Getty Images is accusing Stability AI of copying 12 million images from its database without permission or compensation. In January 2023, Getty Images launched a lawsuit against Stability AI, the company behind a popular text-to-image generator, Stable Diffusion. Now, Getty CEO Craig Peters says that though he believes Getty has a "very strong" case against Stability AI, fighting the AI company in court has been costly. "We're spending millions and millions of dollars in one court case," Peters told CNBC on Wednesday, calling the effort "extraordinarily expensive." Stability AI argues that its AI model was trained on Getty Images through "temporary copying," which is momentarily copying the picture to train the dataset.
