How to Disable Google’s Gemini in Chrome
If you use Google’s Chrome browser for desktop, there’s a likelihood that a Google Gemini Nano AI model is running on your computer right now and consuming approximately 4 GB of space. While this isn’t necessarily problematic, if you were unaware of its existence and don’t wish to have it installed, there’s an option to turn it off.
The file began downloading automatically for Chrome users in 2024 after Google integrated Gemini Nano into the browser. However, a report by That Privacy Guy this week and the ensuing reception highlighted how many users were unaware of its presence—perhaps as a result of the tech industry’s flood of AI services and features that have made it difficult to stay informed.
How to Uninstall Gemini Nano
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 proceed to Settings, System, and toggle “On-device AI” off. The Privacy Guy article noted that directly uninstalling the Gemini Nano file in the directory will cause Chrome to silently 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 disable features if they choose and remove the model. “Once disabled, the model will no longer download or update,” the spokesperson states. The company further explains that the system is designed to automatically uninstall Gemini Nano “if the device is low on resources.”
Google’s Intent with Gemini Nano
Google built the model into Chrome to enable on-device AI scam-detection features and provide 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 that integrating Gemini Nano “powers important security capabilities like on-device scam detection and developer APIs without sending your data to the cloud.”
The Impact of Disabling On-device AI
Google certainly announced 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 emphasizes that he follows Chrome updates closely but could have easily missed the Gemini Nano integration. He notes that “an on-device model could be a hidden minefield.” Additionally, Google launched the integration in 2024 but didn’t start rolling out a settings control for users to turn it off until February, indicating that at least initially, the feature wasn’t conceived as something users would interact with.
Considerations and Alternatives
Removing Gemini Nano from Chrome doesn’t necessarily mean you should or that doing so is better for your privacy. Local processing is a more private way to utilize AI capabilities, but if you remove the model, the features Google uses it for—including the AI-enabled scam detection—will cease to function.
The Gemini Nano also serves as a local AI processor for third-party developers, which could have various outcomes when interacting with non-Google web services in the browser. A Google spokesperson tells WIRED that if you turn off On-device AI, “certain security features will not be available, and sites that use the on device APIs will behave differently.”
If neither option seems right, there’s always an alternative: Use a different browser.
Key Takeaways
- The Gemini Nano AI model is running on your computer and consuming approximately 4 GB of space. To disable it, toggle “On-device AI” off in Chrome settings.
- Google started rolling out the On-device AI toggle in February to give users control over this feature, which was initially conceived as something users wouldn’t interact with.
- Disabling On-device AI will stop local processing and may affect interactions with non-Google web services. Gemini Nano is also used by Chrome for third-party developers’ local AI processing.
