They have bought the licenses in good faith, but I wouldn't be surprised if there were tons of images on their platform that the original seller had no right to sell to Getty.

If the copyright lawsuits do end up ruling against image AI statups, Getty may face problems when inevitably someone demands Getty takes down the images they had no right to buy and use, and retrain the AI to exclude those images from generated works as well.

However, until something like that happens, Getty has every right to generate images, of course.

Sometimes. Often, they hold a license for something that's also in the public domain.
