ThumbnailTruth tests whether YouTube thumbnails accurately preview videos by asking language models to compare each image with subtitles and a generated scene summary. On a curated, class-balanced dataset, Claude 3.5 Sonnet reached 93.8% accuracy, while GPT-4o Mini reached 84.8% at its best prompt settings. The dataset is not representative of YouTube, and the study does not establish production performance.
