Google Chrome silently installs a 4 GB AI model on your device without consent - https://news.ycombinator.com/item?id=48019219 - May 2026 (1143 comments)

IMO If you're into tech and still use Chrome*, that's on you. If you are not, you probably don't really care unless you need extra space on your PC.

*Except in your job, since you probably obligated to use.

Switched from firefox few months ago, I don't like google, but firefox has only few percent of market share currenly, many pages simply do not work properly with it, plus it has bugs on macos (like onmousover stuff), which simply make it unusable. Safari is fine, but also many websites (which sometimes you need to use like banking or gov) are not tested on it. The overall browsers situation is less than ideal.

dinkleberg•about 3 hours ago

That is weird, I've daily driven firefox for the better part of a decade (aside from when my employers have required chrome) and seldom encounter issues. I'm curious where you're hitting these. In fact, since ublock origin got removed from Chrome, the experience is far better on firefox.

Also, if everyone chooses to not use firefox because it has low market share, it'll remain low market share forever.

I use firefox on mac and I have simply no clue what you're talking about. Tons of people use firefox on mac quite successfully...

The only page that I know of that doesn't work is google earth - it doesn't work on linux either. (Technically it does, just incredibly laggy compared to chrome)

I can't think of a single macos specific bug. Or a single mouse over related bug.

jackb4040•about 3 hours ago

I think it's a stretch to call firefox on mac "unusable". Like once a month I'll have something not work, and half the time it also doesn't work in chromium (both are the developer's fault). And when it does work in chromium, browsers are free so just switch over there and switch back. And to top it off, there are endless free flavors of chromium like brave etc, that virtually never have compatibility issues without needing to go full google.

maccard•about 3 hours ago

I’ve been a daily Firefox user on macOS and windows for a decade. I can count on one hand the number of sites that don’t work.

What sites do you have in mind?

werdnapk•about 3 hours ago

I have been using Firefox for years (decades) and I rarely encounter a page or site that doesn't work... a handful perhaps, but it's a complete non-issue for me. If anything, my ad-blocker can sometimes cause issues and I'll disable that and everything is good again.

bornfreddy•about 2 hours ago

> ...many pages simply do not work properly with it,...

Using Google's websites much, are we? FF works great everywhere except there. I think the official term for the bugs on these pages is "oops"...

I use FF everywhere except on G pages, where I use Brave.

404mm•about 3 hours ago

Technically speaking, Safari is the second most used browser. It’s quite surprising how often I get these “unsupported browser” popups. I still use it as my primary and have FF as a backup. No Chrome needed.

ngetchell•about 3 hours ago

Don't be so dramatic. Firefox on macOS is perfectly usable.

nickthegreek•about 3 hours ago

daily drive Zen on macos with zero issues and quality adblocking support.

cdmckay•about 3 hours ago

Really? I use Firefox as my personal browser and everything works fine, including Google sites. Very rarely there’s a government site that needs Chrome, but I definitely wouldn’t say it’s “many” sites.

jrflo•about 3 hours ago

Ever since IO earlier this year when google showed their AI strategy I switched to firefox and duckduckgo and couldn't be happier with the decision. I am by no means anti-AI but users should be able to choose when they want to use these tools, google seems to want to shove it down everyone's throat.

encomiast•about 3 hours ago

Did a similar thing, but went with Kagi + Orion. Also happy to have a few more free cycles from not thinking about Google.

sheept•about 3 hours ago

Any page can silently trigger an additional multi-gigabyte download for Chrome users by just calling this API:

    await LanguageModel.create()

Since the model is installed once per browser, LanguageModel.availability() could probably also be used for fingerprinting.

tantalor•about 3 hours ago

Indeed, you could even do something like this:

    await fetch("/multi-gigabyte-download");

It even works on non-Chrome browsers.

i think the point is that one actually burns disk space, while the other is just a nuisance for people on plans with limited data

gruez•about 2 hours ago

You can store up to 80% of free disk space with indexeddb

DennisAleynikov•about 2 hours ago

using a browser is an easy way to burn disk space and limited data

light browsing is not a thing unless you somehow ensure javascript is disabled and all downloads are blocked

bri3d•about 3 hours ago

Just the availability wouldn't be that bad from a fingerprinting standpoint (getting one bit that a majority of Chrome users have is just the same bits you already have, usually), except, it also exposes whether the underlying hardware is "eligible," and once it's running, you can also benchmark the language model performance. It's a mess. I think it might also be broken and work in iframes, which would be an even bigger mess; there are a few bug reports suggesting this although many of them look like slop.

