xAI is suing Minnesota Attorney General Keith Ellison over a law passed back in May that broadly targets "nudification" apps, claiming that the statute's punitive provisions leave the company with "no practical choice but to restrict Grok Imagine's image-editing features in various ways." The law, the company argues, violates the First Amendment. Back in January, Grok flooded the internet with millions of sexually explicit deepfakes, including images of minors. In another era, a content moderation disaster of this magnitude would have had the CEO flipping the kill switch on the product within...

In an interview with our friend Joanna Stern on her YouTube channel, OpenAI president Greg Brockman said the company is working on a "family of devices" for interacting with its AI models. However, Brockman didn't confirm reports that one of those devices is a smart speaker OpenAI's rumored to be launching in 2027, or earlier rumors that the device might be a wearable like the Humane AI pin. He didn't give a release date, either, only saying that "you can expect them soon." When asked about whether Apple's lawsuit against OpenAI could impact the devices it's working on with former Apple desig...
