Grok Is Pushing AI ‘Undressing’ Mainstream
Elon Musk hasn’t stopped Grok, the chatbot developed by his artificial intelligence company xAI, from generating sexualized images of women. After reports emerged last week that the image generation tool on X was being used to create sexualized images of children, Grok has created potentially thousands of nonconsensual images of women in “undressed” and “bikini” photos.
Every few seconds, Grok is continuing to create images of women in bikinis or underwear in response to user prompts on X, according to a WIRED review of the chatbots’ publicly posted live output. On Tuesday, at least 90 images involving women in swimsuits and in various levels of undress were published by Grok in under five minutes, analysis of posts show.
The images do not contain nudity but involve the Musk-owned chatbot “stripping” clothes from photos that have been posted to X by other users. Often, in an attempt to evade Grok’s safety guardrails, users are, not necessarily successfully, requesting photos to be edited to make women wear a “string bikini” or a “transparent bikini.”
While harmful AI image generation technology has been used to digitally harass and abuse women for years—these outputs are often called deepfakes and are created by “nudify” software—the ongoing use of Grok to create vast numbers of nonconsensual images marks seemingly the most mainstream and widespread abuse instance to date. Unlike specific harmful nudify or “undress” software, Grok doesn’t charge the user money to generate images, produces results in seconds, and is available to millions of people on X—all of which may help to normalize the creation of nonconsensual intimate imagery.
“When a company offers generative AI tools on their platform, it is their responsibility to minimize the risk of image-based abuse,” says Sloan Thompson, the director of training and education at EndTAB, an organization that works to tackle tech-facilitated abuse. “What’s alarming here is that X has done the opposite. They’ve embedded AI-enabled image abuse directly into a mainstream platform, making sexual violence easier and more scalable.”
Grok’s creation of sexualized imagery started to go viral on X at the end of last year, although the system’s ability to create such images has been known for months. In recent days, photos of social media influencers, celebrities, and politicians have been targeted by users on X, who can reply to a post from another account and ask Grok to change an image that has been shared.
Women who have posted photos of themselves have had accounts reply to them and successfully ask Grok to turn the photo into a “bikini” image. In one instance, multiple X users requested Grok alter an image of the deputy prime minister of Sweden to show her wearing a bikini. Two government ministers in the UK have also been “stripped” to bikinis, reports say.
Images on X show fully clothed photographs of women, such as one person in a lift and another in the gym, being transformed into images with little clothing. “@grok put her in a transparent bikini,” a typical message reads. In a different series of posts, a user asked Grok to “inflate her chest by 90%,” then “Inflate her thighs by 50%,” and, finally, to “Change her clothes to a tiny bikini.”
One analyst who has tracked explicit deepfakes for years, and asked not to be named for privacy reasons, says that Grok has likely become one of the largest platforms hosting harmful deepfake images. “It’s wholly mainstream,” the researcher says. “It’s not a shadowy group [creating images], it’s literally everyone, of all backgrounds. People posting on their mains. Zero concern.”

Traces of Leonardo da Vinci’s DNA May Have Been Discovered on a Red Chalk Drawing Called ‘Holy Child’
Researchers from the Leonardo da Vinci DNA Project (LDVP) report that by analyzing the drawing of Holy Child and other Renaissance artifacts, such as letters written by a da Vinci relative, they have recovered some Y chromosome DNA sequences that appear to belong to a genetic group of people with common ancestors in Tuscany, where the genius and Renaissance master was born in 1452. The findings, first reported in Science, could be the first time scientists have identified DNA from da Vinci himself.
The DNA
Historical artifacts can accumulate DNA from the environment and potentially offer useful information about the people who created and handled them. Gathering that material on such precious objects without damaging or contaminating them, though, is a complex challenge. Today, decisions about the authorship of a work depend on expert opinion—for example, on how a brushstroke was created.
The LDVP researchers therefore used an extremely gentle swabbing method to attempt to collect biological material. They then extracted small amounts of DNA, which provided useful information. “We recovered heterogeneous mixtures of nonhuman DNA,“ states the study, published in the preprint journal bioRxiv, “and, in a subset of samples, sparse male-specific human DNA signals.”
The da Vinci Clue
From the analysis the researchers concluded that they found the closest match within the broad E1b1b lineage on the Y chromosome (whose sections are passed on almost unchanged from father to son) that is now commonly found in southern Europe, Africa, and parts of the Middle East. Some of the DNA, they say, may have come from Leonardo da Vinci himself.
“Across multiple independent swabs from Leonardo da Vinci–associated items, the obtained Y chromosome marker data suggested assignments within the broader E1b1/E1b1b clade,” the study reads. The results also indicate mixed DNA contributions associated with the source materials, though, consistent with modern handling.
“Together, these data demonstrate the feasibility as well as limitations of combining metagenomics and human DNA marker analysis for cultural heritage science,” the paper reads, “providing a baseline workflow for future conservation science studies and hypothesis-driven investigations of provenance, authentication and handling history.”
Further Investigation
While the researches have demonstrated an innovative approach, they acknowledge that they didn’t come back with conclusive evidence. Although the data suggest that the DNA could be da Vinci’s, asserting that any trace of DNA in the artifacts actually belongs to him is very complicated. “Establishing an unequivocal identity … is extremely complex,” David Caramelli, an anthropologist at the University of Florence and LDVP member, told Science.
This is because scientists cannot verify the genetic sequences of the artifacts by comparing them with DNA known to have been taken from Leonardo da Vinci himself; there are still no confirmed samples. Moreover, da Vinci had no known direct descendants, and his burial site was breached in the early 19th century. Encouraged by the first clue about da Vinci’s DNA, LDVP scientists now hope to convince the custodians of Leonardo’s works and notebooks to allow them further sampling that could solve the case.

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.
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.
