What's happened: Artists are now able to opt out of the next version of one of the world's most popular text-to-image AI generators, Stable Diffusion, the company behind it announced. Creators can search a website called HaveIBeenTrained for their works in the data set that was used to train Stable Diffusion, and select which works they want to exclude from the training data. Why it's important: The decision comes amid a heated public debate between artists and tech companies over how text-to-image AI models should be trained. The artist couple who created the website hope that the opt-out service will temporarily compensate for the absence of legislation governing the sector. For the past five years or so, barely a week has gone by without a study, comment, or press release about the potential benefits of psychedelic drugs.
