Researchers have introduced a new metric called pairwise reference alignment to evaluate language models. This metric quantifies how well a model's ranking of responses aligns with a predefined reference distribution of preferences. The formulation provides a conceptual and statistical framework for this alignment, distinguishing it from other scoring methods and offering estimators with concentration bounds. Initial experiments on Qwen2.5 models and RewardBench suggest the alignment metric increases with model size and instruction tuning. AI
