AI This Week

OpenAI has launched ChatGPT Health, a new feature in the US that analyzes personal medical records. The system can also review data from health apps like Apple Health and MyFitnessPal to provide users with personalized advice. OpenAI states the new feature is not for diagnosis or treatment. The company also claims health-related conversations will be stored separately and will not be used to train its AI models. Currently available to a small group of US users via a waitlist, the feature has not been introduced in the UK or Europe, which have stricter data protection rules

A new artificial intelligence model can forecast a person’s risk for serious diseases, including dementia and heart failure, using data from a single night of sleep. Researchers developed the system, called SleepFM, by training it on a vast library of over half a million hours of sleep studies from 65,000 individuals. The model examines complex biological signals recorded overnight, including brain waves, heart rhythms, and breathing patterns. From this single snapshot, it identifies subtle indicators of future health problems. The results are startling. SleepFM predicted all-cause mortality with a C-index of 0.84 and dementia at 0.85. It also demonstrated strong predictive performance for heart attack, stroke, and chronic kidney disease. A novel design allows it to function effectively even when a patient’s sleep data is incomplete.

The world’s largest technology conference is presenting the next wave of gadgets in Las Vegas. CES 2026 is filled with advancements in artificial intelligence, from a new AI pet that physically grows as you care for it to a smart ring that records and transcribes your work meetings. Robotics also had a key presence. Boston Dynamics debuted its new Atlas robot, and Qualcomm-powered humanoids demonstrated backward-bending flexibility. Other notable reveals include LG’s ultra-thin wallpaper TV, a pocket-sized lab that detects food allergens, and exoskeletons built to make hiking easier. Samsung also exhibited a creaseless foldable phone concept and a massive 130-inch television. 

Amazon pushed its AI ambitions into new territory with a suite of updates that bring its advanced assistant beyond the smart speaker and into browsers, phones, and wearable tech. The company rolled out a redesigned Alexa mobile app that makes the assistant central to the experience and launched Alexa+ in web browsers, letting users chat, upload documents, control calendars and smart devices, and even book tasks. It also revealed progress on Bee, a wearable AI that transcribes conversations and offers insights. These moves signal a fresh push to catch up with popular AI rivals and leverage its huge installed device base.

Elon Musk confirmed xAI acquired a third facility, dubbed “Macrohardrr,” pushing its AI training capacity toward a massive 2 gigawatts. The purchase significantly expands the company’s growing data center footprint in the Memphis area, a central piece of its Colossus AI infrastructure project. xAI is financing this ambition with aggressive fundraising efforts. Recent reports indicate the company is in advanced talks to raise about $15 billion in equity funding. The expansion gains further momentum from important government contracts. The U.S. Department of War recently struck a deal to deploy xAI’s Grok models on its official defense platform, marking a key adoption of the technology.
