SemanticAlign-Bench - Experimental Protocol: leaderboard
The experimental protocol claims of SemanticAlign-Bench (SA-Bench; Beihang University, Shanghai Jiao Tong University and Peking University, 2026): whether an agent-written reproduction repository implements the datasets, splits and training and evaluation procedures of the paper, scored by GPT-5.5 on a five-level rubric from 0 to 1. Higher is better.
Metric: Semantic alignment score (0-1; experimental-protocol claims (datasets, splits, training and evaluation procedure); 30 ICLR, ICML and NeurIPS 2025 papers with 1,491 atomic implementation claims; the agent reads the paper and writes a reproduction repository, and GPT-5.5 scores each claim against the code on a five-level rubric (0, 0.25, 0.5, 0.75, 1) without executing it; mean over the 30 paper-level scores). Source: arxiv.org. Saturation forecast: Around May 2027. 12 models tracked.
