# JudgeBench leaderboard

external benchmark

> Every figure below is reproduced as its upstream source published it: nothing is modelled, estimated, interpolated or converted. `Unavailable` means no source published the value — it is never a zero. Each value carries its evidence state and the date it was observed.

Every model the catalog carries a published JudgeBench value for, ranked by that value.

## Benchmark record

| Field | Value |
| --- | --- |
| Category | external |
| Measure | Decision classification |
| Tasks | Choosing the better of two model responses |
| Difficulty | Depends on the evaluated split and label mapping |
| Published by | [JudgeBench: A Benchmark for Evaluating LLM-Based Judges](https://github.com/ScalerLab/JudgeBench) |

JudgeBench evaluates whether a judge can identify the better response in pairs with objective correctness labels. It tests judgment on challenging questions rather than agreement with writing style preferences.

## JudgeBench ranking

No model in the catalog has a published JudgeBench score. The benchmark is defined by JudgeBench: A Benchmark for Evaluating LLM-Based Judges, but the catalog carries no value for it yet. An absent value is shown as absent here rather than as a zero.

Rows are ordered by the value the source published, highest first. The source does not state whether a higher value is the better result, so this document does not either: for a benchmark that measures a rate of failure, read the table from the bottom.
