The aim of this study was to compare patient and physician evaluations of ChatGPT-5 and DeepSeek V3.1 responses to questions on Hashimoto's thyroiditis.  METHODS: In a cross-sectional, double-blind, within-participant study, twenty standardized, endocrinologist-developed questions across six domains were submitted to both models in October 2025. Seventeen adults with confirmed Hashimoto's thyroiditis (mean age 47.6\u00b113.5 years; 88.2% female; 64.7% bachelor's degree or higher) rated each blinded response for clarity and satisfaction on 10-point Likert scales and selected a preferred response. Two endocrinologists also rated responses blindly; with only two physicians, their ratings were summarized descriptively. Paired t-tests with Holm correction compared ratings, and preference was analyzed with mixed-effects logistic regression.  RESULTS: Patients rated ChatGPT-5 higher than DeepSeek V3.1 for clarity (9.15\u00b10.70 vs. 8.41\u00b11.14; Holm-adjusted p=0.005; Cohen's d_z=0.87) and satisfaction (8.93\u00b10.94 vs. 8.19\u00b11.37; Holm-adjusted p=0.005; d_z=0.85), and preferred ChatGPT-5 in 68.8% of selections (odds ratio 2.20; 95%CI 1.75\u20132.77; p&lt;0.001). In exploratory analyses, this advantage was concentrated among higher-education participants and was undetectable in the small lower-education subgroup (n=6). Owing to the small physician sample (n=2) and low inter-rater agreement (\u03ba=0.12; accuracy intraclass correlation coefficient=0.48), physician accuracy ratings (5.90 and 5.70\/10) are exploratory and do not support a robust patient\u2013physician comparison.  CONCLUSION: Patients preferred ChatGPT-5 for clarity and satisfaction, though this advantage may not extend to lower-health-literacy populations; high patient satisfaction should not be taken as a proxy for clinical accuracy. Physician-supervised deployment and language-specific validation are recommended for responsible integration of artificial intelligence into patient education.<\/jats:p>","DOI":"10.1590\/1806-9282.20260144","type":"journal-article","created":{"date-parts":[[2026,8,24]],"date-time":"2026-08-24T11:09:19Z","timestamp":1787569759000},"source":"Crossref","is-referenced-by-count":0,"title":["Patient-perceived
