Google Chrome silently installs a 4 GB AI model on your device without consent(www.thatprivacyguy.com)

> The pattern was: install on user launch of product A, write configuration into the user's installs of products B, C, D, E, F, G, H without asking. Reach across vendor trust boundaries. No consent dialog. No opt-out UI. Re-installs itself if the user removes it manually, every time Claude Desktop is launched.

God, I'm SICK of this AI slop style. After ingesting terabytes of pirated books you'd expect a little bit more variety in it's writing.

Like 2/3 posts on HN now have this "No X. No Y. No Z." pattern. It's one of strong signals for me that the author didn't bother and just copy pasted their LLM's output as is. And the LLM mostly likely was pointed at some other resource to write the article, and I'd rather read the original. I think HN needs a policy to replace AI slop articles with the original articles/announcements etc. once detected, and technically the guidelines already cover it: "Please submit the original source. If a post reports on something found on another site, submit the latter."

>After ingesting terabytes of pirated books you'd expect a little bit more variety in it's writing.

I think it's the result of post-training. The original base model most likely had a less slopy style. This style is what AI companies think is a good style (they specifically train for it).

One upside to this is that it doesn't use Gemma and instead uses Gemini. So at least for Gemini Nano (apparently called XS internally by Google) it means that the weights are now de facto open and you no longer need a current Android phone to get the latest and best model in this class. This also makes it the only open American frontier-level model right now.

Can you provide any sources for that? I'd like to learn more about this open frontier model.
sigmoid10 3 hours ago||
Sources for what? The pareto frontier of LLMs? How Google is pretty much on the line with most of their LLM products? Or this particular model? For the first two you need to look for size/cost vs. accuracy charts. There are tons of them floating around. For the latter there is not much official info except what you can infer by analyzing the weights.bin file that Chrome downloads. But it does mention Gemini in there, so it seems pretty obvious that it is from their proprietary line of models.

Just because it's called Gemini doesn't mean that it's somehow automatically as comparable with the frontier of small models as well, does it?
sigmoid10 3 hours ago||
All Gemini models sit around the frontier, especially if you go to smaller sizes. Google is actually more invested into efficiency than size unlike some of the other big providers.
lxgr 3 hours ago||
Do you have any benchmark details on the on-device Gemini models? I haven't found a lot of public information on these.

Sources for your claim that the model being downloaded to Android/Chrome is Gemini instead of Gemma. Other than downloading the bin file myself and analyzing it lol.

How about Google itself?

>With the Prompt API, you can send natural language requests to Gemini Nano in the browser.

HumanOstrich 3 hours ago|||
Thanks. Looks like the current Gemini Nano is actually a separate model with the Gemma 3n architecture that has been distilled from Gemini 2.5 Flash[1].

Also, the next version of Gemini Nano will be based directly on Gemma 4 (so not distilled, not Gemini at all except for the name)[2].

So no, it's not a frontier model. Those don't run on your phone or in your browser.

Oh, now I see your problem. You confused the pareto frontier with the pure scale frontier. They are very much not the same.

Also, distillation is how most of these smaller models are made from the biggest models. That process largely defines the frontier along most of the curve.

Better not, it's too buggy and sluggish, it's more in a beta stage on desktop. I've been using it for the last year but not anymore.

that's a willing act - you are actively asking npm to download something, and accepting it might be terrible for you.

Here chrome is just installing things behind your back, whether you really want it or not.

Never use “npm install”, only “npm ci”. Using “npm install” is a willing act to run fresh exploits.

> 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.

Environmental analysis for operations? Not a fan of thinking in such terms.

> For users on capped mobile data plans, particularly in regions where smartphone-as-only-internet is dominant (much of Africa, much of South and Southeast Asia, most of Latin America), 4 GB of unrequested download is on the order of a month's data allowance, vapourised by Chrome on the user's behalf. Google has not, to my knowledge, published any analysis of the welfare impact of this on the populations whose internet access is metered.

THIS is a valid concern. Otherwise I'm not buying into "ask for consent because of dependency X". Users don't like questions/consents.

However OS (at least windows) has an way to set network connection as a metered so software can make informed decisions. Also Android has "Data Saver" function which should also be honored by software.

Why not? It's about 60 000 London - New York City flights by the way (https://www.theguardian.com/environment/ng-interactive/2019/...). And what's the benefit again?

