Study Finds Prompt Rewriting Adds Cultural Bias in Text-to-Image Models
A new arXiv paper argues that commercial text-to-image services quietly rewrite user prompts before image generation, a step people usually cannot see or turn off. Prior cultural-bias audits, the authors note, only look at finished images and treat the whole process as one pipeline, which hides where the bias enters. The work calls for examining this hidden revision stage separately.
