University of Chicago “Nightshade” poisons AI to protect artists

Share post:

Researchers at the University of Chicago have developed a groundbreaking tool called Nightshade, which has rapidly gained popularity with an impressive 250,000 downloads in just five days. Designed primarily for artists, Nightshade aims to disrupt AI models that train on artworks without consent, addressing a growing concern in the art community.

Nightshade operates by subtly altering images at the pixel level, causing them to be interpreted as entirely different content by machine learning algorithms. This process, known as “poisoning,” can lead to AI models generating inaccurate imagery based on user prompts. The tool’s swift uptake is a clear indication of the strong desire among artists to safeguard their creations from unauthorized AI training. Its global popularity underscores the widespread apprehension over the use of unlicensed data in training AI models.

The strategy behind Nightshade is to increase the cost of training on unlicensed data, thereby making it more appealing for AI developers to license images directly from creators. This approach offers a novel way to protect artistic works in the digital age.

Building on the success of Nightshade, the University of Chicago team, also known for their earlier tool Glaze, plans to release a combined version of both tools. Glaze, which has been downloaded 2.2 million times since April 2023, is designed to shield an artist’s unique style from being replicated by AI models. The integrated tool will provide artists with both defensive and offensive measures against the unauthorized use of their work in AI model training.

Project leader Ben Zhao expressed his surprise at the enthusiastic reception of Nightshade and is considering releasing an open-source version in the future. The team’s efforts underscore the ongoing conflict between AI development and artists’ rights, highlighting the necessity for ethical practices in AI model training.
