Thanks to his distinctive style, Rutkowski is now one of the most commonly used prompts in the new open-source AI art generator Stable Diffusion, which was launched late last month--far more popular than some of the world's most famous artists, like Picasso. His name has been used as a prompt around 93,000 times. He thinks it could threaten his livelihood--and he was never given the choice of whether to opt in or out of having his work used this way. The story is yet another example of AI developers rushing to roll out something cool without thinking about the humans who will be affected by it. Stable Diffusion is free for anyone to use, providing a great resource for AI developers who want to use a powerful model to build products.