This feature was massively bungled; I actually don't overall hate the idea of it (having a shared, pre-downloaded model that can run effectively from JS is kind of awesome versus sites downloading stuff into LocalStorage to use with hacked up wasm/webgl inference engines), but it really, really needed a permissions dialog and a proper anti-fingerprinting model.

tantalor•about 3 hours ago

> really needed a permissions dialog

Why?

bri3d•about 3 hours ago

Users with data caps are an obvious reason, for example, see this frustrated user report here: https://support.google.com/chrome/thread/415181794/chrome-al... .

To your point about `fetch` in the sibling comment; yes, I would also be annoyed by a website which downloaded 4GB in the background without asking me, too.

I don't think this is some moral outrage, to be clear; it's well within Google's rights, it doesn't seem "sketchy" at all, and it is kind of a cool feature, but it feels like they could have done a lot better by just making it opt-in and a little less fingerprintable.

intellectronica•about 3 hours ago

In their defense, it's an astonishingly good model for this size and you can use it for all sorts of cool stuff.

yeah I'm lowkey pissed off people keep insulting google for giving them an offline version of coding enabled wikipedia that they get literally 0 data analytics from (just turn your wifi and ethernet off and use it offline after downloading it)

what part of the 4Gb file offended people?

the fact that ai runs on the edge reliably now?

Memory prices will adjust accordingly as this becomes the norm.

This is the kind of bootlicker that will usher in the new distopia.

Thanks

DennisAleynikov•about 2 hours ago

you're welcome for the total lack of reading comprehension on your part.

the edgy kids all hate google we get it but how the fk is a free offline ai model even a bad thing for privacy or even benefitting google in any way other than giving away privacy preserving tech for free

they obviously aren't good intentioned here, and benefit from the aggregate of data but OpenAI and Anthropic might as well be enemies of all humanity given they contribute nothing back to the knowledge that is useable offline without their exorbitant api costs

google should be better about their more evil tendencies but they now have sufficient competition that bootlicking is not an important thing to point out in the fight over open source(ish) models that allow people more freedom not less

its all moot when nobody can afford hardware in the first place that can run ai models so I guess I'm just yelling into the void here

ghurtado•about 3 hours ago

That does nothing to defend Google since the quality of the model is irrelevant to the accusation.

imnes•about 1 hour ago

The accusation that they pushed a new feature to Chrome users? They do that all the time? Why is this one alarming / needs special consent?

expedition32•about 3 hours ago

You'd think that if a technology is so good you don't need to force it on people.

scottyah•38 minutes ago

It's not forced on people, get a grip. It's a free feature on a free browser, just like all the other features.

ghurtado•about 3 hours ago

It certainly shouldn't require masses of blank eyed fans all making highly emotional pleads to protect the sensitivity of their favorite logo.

That's gross even by Microsoft standards.

To prevent Chrome from automatically downloading the model, go to Settings → On-device AI.

The “Local AI” toggle is enabled. Chrome never asked for my consent to enable it.

mrinterweb•about 3 hours ago

I'm a big fan of local models, and moving inference from the cloud to local machines is great, but there's a couple potential problems with this. LLMs take significant (V)RAM resources to run (which is in short supply on consumer hardware), and we don't know that Google won't send local conversation logs to their own servers (kind of surprised if they don't). So if you think you're having a private local conversation in Chrome, I wouldn't be so sure.

satvikpendem•about 3 hours ago

I personally use Firefox mainly due to extension support so I don't experience this. However, as a developer, the embedded Gemma local model in Chrome is vastly better to be included as a one time download than it is to download an AI model for every site you visit, as AI and especially local AI becomes increasingly more common. It is the same idea that Apple and Android and Windows have with their built-in foundation models in the OS. So in that case I can appreciate what Chrome is doing, as it will be saving a lot of bandwidth over time.

People have asked me what use cases this has, and I've been making little apps with on-device AI such as a calorie estimator and tracker for food, or a page summarizer or translated (the latter of which Firefox actually already has using a local model). Why pay for a cloud model when the user has a perfectly good model themselves?

imnes•about 1 hour ago

Serious question - why would Google need to ask user consent to push a new feature / update to Chrome?

There's been a lot of new tech introduced through Chrome and eventually widely adopted and available everywhere. Without requiring user consent.

QUIC + HTTP/3, WebP, Service Workers / PWAs, WASM, WebRTC, View Transitions API

This feels like just another step of "make this new capability widely available so developers can adopt it if they want."

This one seems to be all on-device local capabilities. Not calling additional APIs or sending data off-device.

