MathArena's August 2026 research-mathematics release: 57 questions, native model harnesses, Python and SageMath without internet, and Gemini 3.8 Flash answer-equivalence grading. New construction emphasizes resolved conjectures; this tool-enabled protocol is distinct from earlier monthly evaluations. Time and cost limits were introduced partway through the published runs.
