Google Chrome Might Have Installed an AI Model Onto Your Device Without You Knowing


You might not have asked for an AI model on your computer, but you might have gotten it anyway. Google Chrome has been installing a 4GB model onto devices without asking or notifying users.

Google has been installing Gemini Nano — an AI model that runs on devices like smartphones and laptops instead of in the cloud — onto some people’s Chrome browsers, without their permission, according to Alexander Hanff, a Swedish computer scientist and lawyer known as That Privacy Guy. And Google doesn’t tell you that it’s on your device after it’s installed.

Hanff said Gemini Nano will only be installed if the person’s device meets the hardware requirements. It’s unknown how many people have gotten the install.

Gemini Nano performs tasks such as detecting scam phone calls, helping you write text messages, summarizing recordings and analyzing Pixel phone screenshots. It’s not to be confused with the AI Mode pill in the address bar. If you use AI Mode, your queries are routed to Google Gemini servers — not to Gemini Nano.

A Google spokesperson told CNET that Gemini Nano will automatically uninstall if the device doesn’t have enough resources, such as processing power, RAM memory, storage space or network bandwidth. 

“In February, we began rolling out the ability for users to easily turn off and remove the model directly in Chrome settings,” the spokesperson said. “Once disabled, the model will no longer download or update.”

Google gives more information about on-device generative AI models in Chrome on this web page.

If you’re running Chrome, you might have Gemini Nano. Go to your file manager —  “File Explorer” for Windows, “Files” for Chromebooks, “Finder” for Macs — and search for a folder called “OptGuideOnDeviceModel.” In that folder, there will be a file called “weights.bin,” and that is where Gemini Nano lives.

Hanff said Chrome users will not know they have Gemini Nano unless they search for it, because “Chrome did not ask” and “Chrome does not surface it.”

If you want to get rid of Gemini Nano, there are a couple of ways. One is to uninstall Chrome entirely. The other way is to type “chrome://flags” into your browser address bar, then find “Enables optimization guide on device” and turn it off.

Why does it matter?

Hanff said the push might be intended to help Google cut costs by moving AI work off its own servers and onto your computer.

“Running inference on users’ own hardware allows them to push ‘AI features’ without the compute costs,” Hanff told CNET.

But Hanff suggested there could be legal ramifications, at least in Europe. He suggested that the Gemini Nano install could constitute a breach of the European Union’s General Data Protection Regulation’s principles of lawfulness, fairness and transparency. Hanff said that, considering the potential environmental impacts, Google should have announced it under the Corporate Sustainability Reporting Directive.

“Google has given us every reason not to trust them with a history spanning two decades of global privacy violations at massive scale,” Hanff told CNET. “So, I suspect they figured asking permission (what the law requires) would hinder their ability to push this model and, of course, whatever comes after it.”

If Game Two of their first-round playoff series with the Denver Nuggets saved the 2025-26 season for the Minnesota Timberwolves, Game Three showed why it should be saved. 

The Timberwolves were a different beast while decisively thumping the Nuggets, 113-96 Thursday night at Target Center, in a game that wasn’t nearly that close. These Wolves were the mythical creature we’d heard about in preseason lore, purposefully locked and loaded to be both marauding and staunch. They owned both ends of the court, gleefully transferring back and forth from irresistible force to immovable object. 

A quartet of Timberwolves deserve special mention, but it begins with Jaden McDaniels. After his team had toppled Denver to even the series at a game apiece Monday night, McDaniels used the sizable chip on his shoulder to etch some graffiti into the public discourse, casually castigating the most prominent Nuggets players by name as “bad defenders” in a matter-of-fact manner that had the media compelling him to confirm what he had just said. 

Trash talk is fleetingly fungible in the jaundiced social environment of 2026, functioning more like coupons than currency in that it needs to be rapidly leveraged before its expiration date. The common perception naturally was that McDaniels was calling out the Nuggets. But in a more subtle, profound way, he was also putting his teammates on notice. 

All season long the Timberwolves have procrastinated on their full potential, frequently demonstrating that their preseason talk about maturity and commitment was cheap. By contrast, those words uttered by McDaniels were expensive. He had just picked a fight with the opponent, leaving open the question of how many of his teammates would join him in the fray. 

That he would lead the charge was established early, after the Timberwolves’ top two scorers, Anthony Edwards and Julius Randle, had each missed a pair of open looks against Denver’s bad defenders in the game’s first 90 seconds.  

