The companies asked a San Francisco federal court to dismiss the artists' proposed class action lawsuit, arguing that the AI-created images are not similar to the artists' work and that the lawsuit did not note specific images that were allegedly misused.
Sarah Andersen, Kelly McKernan and Karla Ortiz sued the companies in January. The artists alleged that the unauthorized copying of their works to train the systems and the creation of AI-generated images in their styles violated their rights. DeviantArt, an online artist community with a service that allows users to create images through Stability's Stable Diffusion system, echoed those arguments and also said it was not liable for the AI companies' alleged misconduct.
