How to Disable Google’s Gemini in Chrome

If you use Google’s Chrome browser for desktop, there’s a small AI model called Gemini Nano running on your computer right now. This doesn’t necessarily mean it’s 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 integrated Gemini Nano into the browser. However, a report by That Privacy Guy this week and the ensuing reception 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.

Disabling 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 go to Settings, System, and finally toggle “On-device AI” to be off.
  • Note that if you directly uninstall the Gemini Nano file in the directory, Chrome will silently, automatically redownload it the next time the browser reboots. This is why it’s important to ensure the setting is turned off before a reboot.

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. They state, “Once disabled, the model will no longer download or update.” The company also added that the system is designed such that “Gemini Nano will automatically uninstall if the device is low on resources.”

What Gemini Nano Does

Google built the model into Chrome to enable 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.”

The Discomfort of Knowing

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 follows Chrome updates closely but could have easily missed the Gemini Nano integration. He notes, “An on-device model could be a hidden minefield.” And the fact that Google launched the integration in 2024 but didn’t start rolling out a settings control for users to turn it off until February shows that, at least initially, the feature wasn’t conceived as something that users would interact with.

Disabling Gemini Nano: A Consideration

  • Local processing is a more private way to utilize AI capabilities. If you remove the model, the features Google uses it for—including the AI-enabled scam detection—will cease to function.
  • The fact that Gemini Nano is also used by Chrome to enable local AI processing for third-party developers means 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.”

Of course, if neither option seems right, there’s always an alternative: Use a different browser.

Key Takeaways

  • The Gemini Nano AI model is running on many Chrome users’ computers without their knowledge and can be disabled through settings.
  • Removing the Gemini Nano file may affect Google’s security features, as well as third-party developers’ services in the browser.
  • For those who want to keep local processing for AI capabilities, there’s a risk that some security features will not be available if On-device AI is disabled.
