Paired with reports and spottings of new model art, many speculated it was the long-awaited release of the GPT-4.1 model. It turned out to be a massive ChatGPT update that introduced new memory capabilities — but now, OpenAI’s new family of […] More

Kerry Wan/ZDNETClosing your Apple Watch’s activity rings could be good for your health. That’s according to a new data analysis in the Apple Heart and Movement Study, which found positive associations between activity rings’ closure and sleep, heart health, and mental well-being. The analysis of data, contributed by more than 140,000 participants, found that people who regularly closed their activity rings were 48% less likely to wake up frequently during the night, 73% less likely to experience an elevated resting heart rate, and 57% less likely to report elevated stress. Also: The best Apple Watches of 2025While Apple’s Heart and Movement Study’s findings are new, the notion that exercise is good for your sleep, heart, and stress isn’t. Smartwatches and fitness trackers like the Apple Watch encourage healthy and active behavior through constant reminders and incentives to exercise and make health-minded lifestyle decisions. That’s especially top of mind ahead of the Apple Watch’s 10th anniversary on April 24. On the smartwatch’s birthday, Apple Watch users can earn a Global Close Your Rings Day limited-edition award and an animated sticker for Messages by closing their activity rings. Go on a bike ride, get your steps in on a long walk, or swim laps in a pool; then share your activity using #CloseYourRings on social media.  More

Jack Wallen / Elyse Betters Picaro / ZDNETWhen I attended my first Linux convention, a company named Loki Games had a booth that was rather popular. Linux users flocked to the booth to see if a company could bring to the operating system one thing it was sorely missing: Games.Also: The best VPN for gaming: Expert tested and reviewedLoki Games had already delivered several titles by porting them from Windows to Linux. I played several of those games (I still have a few, I believe) and found them to be very well done. The problem wasn’t the company’s ability but the users’ willingness to pay for their products. In the end, Linux users didn’t want to buy software. They had become so accustomed to getting all of their software for free that the idea of shelling out hard-earned cash was shocking. Loki Games failed. After that, gaming on Linux stumbled and stuttered. Sure, there was Wine, and with some effort, you could get games to play. I remember the first time I was able to play Diablo on Linux — what a thrill and, back then, an accomplishment.Also: How to install Steam on Linux to start playing thousands of gamesToday, there’s Steam, which makes gaming on Linux exponentially easier. Steam also makes a large number of games available for Linux. Some Linux distributions have also taken it upon themselves to make gaming as easy as possible for users, such as Bazzite. More

Elyse Betters Picaro / ZDNETOn Thursday, the Financial Times reported that OpenAI has dramatically minimized its safety testing timeline.Also: The top 20 AI tools of 2025 – and the No. 1 thing to remember when you use themEight people who are either staff at the company or third-party testers told FT that they had “just days” to complete evaluations on new models — a process they say they would normally be given “several months” for. Competitive edgeEvaluations are what can surface model risks and other harms, such as whether a user could jailbreak a model to provide instructions for creating a bioweapon. For comparison, sources told FT that OpenAI gave them six months to review GPT-4 before it was released — and that they only found concerning capabilities after two months. Also: Is OpenAI doomed? Open-source models may crush it, warns expertSources added that OpenAI’s tests are not as thorough as they used to be and lack the necessary time and resources to properly catch and mitigate risks. “We had more thorough safety testing when [the technology] was less important,” one person, who is currently testing o3, the full version of o3-mini, told FT. They also described the shift as “reckless” and “a recipe for disaster.” Also: This new AI benchmark measures how much models lieThe sources attributed the rush to OpenAI’s desire to maintain a competitive edge, especially as open-weight models from competitors, like Chinese AI startup DeepSeek, gain more ground. OpenAI is rumored to be releasing o3 next week, which FT’s sources say rushed the timeline to under a week. More
