Google Chrome silently installs 4 GB Gemini Nano AI model
That Privacy Guy and Sinaptica found Google Chrome automatically downloads a 4 GB Gemini Nano language-model weights file and stores it in a folder named OptGuideOnDeviceM. The downloads began in May 2026 and have placed the file on millions of machines without a visible opt-in; deleting the file causes Chrome to re-download it unless users disable Chrome's AI features via chrome://flags or apply an enterprise policy. Researchers warn the push consumes significant bandwidth and local storage, and That Privacy Guy estimated the cumulative climate impact could equal the CO2 emissions of roughly 1,300 European cars. This matters because unexpected 4 GB downloads strain devices with limited storage or metered connections, raise privacy and compliance concerns, and give users little control over on-device AI components.
Chrome is reaching into users' machines and writing a 4 GB on-device AI model file to disk without asking. It is the weights for Gemini Nano, Google's on-device LLM. Chrome did not ask. Chrome does not surface it. If the user deletes it, Chrome re-downloads it. www.thatprivacyguy.com/blog/chrome-...
Delete Chrome. You have other options.
I'm so glad Firefox decided to implement, at users' insistence, a "turn off all AI bullshit" killswitch If it ever scraps it, I'll just get a web browser that works through a Linux terminal or something
The irony of this blogger unabashedly using an AI image as the header for this blog post.
If you live in California, this is a violation of the California Consumer Protection Act. The very act of reinstalling it after it's been deleted is covered under the Dark Acts provision. You can file a complaint here. cppa.ca.gov/webapplicati...
I am mad my device permitted this without approval.
Stop using chrome. Straight up just download a fork of it or firefox. Preferably waterfox.
Okay that should be illegal
If anyone reading this thread uses Chrome, this, via @draglikepull.bsky.social, seems very helpful: www.tomsguide.com/ai/check-you...
the re-download part is the real issue. if users delete it, Chrome reinstalls it automatically—that removes any pretense of choice. "we're putting this on your machine" becomes "we control this space on your machine." that's a design decision, not a bug.
These idiots really never think about enterprise environments which is where all their money comes from? This is literally malware. What are they using to bypass installs restrictions?
lmao the article thumbnail (and let’s be real, the article itself most likely) is AI generated Clown website.
Eek! The automatic re-installation is malware behavior. At 4GB, bloatware too. I switch between Vivaldi and Safari, but since Apple is AI-pilled, it’s fair to assume they’ll be moving in the same direction as Chrome for Safari, so I think I’ll wanna transfer my bookmarks and adopt Vivaldi 100%.
Implications for thin clients used in environments where that space really isn't there and those devices absolutely NEED to work consistently. Healthcare, flight, infrastructure.
Making a note to check and see if this is this is the thing that's filling up all the space on my C: drive no matter how much stuff I delete.
I remember when everyone lost it when Apple pushed a free U2 album to all devices.
This is the setting that might disable this. It might not work, because Google.
Google dumping its "don't be evil" motto was a pretty clear sign
This sounds like something a lot of people could sue over.
Okay, fuck this, anyone know of a second web browser to export all chrome stuff to? I like to use firefox for other stuff
Lol who tf is still using chrome?
why is the header art for this article an AI generated image?
How can I destroy the ai
if y'all need to use Chrome for work shit like I do, here's how I deleted the file on my macbook bsky.app/profile/mpgp...
It feels like every day Google puts some fucked up shit somewhere I don't want it. I know I can't get away from AI but I'm getting close to switching to apple just because I'm so pissed off.
Tapping the sign, Google. m.youtube.com/watch?v=oQbe...
Glad I use LibreWolf (a privacy-focused fork of Firefox) and Ungoogled Chromium (for those sites that don't play nice with Firefox browsers)
This is weird, because there I was thinking that the Computer Misuse Act 1990 explicitly made this illegal.
"Don't be evil" was a farce from the start.
"At Chrome's scale, the climate bill for one model push, paid in atmospheric CO2 by the entire planet, is between six thousand and sixty thousand tonnes of CO2-equivalent emissions, depending on how many devices receive the push."
how he fuck is that going to work?? just because its a small model doesnt mean it doesnt need compute.... you thought chrome was a resource hog now?? this is going to be pegging your cpu non-stop on lower end hardware..... #phrasing #isaidwhatisaid
How is this NOT ciminal?? It's like entering your house without permission, taking food out of your fridge and then shitting on the table, on top of it all!
