Legal disclaimer Most image-generating AI models were trained using works that are protected by copyright. In some cases, such assets and models can produce images that contain major copyrightable elements of those copyrighted training images, making these outputs derivative works. Accordingly, there is a risk that AI-generated art uploaded on Commons may violate the rights of the authors of the original works. See Commons:AI-generated media for additional details.
