivMath?

ArXivMath is a MathArena track that derives final-answer math questions from newly published arXiv papers each month, designed to resist training-data contamination.

What does a good ArXivMath score look like?

As of August 2026, frontier models score in the 43–80% range; scores above 66% represent strong performance on genuinely novel math reasoning.

Who created ArXivMath?

ArXivMath is part of MathArena, created by Dekoninck, Jovanović, Gehrunger, Rögnvaldsson, Petrov, Sun, and Vechev at ETH Zurich's SRI lab and INSAIT.
