Jensen Huang Says Nvidia’s New Vera Rubin Chips Are in ‘Full Production’
Nvidia CEO Jensen Huang says that the company’s next-generation AI superchip platform, Vera Rubin, is on schedule to begin arriving to customers later this year. “Today, I can tell you that Vera Rubin is in full production,” Huang said during a press event on Monday at the annual CES technology trade show in Las Vegas.
Rubin will cut the cost of running AI models to about one-tenth of Nvidia’s current leading chip system, Blackwell, the company told analysts and journalists during a call on Sunday. Nvidia also said Rubin can train certain large models using roughly one-fourth as many chips as Blackwell requires. Taken together, those gains could make advanced AI systems significantly cheaper to operate and make it harder for Nvidia’s customers to justify moving away from its hardware.
Nvidia said on the call that two of its existing partners, Microsoft and CoreWeave, will be among the first companies to begin offering services powered by Rubin chips later this year. Two major AI data centers that Microsoft is currently building in Georgia and Wisconsin will eventually include thousands of Rubin chips, Nvidia added. Some of Nvidia’s partners have started running their next-generation AI models on early Rubin systems, the company said.
The semiconductor giant also said it’s working with Red Hat, which makes open source enterprise software for banks, automakers, airlines, and government agencies, to offer more products that will run on the new Rubin chip system.
Nvidia’s latest chip platform is named after Vera Rubin, an American astronomer who reshaped how scientists understand the properties of galaxies. The system includes six different chips, including the Rubin GPU and a Vera CPU, both of which are built using Taiwan Semiconductor Manufacturing Company’s 3-nanometer fabrication process and the most advanced bandwidth memory technology available. Nvidia’s sixth-generation interconnect and switching technologies link the various chips together.
Each part of this chip system is “completely revolutionary and the best of its kind,” Huang proclaimed during the company’s CES press conference.
Nvidia has been developing the Rubin system for years, and Huang first announced the chips were coming during a keynote speech in 2024. Last year, the company said that systems built on Rubin would begin arriving in the second half of 2026.
It’s unclear exactly what Nvidia means by saying that Vera Rubin is in “full production.” Typically, production for chips this advanced—which Nvidia is building with its longtime partner TSMC—starts at low volume while the chips go through testing and validation and ramps up at a later stage.

What’s Going on With Smart Rings?
If you’ve been following last year’s smart ring drama, you may have seen that the number of health-tracking rings you can buy has shrunk since October 21, 2025.
As we reported in August, the US International Trade Commission ruled in favor of Oura in a patent case in which Oura alleged that its competitors RingConn and Ultrahuman had infringed on the company’s patent for a smart ring that tracks health and fitness stats. Oura’s victory subsequently led to RingConn and Ultrahuman being banned from importing new rings into the US.
The lawsuit was bad news for both Oura competitors, and especially Ultrahuman, which had planned to expand its US-based manufacturing facility to meet growing market demand (and ostensibly to also get around the new US tariffs). Ultrahuman is distinguished from Oura in that its smart ring does not have a subscription; Oura users pay $6 per month to use its rings.
I caught up briefly with Ultrahuman’s chief business officer, Bhuvan Srinivasan, to clarify the company’s next steps to address the US market, and find out more about the latest smart ring squabbles.
Why Were the Rings Banned?
The ITC ruled that RingConn and Ultrahuman had infringed on the 178 patent, which protects a specific ring hardware design—for example, if the ring has a layered arrangement with internal and external components housing interior electrical components.
If you think this is a surprisingly broad description that can cover … well, pretty much any smart ring, or a wide range of electronic devices in general, you are correct. Over the past few years, many smart ring manufacturers have been embroiled in legal disputes over this patent.
This has panned out in a few different ways. In 2024, Oura announced that it had reached a multi-year licensing agreement with Circular, the French smart ring manufacturer, that would allow Circular to continue selling new rings in the US. (This move looks a little less generous when you consider that my two-week testing period of the Circular Ring 2 was plagued with server and connection issues.)
Also in 2024, Samsung attempted to preemptively sue Oura against future patent infringement claims in a case which a judge dismissed. Samsung’s concerns were not unwarranted. In late 2025, Oura then filed another complaint against Samsung (the Galaxy Ring), Reebok (the Reebok smart ring), Zepp Health (Amazfit ring), and Nexxbase (the Luna Ring). Oura then reached a licensing agreement with RingConn and another competitor, Omate, that would allow the company to continue selling rings in the United States.

