Swipe the table sideways for more columns.

Ranks follow the score as shown, so equal numbers share a rank. ≈ marks results whose 95% range overlaps the leader's: they cannot be told apart from it. Results as published by Arena (formerly LMArena); we do not re-run them.

What it measures

Human preference combined with labels of whether each answer's checkable claims were true (factuality weighted 25% by default).

What it does not measure

Not an error rate: claims that cannot be checked on the web are skipped, and preference still carries most of the weight.