The Weyland-Yutani Corporation is at it again...
I was wondering why Gemini was back in my devices.... I have a tablet playing lore videos all night and Gemini keeps unlocking itself and screaming at me in the middle of the night Guess I'll just have to delete Chrome because fuck that, nobody wants an AI that wakes you up at 3AM for no reason
Sounds like a class action lawsuit waiting to happen.
🤔 Perhaps a workaround is to close Chrome, delete the AI file, then create a new file by the same filename and use administrator privileges to remove Modify permissions from that file for whatever user Chrome runs as.
this is wild - I just checked, and sure enough, there is 4GB file sitting there.
I know I’ll get hate mail but folks, Safari is good and very good if you like your battery.
Questions from a dum dum: I switched to floorp about a year ago (how do folks feel about floorp these days?) and every once in a while I need to switch to chrome for stuff like logging into government websites or healthcare provider video call apps. What do I use instead of chrome for that stuff?
Is it related to this? bsky.app/profile/hydr...
Can I see that U2 album again?
Welp... Uninstalled chrome after using it for a decade. Firefox it is.
I am not finding this file on my Windows desktop, where I have Chrome Version 147.0.7727.138 installed (though I use Firefox 99% of the time, as now).
oh dude i love botnets
Has anyone verified this? I could not find the directory on Windows 10 in ...\AppData\Local\Google\Chrome\User Data I do have the setting turned off: chrome://settings/ai/historySearch Also, which chrome://flags should I also try disabling? The article does not mention any.
While this is an overreach, surely it's irrelevant unless you have the hardware for it to execute anyway? I only use Chrome for a couple of sites that Firefox bulks at, but I'm sure my c.2012 core i3 w/ no GPU isn't gonna be running any genAI processes unawares, nor is my S5 Neo. GLWT, Google!
If I have it, can I delete it?
What does ”weights” mean in this context?
this basically just lets Chrome do the same things your phone's TPU can do locally, using your own hardware, without having to do it in a datacenter it's not really for "genAI" stuff, more like voice recognition, OCR, etc its not as nefarious as it looks, but vendors should communicate better!
Can one still deinstall Chrome? Or will it re-download it as well ...
Yeah this should be the last straw with Chrome for users who care about privacy and security.
Thank you so much for sharing this.
Making sure to uninstall Chrome tonight. I only kept it for websites too broken to load in Firefox anyway.
Google Chrome silently installs a 4 GB Gemini Nano AI model on your device ❌ No consent ❌ No opt-in ❌ No real opt-out for regular users This isn’t a small experiment & it’s on billions of devices. ➡️ Read more: www.thatprivacyguy.com/blog/chrome-...
And per the article "Re-installs itself if the user removes it manually, every time Claude Desktop is launched." Hey Google you already tried to put ai in my mail which I had declined but somehow it came back. Now this for Chrome. Get your shitty AI out of my computer. I do not want it.
Linux + Firefox. FOSS or GTFO There is no other way anymore
People still use google chrome?
Asking a serious question… doesn’t MS do that with copilot? It seems every major player has their AI model being forced on us… even Alexa was forcibly upgraded to “AI” which had to be opted out of.
Obligatory "NixOS fixes this" comment.
So tired of the tech bro invasive monitoring that I've finally been migrating for two years now over to Linux. Fiinding Mint to be easiest in migration. Proton Mail is great for those who don't like to be data mined.
I don't see any file called that on Mac OS
It's actually time to move off of Google Chrome completely, all devices. Some may have gripes with Firefox having AI stuff, but you can toggle it all off easily in settings. Find an option soon. This however? There's not much to be done to negate Google just reflipping switches. Get off Chrome.
On top of that, devs have made add-ons to Firefox that can filter a ton of ai material off your browsing experience! Imperfect but better than chrome.
Omg that's so disgusting what the actual fuck!? I don't consent to being part of the ai farm ugh
step 1: why the fuck do you use Google Chrome in the first place?
get LibreWolf or any other decent opensource browser that supports actual adblocks instead of the neutered chrome crap and be free of big corpos in your browser
about 90% of internet users use google chrome because they're not IT professionals/terminally online the same reason they use google anything; because it's the familiar name, it's dominant, and it's default.
