An illustrator, Hollie Mengert, discovered that her work had been used to train an AI model without her permission, allowing others to generate images in her style. The model was created using Stable Diffusion and DreamBooth, a technique for introducing new subjects to a pretrained text-to-image diffusion model. Mengert expressed discomfort with her name being associated with the model and felt that it was invasive. The incident raises questions about the ethics of using artists' work to train AI models without their consent.