How to Build a Home Pilates Setup That Feels Studio-Level
When Joseph Pilates developed what he first called Contrology in the early 20th century, there were no dedicated studios or intimidating contraptions. There wasn’t even a reformer yet. (That came later, improvised from leather straps and hospital bed frames.) The idea was simple then, and it still is now: Pilates asks you to work with what you already have. Your body does the work, and a mat just makes it more comfortable.
Pilates is about moving with intention. Total body exercises are rooted in precision and balance, favoring slow, controlled movements over momentum or strength. Full range of motion, emphasizing time under tension, deep core engagement, and uniformity of mind, body, and spirit are emphasized. It sounds peaceful, but it’s not exactly the easiest workout.
The right gear won’t do the workout for you, but it can make it more comfortable, more effective, and frankly, more fun. Below, we’ve gathered the best Pilates equipment worth having for home workouts, whether you’re a beginner or deep in your Pilates princess era.

Pilates Clothes
Nothing motivates me to work out quite like a great Pilates outfit. You can technically wear just about anything, but I would stick to more fitted activewear, so your Pilates instructor can check your form. Avoid loose or oversized clothing, and prioritize stretchy fabrics that won’t restrict movement. This lineup of athleisure has been tried and tested in Pilates; they move well, feel comfortable, and hold up every session.
If you buy one thing, make it grippy socks. Whether you’re on a mat or a reformer machine, those rubberized soles help prevent slipping and sliding, giving you better traction and stability during movements. A good pair can also offer light cushioning and arch support. If you’re practicing in a shared studio or using communal equipment, breathable Pilates socks are a hygienic upgrade, too.
We want our bottoms to stay put through roll-ups, leg circles, and long pulses, without digging or losing shape. They also need to be squat-proof. High-waisted leggings (full-length or capri) made from a soft, stretchy fabric are ideal for Pilates and other low-impact workouts. Biker shorts also work, but in a heated class, an extra layer of fabric can help maintain grip on props during leg work.
These are the best leggings for Pilates based on our testing, including a Lululemon biker short we love. For more favorites, check out our Best Leggings guide.
For Pilates, look for low- to medium-impact styles that are typically supportive without feeling compressive. I gravitate toward wide bands with no underwires that won’t dig in during floor work, but I’m also aware that those features might not be supportive for bigger busts. These are our top favorites, including a posture-correcting bra if alignment or lower back pain is a concern. For more picks, check out our Best Sports Bras guide.
An all-in-one jumpsuit with a built-in bra takes the guesswork out of getting dressed for Pilates. Our favorites offer supportive, comfortable coverage that moves with you from warm-up to cooldown.
Pilates-Specific Gear
You can absolutely do Pilates with nothing but yourself, but if you want to turn up the intensity or vary your workout routines, here are a few must-haves.
Exercise mats are essential because they deliver much-needed padding to cushion your joints during floor work. The proper ones are designed with a grippy, textured surface for added traction. They keep you steady, supporting better control. And they serve as a protective barrier between your skin and the yucky floor.
I also always need a towel when working out, and if you’re taking a heated class, this is especially necessary to absorb sweat. Pro tip: You can also turn your towel into a resistance band by twisting it and pulling against it. For more picks, check out our Best Yoga Mats guide.
You don’t need to splurge on a $2,000 reformer to practice Pilates at home. I take heated mat Pilates at my local fitness studio twice a week, and we usually use a combination of props: an exercise ball, Pilates ring (aka. a magic circle), and light weights. I like to use 2- or 3-pound dumbbells, but wrist and ankle weights don’t require grip strength and still add extra intensity to your full-body Pilates workout. Core sliders, which go under your hands or feet, add resistance to your movements and are an affordable alternative to the springs of a reformer.
We’ve spotlighted a few of our favorites below, but you can find more tested picks in our Best Reusable Water Bottles guide.
