In response to controversy over image synthesis models learning from artists' images scraped from the Internet without consent—and potentially replicating their artistic styles—a group of artists has released a new website that allows anyone to see if their artwork has been used to train AI.
The website "Have I Been Trained?" taps into the LAION-5B training data used to train Stable Diffusion and Google's Imagen AI models, among others.
Not everything is open source on the Internet, and even open source licenses may require attribution, non-commercial use, or possibly prohibit modification. It is the artists freedom of choice to decide how their work is used or reused. Whether all of that is still considered open source, is a different matter that Richard Stallman will no doubt weigh in on.
One thing I hope though, is that we don't go through lots of "false copyright take down claims" as there is nothing worse than automated take downs, and you have to be blocked and resubmit your genuine work. I suppose though it can never be a perfect world (we have humans in the world after all).
