No result for MMLU is on file yet. We list a result only when we can trace it to a published source, and record the settings exactly as that source states them. HARBAN has not yet published internal evaluations of this benchmark.

Definitions, health labels and caveats are summarised in our own words from the linked sources. Scores are reproduced exactly as each source published them; see the methodology for how we record and group them.
