JUANA SUMMERS, HOST:Minnesota has banned AI that lets users depict real people as naked in fake photos or videos without their permission. The law takes effect this weekend, but is facing a challenge from Elon Musk's company, claiming it infringes on free speech. FERGUSON: It turned out the Minnesota man used photos of dozens of acquaintances to produce AI deepfake nude images without their consent. But this week, xAI sued, saying the law violates the rights of the company and Minnesotans who use its AI model, Grok. On X, he said using AI to create nude images of people against their will is appalling.