Is the argument just around "Don't use 4gb of drive space without asking me first"? What other issues does this introduce?

judge2020•about 1 hour ago

Main externality is that this will use 4gb and X megabytes/gigabytes of RAM on the billions of devices that use Chrome. If RAM and disk usage needs have gone up linearly in the past decade, this technically causes a momentary immediate jump in those needs, although people still probably would only adjust on their regular upgrade cadence, maybe slightly faster than normal.

*although this 4gb is probably very likely to go up even more, maybe 8, 16gb models - if the disk space is there, and the computer has the power to use bigger models, I don't see why Google wouldn't ship better more capable on-device models when possible (other than profit motive to push more non-local-ai requiring a Google One AI subscription).

*this idea works absent of the recent AI datacenter-based demand for NAND and DRAM. If anything consumers are avoiding buying NAND or DRAM right now due to the prices.

judge2020•about 3 hours ago

Only problem is that it doesn’t prompt “do you want to download this/enable AI”, right? Otherwise, local AI is exactly what most people want instead of needing to pay rent to big tech companies for AI use*. Open-weight models would also be nice, but I imagine the people who care about that _and_ want to use Chrome are using Chromium or de-googled Chromium.

* other than how everyone is already paying rent in the form of increased energy costs due to increased demand from this massive ramp of data center development everywhere, regardless of if they want to use AI or not

From a year ago. They talked about adding the ability for Chrome to install Gemini Nano on-demand when a web app wants to use it. I guess this is the next step, making it always available by default.

Thanks! Very informative. Lot of new details including the answer from Google and several experiments

gumby271•about 3 hours ago

I'm sorry but the AI model that was forced to write this article is struggling to explain why this is a problem. I get that a chrome update that suddenly balloons to 4gb+ is stupid, that's fair, but I'm not sure I understand the rest of the issues. They don't like the off-device AI features Google is forcing into everything, but they also don't like the on-device AI features since they don't do enough?

Aside from taking up a lot of space as a web browser, I'm not sure I get it. Their explanation that Apple's version of this is fine but Google's isn't is wild too.

rvnx•about 2 hours ago

The reality is that the move is great, it's a very cool and nice stuff, just that it takes bandwidth and space without letting the user know.

A solution:

New AI features are available for use offline, they will make you able to translate offline, get answers, summaries, etc, would you like to download / install them (~4 GB)?

It is going to fix the experience in the UI. It's a significant misstep by Google in its form (probably lazy/hasted/bureaucratic release), but on the move itself, this is actually a very user-friendly initiative from Google.

It's quite unfair in that specific case to say that Google = evil, and when Qwen = good. It's just about informing the user better so the bandwidth and space is not wasted. Giving user choice.

They will fix it eventually, especially after raising the issue.

But shouting here "Google = bad, me uninstall Google, if you use Google Chrome you are an idiot" are not a productive feedback for a product owner there.

gumby271•about 2 hours ago

> But saying "Google = bad, me uninstall Google, if you use Google Chrome you are an idiot" are not a productive feedback for a product owner there.

I wasn't? I hope that wasn't directed at me since we seem to kind of agree otherwise.

Unfortunately the vast majority of Chrome users wont understand that prompt. Google decided that the Chrome installer should be 4GB, that seems like a large web browser, but is it that crazy compared to anything else? Teams on my Mac is taking 1GB+ just in Applications (not to say I'm terribly happy about that). Chrome installs its own updates and has for a very long time, ensuring we dont have to support super old browser versions, I'm not sure where the line is.

rvnx•40 minutes ago

No no, it wasn't against you, in fact I used your comment to piggy-back on "my"/our vision :)

kccqzy•about 3 hours ago

Google’s PR team is so bad at managing their reputation that their response wouldn’t have mattered. Apple can download a 4GB Apple Intelligence model onto your phone (which likely has lower storage than your PC) without any controversy; Google cannot.

SurprisedTiger•about 3 hours ago

In the only way they know how :-)

rvnx•about 3 hours ago

You can try the model here: https://chromeai.org/ -> Press the left edit button to start a new context.

It's free, multi-language, well tested, respecting privacy (no cloud needed), nothing extra to install. Quite nice actually.

Like what iPhones do, and everybody is ok with it. Chrome is not just a browser, it's a Window (ahem) to the web, almost an operating system considering the wide scope.

Average game is 80 GB, Call of Duty 200 GB+, etc

It's a quite oriented title:

Google Chrome silently installs a 4 GB AI model on your device without consent

The same news can be read as:

Amazing, Chrome now includes a fully offline AI so you don't have to send your secrets to ChatGPT

A proper journalist would have found the middle ground, explained that this is by default, can be made optional and to raise the issue to Google as "Cons: this uses bandwidth and user is not aware of it".

ghurtado•about 3 hours ago
