What it measures, and how

How this evidence is used

Officially scored; the two writing leaderboards together account for 6%, with no added weight by question or model count.

Limits and data attribution

Mainly English writing, relying on a model judge; the same judge and related tasks share a budget and do not represent Chinese prose quality.
