m-ArenaHard v2.1
Models answer the 498 Arena-Hard v2.0 prompts translated into 67 languages, with code and data kept intact. A GPT-4.1 judge rates answers with a rubric in the Tiny Aya report.
Expands v2.0 from 23 to 67 languages and repairs code-heavy prompts and corrupted English rows, so it is not comparable with v2.0.
