Google Chrome AI File Download: How to Delete a 4GB File

Google Chrome AI File Download: A few days ago, reports surfaced that Google Chrome was downloading a 4GB AI model file onto users' devices without their knowledge. This file, named weights.bin , is linked to Google's on-device Gemini Nano AI model, which supports features like scam detection, autofill suggestions, and Help Me Write. This 4GB file is quite large for users struggling with storage constraints. If you don't want this file on your device, it can be easily deleted. Today, we're going to tell you how to delete it and prevent it from downloading again.

First of all know what is inside this file?

According to reports, this file is part of Google's Gemini Nano on-device AI system. Instead of relying on cloud-based servers, Google uses AI models stored on the user's computer to run certain features. This file is stored in Chrome's Application Data folder and appears after updating to a new version of Chrome. Importantly, Chrome does not provide any notifications or alerts to users before downloading it.

Is this file stored on your device?

First, you need to check if this file is stored on your device. To do this, open Google on your MacBook, then open Application Support. From there, open the Chrome section and go to Default. Open the folder named "OptGuideOnDeviceModel." If you see a file named weights.bin in it , it means it has been downloaded to your device. On a Windows laptop, open File Explorer and paste "%LOCALAPPDATA%GoogleChromeUser Data" into it. After entering it, open the folder named "OptGuideOnDeviceModel" in the list that appears. If it contains a file named weights.bin , then this model has been stored on your device.

How to delete?

If you delete this file in the folder, Chrome may download it again. To avoid this, you'll need to disable Chrome's On-Device AI feature. To do this, open the Chrome browser, go to Settings, and then System to turn off On-Device AI. After this, you can delete this file.
