- The weights.bin file corresponds to Gemini Nano, a local AI model that Google installs without prior notice, occupying several gigabytes.
- To remove it, you can disable the GenAI option in the System menu or modify the optimization flags in the browser.
- There are methods to clean Google search results using the Web filter or by setting up a custom search engine with the parameter udm=14.
I'm sure it's happened to you: you suddenly notice an inexplicable drop in your hard drive space, and upon investigating, you stumble upon a file called weights.bin that weighs several gigabytes. Many people's first reaction has been to panic, thinking it's a Trojan or some kind of spyware, but don't worry, it's nothing of the sort. It's Gemini Nano , the compact artificial intelligence that Google has decided to shoehorn into Chrome to make the browser "smarter" without always relying on the cloud.
What's raised concerns isn't the tool itself, but rather that Google rolled it out without notifying anyone , downloading the model in the background while you were browsing peacefully. This AI is primarily used to detect scams in real time and provide developers with tools to create local features, but the fact that it takes up so much space and installs itself without permission has left more than a few users quite suspicious.
How to get rid of the weights.bin file and disable AI?
If you want to recover those gigabytes of storage, there are several ways depending on your Chrome version, as Google is gradually releasing these options. The simplest way is to go to Settings , navigate to System , and find the option called "GenAI on device" to disable it. Turning this off will not only stop the device from updating, but the browser should also delete its installed files.
For more technical users or those who don't see the previous option in their settings, there's an alternative using Chrome flags . Type chrome://flags in the address bar and search for the terms #optimization-guide-on-device-model and #prompt-api-for-gemini-nano . If you can change them, set them to "Disabled" and restart the browser. However, keep in mind that in some versions these options may appear unavailable, requiring more drastic methods.
In professional or corporate environments, management is different. There's a policy called GenAILocalFoundationalModelSettings that allows system administrators to block these downloads at the registry level in Windows or macOS. If this policy is disabled, the system blocks any future downloads and automatically removes any models already present on the computer, saving the user from having to navigate through menus.
Another area where AI has taken root is in Chrome's "enhanced protection ." This feature analyzes downloads and dangerous sites in real time, but to function optimally, it sometimes requires browsing data to be sent to Google's servers. While this protection is usually disabled by default, if you choose to enable it in Privacy and security > Security , you could be enabling generative AI processes that consume local resources.
It's important to know that manually deleting the weights.bin file doesn't break the browser , although Chrome will likely try to download it again in the next update if you haven't disabled the feature at the root level. Google's trend is clear: they want AI to be local to reduce latency, but they've done so at the expense of transparency for the end user.
How to clean up AI search results
Aside from disk space, many people are fed up with AI Overviews —those AI-generated summaries that appear at the top of Google and sometimes push the actual results down. While there's no global "off" button, there are some very effective tricks. The quickest is to click on the "Web" tab after performing a search; this filters everything and leaves you with only the traditional links, eliminating the AI noise.
If you want something more permanent, you can create a custom search engine in Chrome's settings. By setting up a new search with the URL https://www.google.com/search?q=%s&udm=14 , you force Google to always show you the classic web version. Another simpler alternative is to add the -ai command to the end of your searches, although this method is less reliable and doesn't always guarantee that the summary will disappear completely.
In short, Google has intrusively integrated Gemini Nano and other AI features, impacting both PC storage with the weights.bin file and the search experience. To regain control, you need to navigate through system settings, adjust browser flags, or use specific search filters to return to a cleaner and more private browsing experience.
