Abstract

Pairing AGIQA-3K rows by prompt reveals small average quality differences but substantial prompt-to-prompt variation among four recorded Stable Diffusion conditions. Relative to sd1.5_normal, mean quality differences are -0.088 for highcorr, -0.145 for lowcorr, and -0.070 for lowstep. Each contrast contains 300 prompt pairs. The study describes released judgments and does not rerun generation settings. It illustrates why an average condition difference should be accompanied by its pairing structure and the distribution of individual prompt contrasts.
