FACTS Grounding v2 leaderboard

FACTS Grounding v2 is an external benchmark published by FACTS Grounding v2 methodology. FACTS Grounding v2 checks whether long-form answers remain supported by supplied documents. Its revised judge ensemble and public/private results remain separate from version 1. Its evaluation set is described by the source as 1,719 document-grounded examples: 860 public and 859 held out.

Each model's result is published by FACTS Grounding v2 methodology as long-form document-grounded answers. ModelScale prints that value to 1 decimal place, exactly as published, and never converts or rescales it. This page ranks the 0 models that carry a published value, highest value first; a model the source never scored is left out rather than ranked at zero. The source does not state whether a higher value is the better result, so neither does this page.
