A deep dive into the WAI Illustrious model for Stable Diffusion reveals surprising insights into its tag vocabulary and usage. The analysis found that common descriptive terms like "silver hair" and "dramatic lighting" are not directly indexed in Danbooru, while related terms like "grey hair" and "backlighting" are. Furthermore, quality-related labels such as "masterpiece" and "amazing quality" are training-time labels, not Danbooru tags, meaning their prevalence doesn't correlate with image quality. The research also highlights that only a small fraction of artist tags have significant post counts, suggesting a need for more strategic artist selection in prompts. AI
