Disney and Universal sued Midjourney, alleging that the artificial-intelligence company’s image-generating service produces unauthorized copies of the studios’ copyrighted works.

Disney and NBCU filed a federal lawsuit Tuesday against Midjourney, a generative AI start-up, alleging copyright infringement. The companies alleged that Midjourney’s own website “displays hundreds, if not thousands, of images generated by its Image Service at the request of its subscribers that infringe Plaintiffs’ Copyrighted Works.”
