Amid a scandal over nonconsensual sexual images, Musk says his AI chatbot is a force for "truth and beauty." Get your news from a source that's not owned and controlled by oligarchs. In much of the world, Grok and its parent company both appear to be in serious trouble. After Grok, X's AI chatbot, has been used to generate sexualized and violent images of women and children, the social media company has faced a wave of backlash and censure, with new nationwide bans on accessing Grok in place and other consequences on the way. On Monday, the EU threatened to fine X under its broad Digital Services Act if it didn't act "quickly" to fix Grok, in the words of one regulator.

The United Kingdom plans to bring into force a law that criminalizes the creation of non-consensual sexualized images, including through Grok, the chatbot within Elon Musk's X application, following the app's deepfake scandal of the last few weeks. "This means individuals are committing a criminal offence if they create--or seek to create--such content--including on X--and anyone who does this should expect to face the full extent of the law," Technology Secretary Liz Kendal announced in the House of Commons Monday, adding that the government would work to also make it illegal for companies to supply the tools designed to create these nonconsensual images. The move came just hours after the Office of Communications (Ofcom)--the country's independent regulator for the communications industry--announced that it will be investigating X and the thousands of pornographic images generated by Grok that flooded the app, including sexualized images of what appear to be minors.

Animal trials helped to restore order when the unspeakable happened. In 1457, a sow and her piglets were put on trial for the murder of a child in the village of Savigny in Burgundy, France. The sow was ultimately found guilty and her piglets were acquitted. Breakthroughs, discoveries, and DIY tips sent six days a week. It's a common scene in many films set in medieval Europe: a wooden cart wheeling its way through a jeering crowd of townsfolk, taking a condemned prisoner to the gallows.

New York governor Kathy Hochul says she will propose a new law allowing limited autonomous vehicle pilots in smaller cities. Full-blown services could be next. As self-driving car services from Alphabet's Waymo, Amazon's Zoox, and Tesla have slowly, quietly expanded across the US, one big, important state has mostly stayed mum: New York . The union's fourth most populous state has some of the tightest laws governing autonomous vehicles, requiring companies approved to test in the state to only do so with a driver behind the wheel. There's no current path for companies to operate the sort of commercial robotaxi services like the sort seen in San Francisco or Las Vegas.

Driven by the right to be forgotten (RTBF), machine unlearning has become an essential requirement for privacy-preserving machine learning. However, its realization in decentralized federated learning (DFL) remains largely unexplored. In DFL, clients exchange local updates only with neighbors, causing model information to propagate and mix across the network. As a result, when a client requests data deletion, its influence is implicitly embedded throughout the system, making removal difficult without centralized coordination. We propose a novel certified unlearning framework for DFL based on Newton-style updates. Our approach first quantifies how a client's data influence propagates during training. Leveraging curvature information of the loss with respect to the target data, we then construct corrective updates using Newton-style approximations. To ensure scalability, we approximate second-order information via Fisher information matrices. The resulting updates are perturbed with calibrated noise and broadcast through the network to eliminate residual influence across clients. We theoretically prove that our approach satisfies the formal definition of certified unlearning, ensuring that the unlearned model is difficult to distinguish from a retrained model without the deleted data. We also establish utility bounds showing that the unlearned model remains close to retraining from scratch. Extensive experiments across diverse decentralized settings demonstrate the effectiveness and efficiency of our framework.