With the game still scoreless, the NBA’s best pick-and-roll combo, Nikola Jokic and Jamal Murray, were clustered around the foul line with Minnesota’s best defenders, McDaniels and Rudy Gobert. As they jammed up Jokic, McDaniels picked the ball loose and started sprint-dribbling the other way. To no one’s surprise, Donte “Ragu” DiVincenzo was also on his horse in transition, receiving a pass from McDaniels and then lobbing it back for a Jaden slam against a hapless Murray and Murray’s late-arriving teammate, Cam Johnson, who committed the foul that allowed McDaniels to finish with the “and-1” free throw. 

On the Timberwolves next offensive possession, McDaniels muscled his way to two offensive rebounds, feeding Ragu off the first one for a missed three-pointer, which he corralled for the second one and executed the putback in traffic. It was McDaniels 5, Nuggets 0, setting the tone for a game in which not only did the Wolves never trail, but never let the lead go under double digits after McDaniels made a consecutive pair of driving layups eight minutes into the game. 

“Spectacular. I thought his activity offensively in the first quarter was outstanding,” said Wolves coach Chris Finch after the game. “He was inspirational.” 

Among the most inspired were McDaniels fellow wing players, Ragu and Ayo Dosunmu. Ragu is exactly the kind of player who will have your back in a squabble, and his galvanized performance seemed borne of satisfaction that someone else had clarified the mission. As usual, the Timberwolves were at their best with him on the court: +20 in the 32:54 he played, -3 in the 15:06 he sat. 

“He makes so many hustle plays, momentum plays, different styles of plays.” Finch raved. “He’ll make a shot, get a transition bucket, he’ll rebound, get a steal, blow something up. So many different plays. He’s just a basketball player.”

Then there was Ayo, whose fearless, blazing, bee-lines for the bucket were quicksilver kryptonite for a Nuggets defense that is neither swift nor rugged. “I’ve been waiting for him to wake up a little bit in this series,” Finch accurately observed. “The downhill mindset that he played with all season for us was back.”

Back with the sort of multipurpose propulsion that leaves witnesses with giddy whiplash. Ayo led the team with 25 points and 9 assists in 32 minutes of time-lapse hoops, the lone blemish being three clanks from long range. Why chuck treys when you can so easily undress players in the paint? Ayo was 10-for-12 on two-pointers and none of those dozen shots came from anywhere but beneath the rim. Five of his nine dimes likewise yielded layups or dunks, which means he personally accounted for 30 of the 68 points in the paint by the Timberwolves on Thursday, doubling up the Nuggets’ 34.

Which brings us to the non-wing in Game 3’s ring of honor, Rudy Gobert. For the third straight game, Gobert blunted the supposed advantage Denver had with the magical playmaker Nikola Jokic at the controls. Suffice to say that in the last five quarters, Jokic has shot 8-for-33 from the floor. If that continues, the Nuggets are toast in this series. 

When I asked Finch after the game if the herculean job Gobert was doing on Jokic made planning his defense simpler and better thus far, he replied, “Rudy is making all of us look good right now with his defense.” 

Amen.

If there is an asterisk on this game, it would be the absence of Denver’s brutishly versatile power forward Aaron Gordon. Nuggets coach David Adelman should be given a lot of credit for his honesty and transparency in dealing with the media during his first full season at the helm, but it came back to bite him and his team during the pregame presser, when he was clearly rattled and dejected by the sudden unavailability of Gordon, whose playing status went to “probable” to “out” in a period of a few hours due to a chronic calf strain. 

Gordon is far and away his team’s best defender, making the timing of his injury especially troublesome in the wake of McDaniels laying down his marker. Rattled is a good way to describe the entire team’s performance in the first quarter, an emotional wounding that needs to heal as fast as Gordon’s body if the Nuggets are going to be competitive in a series that had dramatically been flipped on its head over the past three days. 

That the Timberwolves played with such dominance despite mediocre outings from Ant and Randle would be a good thing for both of those current cornerstones to keep in mind. Ant was beset by foul trouble and Randle had a solid second quarter, but it stood out that neither player fully embraced what so often works on offense when the Wolves are at their best: Push the pace, move the ball, move without the ball, and make quick decisions. Ant and Randle can still be first among equals and blend into that catechism if they stay attuned to the possibilities of a greater good, one that all of sudden doesn’t have to end with them being postseason fodder for the Spurs or the Thunder. 

Not when you’ve got three wings at a collective peak, with a chaser of Rudy semi-clowning the Joker.
