How to Disable Gemini AI in Chrome

▼ Summary
– Chrome’s desktop browser includes a Gemini Nano AI model that takes up about 4 GB of space, which was auto-downloaded starting in 2024.
– Users can disable Gemini Nano by going to Chrome Settings, then System, and toggling “On-device AI” off; uninstalling the file directly causes Chrome to redownload it.
– Google says the On-device AI toggle, rolled out in February, lets users turn off features and remove the model, which will also auto-uninstall if the device is low on resources.
– Gemini Nano enables on-device AI scam detection and developer APIs, keeping data local, but disabling it stops these security features and may affect web services.
– Many users were unaware of the model, and the lack of a clear notification about the large file has caused concern, though local processing offers more private AI use.
If you’re running Google’s Chrome browser on a desktop computer, there’s a strong chance a Gemini Nano AI model is quietly occupying roughly 4 GB of storage space right now. That’s not automatically a problem, but if you were unaware of its presence and prefer not to keep it, you have the ability to remove it.
This file began auto-downloading for Chrome users in 2024 after Google embedded Gemini Nano directly into the browser. A recent report from That Privacy Guy, along with the wave of attention it generated, revealed just how many users were caught off guard. That surprise likely stems from the relentless surge of AI tools and features across the tech landscape, making it tough for anyone to track every change.
To delete the Gemini Nano file, launch Chrome on your computer, click the three vertical dots in the top-right corner to open the “More” menu, then navigate to Settings, System, and toggle “On-device AI” to off. The Privacy Guy article cautioned that simply deleting the Gemini Nano file from its directory won’t stick,Chrome will silently re-download it the next time the browser restarts.
A Google spokesperson confirmed to WIRED that the company began rolling out the On-device AI toggle in February, giving users the option to disable these features and remove the model. “Once disabled, the model will no longer download or update,” the spokesperson stated. Google also noted that the system is built so Gemini Nano “will automatically uninstall if the device is low on resources.”
Google integrated the model into Chrome to support on-device AI scam-detection features and to give developers a way to use AI-related application programming interfaces while keeping data on users’ devices rather than sending it to the cloud. These capabilities are distinct from Chrome’s AI Mode, which does not rely on the local Gemini Nano model.
Parisa Tabriz, Chrome’s general manager, explained in a post on X on Wednesday that embedding Gemini Nano “powers important security capabilities like on-device scam detection and developer APIs without sending your data to the cloud.”
While Google did announce the Gemini Nano integration and discuss it publicly, many users simply rely on Chrome because it’s the world’s largest and most recognizable browser, without closely following every update. For them, the lack of an obvious notification about a large AI model running on their computer could feel unsettling.
Longtime security and compliance consultant Davi Ottenheimer noted that even though he tracks Chrome updates carefully, he could have easily overlooked the Gemini Nano integration. “An on-device model could be a hidden minefield,” he warned. The fact that Google launched the integration in 2024 but didn’t introduce a settings toggle for users to disable it until February suggests the feature wasn’t originally designed with direct user interaction in mind.
Removing Gemini Nano from Chrome isn’t necessarily the right move for everyone, and it doesn’t automatically improve your privacy.
Local processing offers a more private way to tap into AI capabilities. If you delete the model, the features Google uses it for,including AI-enabled scam detection,will stop working. But because Gemini Nano also enables local AI processing for third-party developers, blocking it could produce varying results when you interact with non-Google web services in the browser. A Google spokesperson told WIRED that turning off On-device AI means “certain security features will not be available, and sites that use the on device APIs will behave differently.”
If neither keeping nor removing the model feels right, there’s always a simpler alternative: Switch to a different browser.
