LongJudgeBench (Rubric): leaderboard

LongJudgeBench (2026) measures how often an LLM judge agrees with human judgments on long-form outputs averaging over 9,000 tokens: deep research reports, scientific surveys, creative writing, long reasoning chains and systematic reviews. This board is judge accuracy in percent averaged over all six datasets, the judge working given task-specific rubrics; higher is better.

Metric: Judge accuracy (%) averaged over the six datasets (DeepResearch Bench, RealDeepResearch, SurGE structure and content, WritingPreferenceBench, VerifyBench, MA): agreement of the LLM judge's pairwise preferences (from pointwise scores, pairwise choices or listwise ranks) or correctness labels with the human reference judgments, averaged within query groups, temperature 0, judging with task-specific rubrics; higher is better.
