SWE-PRBench (Config A): leaderboard

Metric: Composite review score (0-1, scaled to 0-100): per pull request, 0.40 recall + 0.25 precision + 0.15 alignment + 0.10 actionability + 0.05 efficiency minus hallucination, redundancy and excess-plausible penalties, clamped to 0-1 and averaged with weights log(human comments + 1), on a stratified 100-PR sample of SWE-PRBench (40 direct, 40 contextual and 20 latent-difficulty pull requests from active open-source repositories), each model asked at temperature 0 for 4 to 6 line-anchored review comments as JSON, a GPT-5.2 judge matching them to the human reviewers' comments (confirmed, plausible or fabricated), with the diff-only context (task focus, key-change summary, diff and minimal metadata; about 2,000 tokens); higher is better. Source: arxiv.org. Saturation forecast: Around 2029. 8 models tracked.
