Nvidia Corp (NVDA.O) unveiled its own service, known as "Picasso," that uses AI to generate images, videos and 3D applications from text descriptions. Nvidia trained the technology on images licensed from Getty Images, Shutterstock Inc (SSTK.N), and Adobe, and plans to pay royalties. Image-generation technology is "trained" on billions of images, but whether that use is legally permitted is not always clear. Because the AI has been trained on Adobe Stock images, openly licensed content and older content where copyright has expired, the resulting creations are safe for commercial use, it said. "We're very interested in making this creator friendly," Ely Greenfield, chief technology officer for digital media at Adobe, told Reuters.
