arXiv:2605.30758v1 Announce Type: cross Abstract: Pairwise preference data is widely used in language-model evaluation and alignment, often for model ranking, reward modeling, or preference optimization. This note formulates a more basic measurement question: given a reference distribution of pairwise preferences, what model-level quantity is estimated when we test whether a model ranks preferred responses above rejected responses? We define pairwise reference alignment as an ordinal observable induced by a model scoring function. Given a reference pair distribution $P_{\mathrm{pair}}$ over tr
The rapid deployment and scaling of large language models necessitate more robust and quantifiable methods for evaluating their alignment with human preferences.
A more precise and 'model-level' understanding of how AI systems align with human reference data is crucial for developing safer, more reliable, and ultimately more autonomous AI.
The focus shifts from general evaluations to a more fundamental measurement question, defining 'pairwise reference alignment' as a quantifiable model-level ordinal observable.
