XDecideBench is a benchmark of typed decisions across languages. A typed decision is a probability distribution over a declared, finite output space: one of k options, yes/no, or an ordinal level. The benchmark scores the submitted distributions, not generated text, on nine suites in 122 languages, and checks whether confidence policies fitted in English hold in other languages.
