Benchmark definition

MGSM

ActiveEstablishedCommon useMGSM

A multilingual grade-school math benchmark created by manually translating 250 GSM8K problems into 10 languages.

Applicability does not mean evaluated; benchmark result/model score data is outside this UI contract.

Counted over 58 models in the default lifecycle scope (active, preview, experimental).

Every required condition, for the whole benchmark, is recorded as supported. Each line is one recorded condition and why it counts.
