Large language models (LLMs) are used worldwide, yet disproportionately reflect Western values, limiting their ability to represent diverse value systems. We introduce PLURAL, a large-scale, value-focused preference dataset grounded in the Integrated Values Survey (IVS), a nationally representative survey spanning 92 countries. Using a two-stage generation pipeline, we transform survey responses into synthetic preference triplets that preserve normative value signals while producing realistic scenarios. We release an initial version of PLURAL containing ~500,000 preference triplets representing people in 20 diverse countries. We evaluate PLURAL in three ways: (i) dataset-level validation showing that it preserves both cross-country value differences and within-country diversity from the original survey; (ii) automated evaluation showing that training on PLURAL improves alignment with target countries' cultural profiles, reducing mean absolute error by up to 27.7% relative to strong baselines; and (iii) blind human evaluation with 176 evaluators in India, Brazil, and Japan, who judge PLURAL-aligned responses as more representative of their national values. Together, these results show that PLURAL contains learnable signal for value steering, offering a scalable resource for pluralistic alignment.

Text-to-image models produce graphic design at production scale, but their supervision comes from photo-style preference data with a single overall verdict per comparison. Designers evaluate along several distinct axes, including typography, visual hierarchy, color harmony, layout, and brief fidelity, and a single label collapses them. We release TASTE (Typography, Aesthetics, Spatial, Tone, Etc.): ten professional designers ranked outputs from four current text-to-image models on nine criteria across two disjoint cohorts, yielding 1,600 ratings per criterion plus per-image hallucination flags on the holistic-preference cohorts. We pair the dataset with three contributions. First, a criterion-agnostic signal test framework, using Kendall's tau, majority probability, and Condorcet cycles against exact iid-uniform nulls at p = 4 and R = 5, places designer agreement on graphic design between food and movie preferences and photo-style image quality, with every TASTE criterion rejecting the random-rater null. Second, no pre-trained system in our benchmark, including six open-weight VLM judges from 3B to 33B parameters and three dedicated T2I scorers, HPSv2.1, PickScore-v1, and LAION-Aesthetic-V2, exceeds 0.55 macro agreement with the 5-designer majority; VLM judges trade off position bias against content sensitivity, so scaling moves along this frontier without improving accuracy. Third, a small pairwise-difference head trained on TASTE reaches 0.611, closing roughly half the gap to the 0.741 single-rater ceiling.
