"Silently installs" is misleading. They are including a file in the package which is presumably related to the functionality of the software. I don't use chrome for a long list of reasons but it is not standard or expected to get consent for that.

Look at how many headlines indicated that something is silently happening. It's a weird trend at the moment.

They've been consuming 15+ years of anti-Mozilla rants anytime it or Firefox are mentioned online. It's how you get things like "Browser monocultures are an issue, so don't use Chrome (Blink), use Brave (Chromium (Blink)) instead!" said in earnest.

If Mozilla fired its CEO for a private political donation from 10 years earlier, it will not hesitate to do much worse to its users. Mozilla isn’t on the good side here. He’s the founder of Brave, by the way.

Then what is your definition of "installing" exactly? Are you going to split hairs about it not being a separate program being installed and running in the background, but weights being used by code that is run inside the browser? Because honestly, I don't think there's any significant difference from the user's perspective here. Other than the fact that doing the latter bypasses the need to get permission to install a new program. Which makes it an even worse violation, in a way, since it undermines the trust that the browser as a platform is just a browser.

A 4 GiB model has nothing to do with the functionality of a web browser. It is something forced on users without their consent.

Of course that's what we get for giving the benefit of doubt to the company that insisted on learning the wrong things from the Google Buzz fiasco.

Those two (and more) exist in chrome://flags in Chrome 147. I'm disabling them now, with the expectation that will prevent the new default. One option I'm leaving as default is "Use LiteRT-LM runtime for on-device model service inference." Any comment on that?

I'm on Chrome 147 too and disabled: "optimization-guide-on-device-model" - Enables optimization guide on device "prompt-api-for-gemini-nano" - Prompt API for Gemini Nano - Prompt API for Gemini Nano with Multimodal Input and deleted weights.bin and the 2025.x folder in "OptGuideOnDeviceModel" Will report if Chrome 148 downloads the model again.

If you touch those files into existence and chown to root and chmod to 0, it shouldn’t be able to ever overwrite them right?

There is, however, precedent for software alerting/asking the user to install “extras” or utility packs and showing the disk size that content will take up and even allowing the user to choose a location to store such things. Creative software does this all the time.

There’s nothing stopping Google Chrome from doing something similar except, I suspect, Google knows or feels it will result in many fewer installs of its bloatware.

It's based on Gemma 3n, and it's not the best. I find it works fine for simple classification, translation, interpretation of images & audio. It can write longer prose, but it's pretty bad. It can also write text in the format of a JSON schema or regexp for anything you might want to do with structured data.

I wonder why they’re using Gemma 3 and not Gemma 4?

So that the big news in non-tech news sites will be the update. Thus ensuring that this is received in a positive light.

I have no idea but when I mention Firefox my colleagues under 35 or so literally think I'm joking.

They've been consuming 15+ years of anti-Mozilla rants anytime it or Firefox are mentioned online. It's how you get things like "Browser monocultures are an issue, so don't use Chrome (Blink), use Brave (Chromium (Blink)) instead!" said in earnest.

Or simply they haven't heard much about it at all, don't care, and chalk it up to OP being some sort of an odd hipster.

Man, so many things could be better if people cared.

It's not a very good small model to be honest. That said, you might be surprised to learn that some of the models from 3b-9b could probably replace 80% of the things nonvibe coders use chatgpt for. Its a good idea to run small models locally if your computer can host them for privacy and cash saving reasons. But how can you trust Google to autoinstall one on your machine in 2026? I just couldn't do it.

Sure, local models good and yes, there's no way we can trust Google. We can be positive the entire motivation of Chrome is user behavior surveillance. There's not a nano-chance in all the multiverses that Chrome model is doing anything privately. They've gone to extraordinary length to accomplish this. It's not for free.

I don't trust them either, but the same Google makes Gemma 4 available to run as locally and privately as you want, and those models are pretty amazing for their size.

yeah, should work. Will try readonly on windows too.

Now I can't see it anymore, but shouldn't the model be under chrome://on-device-internals/ -> model-status?

Maybe you can uninstall there too.
