Reported in recent model launches
These model reports include this benchmark. Their harnesses, task subsets, scoring policies, and resource budgets can differ; follow each report’s evaluation notes before joining the numbers.
What it measures
Olympiad-related mathematics is evaluated through answer-oriented scoring in frontier model reports.
How to read the result
Read the score as the published answer-checking contract. Ask whether a proof-sensitive companion evaluation supports the same conclusion.
Limits and comparison traps
An answer benchmark is not an official IMO medal result or formal proof certification. Reported task splits and inference budgets must remain visible.
Benchmark reference notes
International Mathematical Olympiad-style problems reformulated with verifiable short/numerical answers.
Where this fits in an evaluation suite
Final-answer accuracy, proof credit, and expert-reviewed research progress are distinct signals. A proof-aware evaluation should retain partial work and audit strong claims.
Start with a capability hypothesis, then choose a second test with a different failure mode. Keep the checkpoint, reasoning effort, agent tools, sampling policy, and scoring procedure fixed when measuring a training intervention. Record failures and missing outputs in the denominator.
A reproducible comparison
Pin the benchmark release, task split, model configuration, tools, sampling budget, and evaluation harness described by the primary source.
Publish the exact run configuration, item coverage, score units, and available uncertainty. If a source supplies only an aggregate or a single run, preserve that limit. A new model name or a rounded score alone does not establish a capability improvement.
