Fighting against data used to train AI models has become more poisonous.

A new tool called Nightshade allows users to attach it to their creative work, and it will corrupt — or poison — training data using that art. Eventually, it can ruin future models of AI art platforms like DALL-E, Stable Diffusion, and Midjourney, removing its ability to create images.

The MIT Technology Review reported that Ben Zhao, a professor at the University of Chicago and one of the…