The "normal sustainable progress" has already pushed us to the brink of extinction. AI is rapidly accelerating our resource use, with nothing good to show for it.
lxgr 3 hours ago||
How exactly are we "on the brink of extinction"? ("We" as in humans; many other species are obviously not as lucky.)

We are probably on the brink of very bad consequences for a signification fraction of all humans (up to and including all of them, to some extent), which is a huge problem that needs to be addressed.

But what do you gain by incorrectly labeling that as "extinction"? Because you do definitely lose credibility for it, similarly to everybody using hyperbolic language such as "boiling the oceans" etc.

If it's emissions they worry about, then it's anything emitting.

Are they against washing machines too? Or are they just grandfathered in?

This is literally why the EU mandates appliance energy efficiency.

It's never a binary thing. "Is using energy good or bad?" is a stupid question which can only provide stupid answers. It has to be placed in the context of whether it's proportionate to benefit.

Things which burn a lot of energy for little benefit - and in the case of AI, often negative benefit - end up more towards the "bad".

Are we back to magic water and magic soil? Does the energy have some morality attached to it?

The emissions per kWh of energy used in providing internet downloads probably is similar to that per kWh of energy used for washing clothes.

You're not seriously trying to explain that a kWh is equal to a kWh. Why not cut the crap? Are you trying to say washing clothes is of equal importance to convenience features in a browser, given that we can use each clean kWh only once? I can't tell what you truly mean like this

Our planet is literally dying.

The oceans are boiling [0], marine life is dying [1]. Land close to the water will be land under water soon [2]. The ice caps are melting and setting free all sorts of diseases. [3]

Large parts of our planet on fire all the time now, here's one from Australia from this year [4], but I'm sure you've read about wildfires in Australia last year, California every year, Greece last year etc etc.

What you're proposing is nothing short of a death cult. It's either degrowth or we all die, sacrificed at the altar of capitalism.

Have you ever made a decision to NOT download something, turn on your computer, experiment, etc based on your perceived impact on the planet?

I mean this should (and is) be tackled at the source: 0/low emission energy generation and not consumer having to think about these decisions. Sustainable data centers using renewables etc. But not that the companies should associate/evaluate/consider bytes downloaded with environmental impact.

>not consumer having to think about these decisions

Consumers vote and advocate for what they want and don't want. There are many who say it's not an individual problem and should be dealt with broadly through regulation, then also oppose any attempts at regulation.

Until we're at that point though, the 'winners' in this market society (that wield unimaginable amounts of money = resources) such as Google could certainly think about consequences of their choices. And they usually do to some extent, I'm not saying they don't, just that electric supply and demand has two sides to it

Why do you attribute to capitalism an issue that is much more fundamental than it? People want more stuff and better lives, it's as simple as that. Even hunger/gatherer societies brought themselves to extinction multiple times in the past, and I doubt the USSR would have fared better against climate change.

Technological progress is also societal progress. If we embraced degrowth in the 1800's (there was a ton of pollution back then, and a Malthusian belief in disaster!) we might not see slavery being abolished or women being able to vote.

Not everyone wants this at the cost of others. It's not as simple as that / not a necessary consequence of our desire to find clever solutions to solve everyday inconveniences

Because capitalism ties together better lives an ideological belief in unbounded growth.

Will people's lives really be better once they're drowning or choking on wildfire smoke? But hey, at least they had cheap junk!

It's possible to have better lives as well as societal progress without endless growth. Technological progress, too, doesn't have to mean burning our oceans. We just gotta actually think about the costs and consequences of our actions.

Not every technological development is inherently good. Sometimes the cost is not worth the result. I posit the cost of AI so far has been astronomical, higher than anything else in living memory. The results on the other hand have been rather middling.

This is my issue. A cost/benefit analysis, not a strict no to progress.

I know it takes extra steps to make Android perform OS or app updates over LTE. I doubt it's downloading a 4GB model over LTE unless the user has chosen to perform updates over LTE.

Unfortunately, that automation is unreliable. It doesn't work across operating systems - Windows laptops won't enable data-saver mode when connected to iPhones and macOS laptops won't when connected to Android phones, and neither will enable it when connected to, say, public transport wifi.

And even if the OS has the information, websites can't reliably use it either. Firefox and Safari both don't implement the NetworkInformation API [1].
