Artists sue the image generators

On 13 January 2023 Sarah Andersen, Kelly McKernan and Karla Ortiz filed a class action against Stability AI, Midjourney and DeviantArt, case 3:23-cv-00201. The complaint says Stability paid LAION to assemble LAION-5B, a set of 5.85 billion captioned images, trained Stable Diffusion on it, and that the images the model produces are derivative works of the art that entered the set without permission.

Why it matters

This is the first suit in which artists as a class stood against an image generator. It moved the dispute from code to drawing and raised a question the Copilot suit had not: whether the model's output is itself a derivative work, and not only the way the model was trained.

Four defendants are named: Stability AI Ltd. of the United Kingdom, Stability AI, Inc. of Delaware, Midjourney, Inc. and DeviantArt, Inc. Paragraph 104 names LAION-5B and its 5.85 billion training images; paragraph 57 says over five billion images were copied. Paragraph 60 records the October 2022 raise of 100 million dollars led by Coatue and Lightspeed at a Stability valuation of about one billion. What the record does not claim. The suit also challenges the consumer services, DeviantArt's DreamUp and Midjourney, but nothing is said here about whether those claims survived. Later changes of parties, including the addition of Runway AI in November 2023, are outside this record.
