Vision-Language Models Generate More Homogeneous Stories for Phenotypically Black Individuals

Messi H. J. Lee, Soyeon Jeon

Vision-Language Models (VLMs) extend Large Language Models' capabilities by integrating image processing, but concerns persist about their potential to reproduce and amplify human…

Visual Cues of Gender and Race are Associated with Stereotyping in Vision-Language Models

Messi H. J. Lee, Soyeon Jeon, Jacob M. Montgomery +1

Current research on bias in Vision Language Models (VLMs) has important limitations: it is focused exclusively on trait associations while ignoring other forms of stereotyping, it…
