RubricBench - Code: leaderboard

Metric: Preference accuracy (%) on the code pairs on RubricBench's 1,147 preference pairs (instruction following, STEM, code, safety and chat pairs re-curated from HelpSteer3, PPE and RewardBench2 and filtered so that surface cues such as length, formatting or tone favour the rejected response); the reward model or LLM judge picks the preferred response directly, with no rubric; higher is better. Source: arxiv.org. Saturation forecast: Around 2031. 10 models tracked.
