How to Disable Google's Gemini in Chrome | WIRED
If you use Google's Chrome browser for desktop, there's probably a Gemini Nano AI model running on your computer right now and taking up about 4 GB of space. That's not necessarily a bad thing, but if you didn't know about it and don't want it, there's a way to turn it off.The file started auto-downloading for Chrome users in 2024 after Google built Gemini Nano into the browser. But a report by That Privacy Guy this week and the ensuing reception it received highlighted how unaware many users were—perhaps a result of a flood of AI services and features across the tech industry that have been difficult for users to keep up with.To uninstall the Gemini Nano file, open Chrome on your computer, in the top right corner click the “More” menu represented by three vertical dots, then go to Settings, System, and then toggle “On-device AI” to be off. The Privacy Guy article noted that if you directly uninstall the Gemini Nano file in the directory, Chrome will silently, automatically redownload it the next time the browser reboots.A Google spokesperson tells WIRED that the company started rolling out the On-device AI toggle in February so users can turn off the features if they choose and remove the model. “Once disabled, the model will no longer download or update,” the spokesperson says in a statement. The company added, too, that the system is designed so Gemini Nano “will automatically uninstall if the device is low on resources.”Google built the model into Chrome to enabled on-device AI scam-detection features. It was also aimed at providing a way for developers to integrate AI-related application programming interfaces while keeping data on users' devices when possible and out of the cloud. These features are separate from Chrome's AI Mode, which does not use the local Gemini Nano model.Parisa Tabriz, Chrome's general manager, emphasized in a post on X on Wednesday that integrating Gemini Nano “powers important security capabilities like on-device scam detection and developer APIs without sending your data to the cloud.”Google certainly did announce the Gemini Nano integration into Chrome and discussed it publicly, but for users who simply use Chrome because it is the world's biggest, most recognizable browser and don't necessarily follow every granular update, the lack of an in-your-face notification about a large AI model file sitting and running on your computer may be upsetting.Longtime security and compliance consultant Davi Ottenheimer says that he follo...
Stop Chrome from silently downloading Gemini Nano AI model on Windows ...
Google Chrome automatically downloads the Gemini Nano model when AI features are enabled and used. The model is stored as a 4GB weights.bin file in the “OptGuideOnDeviceModel” folder under %LOCALAPPDATA%. Some users report that the download happens without a clear opt-in prompt and significantly increases disk usage. Deleting or renaming the file is temporary because Chrome automatically restores it. A Registry tweak change can fully prevent Chrome from downloading or restoring the local AI model. On Windows 11 and other supported platforms, Google Chrome can download local AI models automatically without presenting a clear opt-in prompt. If you are trying to keep tighter control over storage usage and background components, this guide explains how to stop that behavior. By default, Chrome pulls down the Gemini Nano model when you interact with AI-powered features such as “Help me write.” The model is stored as a file called weights.bin, which is roughly 4GB in size and located in the %LOCALAPPDATA%\Google\Chrome\User Data\OptGuideOnDeviceModel folder. For many users, the discovery happens only after noticing a sudden spike in disk usage. Although the topic recently resurfaced on social platforms, this behavior is not new. Discussions about the OptGuideOnDeviceModel folder and the large weights.bin file appeared on community forums more than a year ago, with users questioning why Chrome’s disk footprint had grown so dramatically. Those with smaller SSDs often point out that a single 4GB model can feel excessive compared to the browser’s original installation size. The core frustration isn’t only the file’s size but how it arrives. Users repeatedly report that the model downloads silently, without a prominent consent dialog, and that it can appear even if they rarely use AI features. A lot of users see this as a forced opt-in rather than a clearly communicated feature activation. Attempts to remove the file usually prove temporary. Deleting weights.bin, renaming it, or removing the entire “OptGuideOnDeviceModel” folder typically results in Chrome restoring the contents automatically. Even replacing the file with a read-only placeholder may only work until the next browser update. This automatic regeneration has become one of the most cited complaints. The good news is that the behavior can be fully disabled through a policy change in the Registry, preventing Chrome from downloading the on-device AI model in the first place. In this guide, I’ll outline the...
