Disney has accused Google of copyright infringement on a “massive scale,” alleging that the tech giant is training its AI tools on protected materials as well as allowing those tools to generate infringing images and videos. Variety reports that Disney attorneys sent a cease-and-desist letter to Google on Wednesday.

“Google is infringing Disney’s copyrights on a massive scale, by copying a large corpus of Disney’s copyrighted works without authorization to train and develop generative artificial intelligence (‘AI’) models and services, and by using AI models and services to commercially exploit and distribute copies of its protected works to consumers in violation of Disney’s copyrights,” reads the letter, which Variety reviewed.

The letter includes examples of images from several Disney properties including Deadpool, Moana, Star Wars and others, reproduced by Google’s AI tools. Disney is demanding that Google implement guardrails within all its AI products to prevent further infringement. The media giant sent a similar letter to Character.AI in September, and is currently suing Hailuo and Midjourney over alleged copyright infringement.

Copyright enforcement has become more challenging in the face of AI-created imagery, and companies are increasingly taking an “if you can’t beat them, join them” approach. Today Disney announced a deal with OpenAI to license its characters for use in Sora, OpenAI’s video generator. The deal will see Disney invest $1 billion in OpenAI (a paltry sum by some standards), with the option to purchase additional equity at a later date.
