OpenProblemBench: Benchmarking AI on Open Problems in the Foundational Theoretical Sciences

OpenProblemBench is a new benchmark that presents 82 unresolved problems from mathematics and theoretical physics, each with detailed context, assumptions, and prior progress. The benchmark evaluates AI submissions on correctness, completeness, and progress using four independent evaluator models, without providing reference solutions. GPT‑6‑Astra achieved the highest mean judged solve rate of 14.0%, outperforming other evaluated models, and the study links stronger outcomes to improved problem representation, general reasoning, and proof steps.

Measuring Progress in Reasoning Toward Mathematical Discovery with Automatic Verification

The paper introduces HorizonMath, a benchmark of 113 largely unsolved mathematical problems across eight domains, paired with an open-source framework for automated verification. It focuses on the generator‑verifier gap, targeting problems that are hard to discover but easy to verify computationally, thereby avoiding costly formal proof verification or manual review. Using this framework, the authors found six novel solutions—three each from GPT‑5.4 Pro and GPT‑5.6 Sol—demonstrating that current models can contribute to mathematical research, while most state‑of‑the‑art models score below 10%.

OpenFrontiers: A Collection of Open Research Problems and a Benchmark for Scientific Rediscovery

OpenFrontiers is a cross‑disciplinary resource that compiles 12,151 open research problems and a benchmark of 200 recently resolved mathematics problems, including 110 solved in 2026 and 90 still open. Each benchmark problem is formally stated in Lean 4, verified by automated probes, and reviewed independently. The evaluation protocol tests LLM agents under closed‑book, frozen‑retrieval, and live‑web conditions, revealing that closed‑book rediscovery is rare while live‑web success largely reflects retrieval of published solutions.

ASI-Bench: At the Dawn of Artificial Superintelligence

ASI‑Bench is a new benchmark that evaluates AI systems on their ability to conduct innovative exploration and autonomous scientific research across 11 domains, using 60 project‑level tasks. It progressively removes human methodological guidance to test whether AI can independently select methods, execute research, and produce verifiable results. Results from 18 state‑of‑the‑art agent–model configurations show a sharp performance drop when guidance is reduced, indicating current systems still rely heavily on human input.

Beyond Selected Breakthroughs: Evaluating Language Models on Randomly Sampled Mathematical Conjectures

The paper introduces OpenConjecture, a dataset of mathematical conjectures from arXiv papers since February 2026, and evaluates frontier GPT models on 200 randomly sampled conjectures. The models generate candidate solutions for about 60% of the conjectures, with counterexamples occurring roughly 1.3 times more often than proofs. The study examines solution novelty, citation practices, and fidelity to the original statements, finding that some solutions deviate from authors’ intent and that many proofs closely follow existing results, though some exhibit moderate novelty.

ReuF2F: Benchmarking Coding Agents on Formalized Undergraduate Research Problems

ReuF2F is a Lean 4 benchmark comprising 244 formalized open problems sourced from Research Experiences for Undergraduates (REU). It aims to evaluate coding agents on less prominent, entry‑level research problems across diverse mathematical subfields, using a Docker‑based Lean project setup and a unified harness called Leanimum‑agent. The study finds that even the best model solves only about 40 % of the problems, indicating significant room for improvement.

Ramanujan Challenge Results: AI-Assisted Evaluation Pipeline for Multi-Format Proofs

The paper reports on the Ramanujan Challenge, a benchmark of research‑level number theory problems, and evaluates submissions from AI models, CAS, and formal tools. It highlights that some correct solutions differ conceptually from official ones and even proves a published open conjecture. The authors introduce an AI‑assisted evaluation pipeline that significantly lowers false positives in natural language proofs and improves accuracy for supporting code, offering a scalable method for assessing high‑level mathematical work.
