Dean Leitersdorf introduces himself over Zoom, then types a prompt that makes me feel like I've just taken psychedelic mushrooms: "wild west, cosmic, Roman Empire, golden, underwater." He feeds the words into an artificial intelligence model developed by his startup, Decart, which manipulates live video in real time. "I have no idea what's going to happen," Leitersdorf says with a laugh, shortly before transforming into a bizarre, gold-tinged, subaquatic version of Julius Caesar in a poncho. Leitersdorf already looks a bit wild--long hair tumbling down his back, a pen doing acrobatics in his fingers. As we talk, his onscreen image oscillates in surreal ways as the model tries to predict what each new frame should look like.

Roblox is rolling out new features aimed at making the platform safer for minors, including a revamped friend system, privacy tools, and age verification services users submit by recording a video selfie. In Roblox's old friend system, players have no distinction between people they know casually or online versus someone they consider a close friend. The platform's new tiered system introduces Connections and Trusted Connections specifically for people that players know and trust. To access Trusted Connections and its benefits, users first need to complete an age verification, which requires them to submit a video selfie. Once they've submitted their video, the company says it's run against an AI-driven "diverse dataset" to get an age estimation.

Isa Fulford, the research lead for OpenAI's new ChatGPT agent, needed to order a bunch of cupcakes, so she asked the AI tool to do it for her. "I was very specific about what I wanted, and it was a lot of cupcakes," she says. "That one took almost an hour--but it was easier than me doing it myself, because I didn't want to do it." OpenAI has launched a new agent for ChatGPT that uses a virtual browser to complete tasks and can generate downloadable files, specifically PowerPoint presentations and Excel spreadsheets. While not a full replacement for the Microsoft suite of workplace tools, the features included in this agent from OpenAI could obviate some users' reliance on Microsoft's enterprise software.

Hackers are stashing malware in a place that's largely out of the reach of most defenses--inside domain name system (DNS) records that map domain names to their corresponding numerical IP addresses. The practice allows malicious scripts and early-stage malware to fetch binary files without having to download them from suspicious sites or attach them to emails, where they frequently get quarantined by antivirus software. That's because traffic for DNS lookups often goes largely unmonitored by many security tools. Whereas web and email traffic is often closely scrutinized, DNS traffic largely represents a blind spot for such defenses. Researchers from DomainTools on Tuesday said they recently spotted the trick being used to host a malicious binary for Joke Screenmate, a strain of nuisance malware that interferes with normal and safe functions of a computer.

A new drug usually starts with a tragedy. Born in what is now Zimbabwe, the child of a mechanic and a radiology technician, Ray fled with his family to South Africa during the Zimbabwean War of Liberation. He remembers the journey there in 1980 in a convoy of armored cars. As the sun blazed down, a soldier taught 8-year-old Ray how to fire a machine gun. But his mother kept having to stop.

For the past few weeks, the AI-powered ElliQ companion robot has perched on the end of my desk. Designed by Intuition Robotics for seniors living alone, this proactive animatronic chats to me throughout the day, checking how I'm feeling, suggesting "fun" activities, and prodding me to be more active and sociable. While it can be annoying, I've grown attached to ElliQ despite myself, and I can see the positive potential. According to the US Census Bureau, around 16 million elders (over 65) live alone in the country, and up to a third report feelings of loneliness. Multiple studies have shown that social isolation harms mental and physical health, increasing blood pressure, depression, weight gain, alcohol and drug use, and decreasing physical activity, cognition, heart health, and sleep.

AI is "not my thing," President Donald Trump admitted during a speech in Pittsburgh on Tuesday. However, the president said during his remarks at the Energy and Innovation Summit, his advisors had told him just how important energy was to the future of AI. "You need double the electric of what we have right now, and maybe even more than that," Trump said, recalling a conversation with "David"--most likely White House AI czar David Sacks, a panelist at the summit. "I said, what, are you kidding? That's double the electric that we have. Take everything we have and double it."

A new kind of artificial intelligence agent, trained to understand how software is built by gorging on a company's data and learning how this leads to an end product, could be both a more capable software assistant and a small step towards much smarter AI. The new agent, called Asimov, was developed by Reflection, a small but ambitious startup confounded by top AI researchers from Google. Asimov reads code as well as emails, Slack messages, project updates and other documentation with the goal of learning how all this leads together to produce a finished piece of software. Reflection's ultimate goal is building superintelligent AI--something that other leading AI labs say they are working towards. Meta recently created a new Superintelligence Lab, promising huge sums to researchers interested in joining its new effort.

I'm genuinely not sure if large language models--often referred to as "AI" in shorthand--are the future of computing. But I also don't think chatbots are how people will use this technology in the years to come. Substage, an indie Mac application by developer Joseph Humfrey, is a simple app that points to a potential alternative--one that's useful right now. This application floats under every Finder window, meaning you see it only when you're browsing files in macOS. You can type English-language sentences into it to do things like rename, convert, or compress files.

OpenAI researcher Jason Wei is joining Meta's new superintelligence lab, according to multiple sources familiar with the matter. Wei worked on OpenAI's o3 and deep research models, according to his personal website. He joined OpenAI in 2023 after a stint at Google, where he worked on chain-of-thought research, which involves training an AI model to process complex queries step-by-step. At OpenAI, Wei became a self-described "diehard" for reinforcement learning, a method of training or refining an AI model with positive or negative feedback. It's become a promising area of AI research--one that several of the researchers Meta has hired for its superintelligence team specialize in.
