Disney and Universal Studios have filed a lawsuit against artificial intelligence company Midjourney, alleging copyright violations of their intellectual property.

The movie studios claim Midjourney, a popular subscriber-based interface that generates AI images from text prompts, has trained its AI models on their intellectual property and creates images featuring their famous characters.

For example, according to the lawsuit, if a Midjourney subscriber submits a simple text prompt requesting an image of the character Darth Vader in a particular setting or doing a particular action, Midjourney generates a high-quality, downloadable image featuring Disney’s copyrighted Darth Vader character.
