Elon Musk‘s journey from AI alarmist to AI evangelist has played out noisily on X/Twitter, but now the mercurial billionaire is touting the latest frontier for the technology: A rapid video generation tool that is being used to create deepfake nudes of celebrities. Grok Imagine was rolled out this week to Apple users and has gone “hyperviral,” with more than 34M images generated in the space of 48 hours, according to Musk. 

Available through a $30 SuperGrok subscription, users type a text prompt, creating a still image almost instantly. These images can then be turned into a short video using four presets: “Custom,” “Normal,” “Fun,” and “Spicy.” Of the four, “Spicy” mode quickly garnered attention, turning seemingly innocuous image prompts into lewd snippets.
