Where Glaze protects one artist's style, Nightshade is meant to make scraping unlicensed work actively costly — poisoned images that push a model towards wrong associations when they end up in a training set.

Same research group, same local-only design. It is a deliberate escalation and its authors describe it as such.

Worth knowing before you start

Effectiveness depends on volume A handful of poisoned images in a large dataset does little.
Slow Processing is heavy, particularly without a GPU.
