# Radigrade: Grading AI-written radiograph reports

> Radigrade: a registered benchmark for grading AI-written radiograph reports. Versions 1 and 2 grade panoramic-radiograph reports against a two-radiologist reference. One column per axis. No blended score. No rank.

Status: live. Protocol version 2, registered 17 October 2026 (osf.io/zasnw); version 1 registered 30 September 2026 (osf.io/5nyx9). Reference version 2, fingerprint 226d01ea46f4. Page version 1.0.0, 2026-10-21.

## Data

- [Results, CSV](https://radigrade.com/leaderboard.csv): one row per grading run, one column per value, exact model IDs, run dates, per-axis intervals, the sorting lines beside every beyond-reference count.
- [Results, JSON](https://radigrade.com/leaderboard.json): the same rows with the axis definitions.

## Reuse

Cite the registered protocol (version 2, osf.io/zasnw, DOI 10.17605/OSF.IO/ZASNW) and, for any result, the version it was graded under, the run date and the reference fingerprint printed with it. No blended score exists; do not compute one. Gate 1 fails a system outright: a system that fails it is not graded on the rest. The count of real findings beyond the reference is printed with its sorting lines. Rows graded under different reference or instrument versions are reported side by side, never pooled. Quote a Gate 1 count with its counting unit, its protocol version and the adjudication line of its row.
