Chrome Is Dropping Its Privacy Promise for On-Device AI — What You Need to Know

If you use Chrome, you may have noticed something new eating up disk space or making your browser behave differently. Over the past few days, multiple reports have confirmed that Google is quietly installing a 4GB AI model on users’ computers — and that Chrome’s earlier privacy promise about this feature has been removed. Here’s what changed, why it matters, and what you can do about it.

What Happened

Earlier this month, Google introduced an on-device AI feature in Chrome that is designed to run language models locally. The idea sounds good on paper: faster processing, no cloud round trip, better privacy. But two things are raising eyebrows.

First, the privacy promise disappeared. When the feature was first announced, Chrome’s help pages stated that the on-device AI “does not send any data to Google” and that all processing stays local. According to a report by Decrypt (May 7, 2026), Google has since removed that language. The updated text no longer assures users that data stays on the device, which implies — at least in principle — that some information might be sent back.

Second, Chrome is installing the AI model automatically. Even if you haven’t opted in, Chrome may download a 4GB model to your computer in the background. Yahoo Tech reported on May 6 that users who manually deleted the model found it reappearing after a browser update or restart. This behavior has frustrated people who would rather not use the feature.

Google also announced that it found a way to make local AI up to three times faster without new hardware, suggesting the company is pushing hard to make on-device AI a core part of Chrome’s future.

Why It Matters

For average users, the main concern is control. You might not want a 4GB model on your hard drive — especially if you’re on a laptop with limited storage. The bigger issue is trust. Google initially positioned on-device AI as a privacy-friendly alternative to cloud AI. Removing the “no data sent” promise raises questions about what exactly the model is doing and whether it phones home.

At this point, it’s unclear whether Google intends to collect usage data or telemetry. The removal of the explicit promise doesn’t prove that data is being sent, but it does remove a layer of reassurance that users relied on. That’s a meaningful change for anyone who values predictability in privacy policies.

There’s also the bandwidth and storage cost. A 4GB download might be fine on a fast connection, but if Chrome is doing this silently — and restoring the model after deletion — that feels intrusive. Users should be able to decide what runs on their machines.

What Readers Can Do

If you want to keep the AI off your system and avoid unexpected downloads, here are the steps you can take. These instructions will work in current versions of Chrome (for Windows, macOS, and Linux).

1. Check your Chrome version.
Go to chrome://settings/help and make sure you’re up to date. The relevant flags may vary slightly between versions.

2. Disable the on-device AI feature.
Type chrome://flags in the address bar. Search for “on-device AI” or “local model.” You’ll likely see a flag called “On-Device AI” or “Enable local language model.” Set it to Disabled. Restart Chrome.

Alternatively, go to chrome://settings/ai — if the feature is available — and toggle it off.

3. Remove the downloaded model (if it’s already there).
The model files are stored in Chrome’s user data directory. On Windows, that’s usually in %LOCALAPPDATA%\Google\Chrome\User Data\OnDeviceAI. On macOS, ~/Library/Application Support/Google/Chrome/OnDeviceAI. On Linux, ~/.config/google-chrome/OnDeviceAI. Delete the entire folder. Note that Chrome may redownload it if you don’t also disable the flag.

4. Prevent automatic redownload.
After deleting the folder, restart Chrome with the flag disabled. If you see the model reappear, check that the flag is still set to Disabled after updates. Occasionally, Chrome resets flags. You can also add the --disable-on-device-ai command-line switch to your Chrome shortcut for extra assurance.

5. Monitor future updates.
Keep an eye on Chrome’s release notes. If Google clarifies its data handling policy, you can make an informed choice. For now, the safest route is to opt out.

Bottom Line

Google’s pivot on the privacy promise is real, and the automatic installation of a large AI model is a practical concern for many users. At the moment, you still have the ability to turn it off. If you value knowing exactly what your browser does with your data, now is a good time to check your settings. The feature may become more integrated over time, so understanding how to control it today gives you a head start.
