A multilingual mathematical reasoning benchmark that tests whether math performance transfers across languages rather than only in English.
BenchLM is tracking PolyMath in the local dataset, but exact-source verification records for these rows are still being attached. To avoid a blank benchmark page, BenchLM shows the current tracked rows below as a display-only reference table.
These tracked rows are useful for inspection and spot-checking, but until exact-source attachments are completed they should not be treated as fully verified public benchmark rows.
BenchLM mirrors the published tracked score view for PolyMath. Claude Opus 4.5 leads the public snapshot at 79.0% , followed by Qwen3.6 Plus (77.4%) and Qwen3.5 397B (73.3%). BenchLM does not use these results to rank models overall.

The published PolyMath snapshot is tightly clustered at the top: Claude Opus 4.5 sits at 79.0%, while the third row is only 5.7 points behind. The broader top-10 spread is 35.9 points, so the benchmark still separates strong models even when the leaders cluster.
5 models have been evaluated on PolyMath. The benchmark falls in the Multilingual category. This category carries a 7% weight in BenchLM.ai's overall scoring system. PolyMath is currently displayed for reference but excluded from the scoring formula, so it does not directly affect overall rankings.

Cross-lingual mathematical reasoning
Difficulty
Advanced multilingual reasoning
PolyMath isolates cross-lingual math transfer rather than general chat quality. It is useful for spotting models that keep surface fluency in other languages but lose structured reasoning quality.
