chrome huge file weights.bin - can it be deleted
Chrome has a huge file inside AppData\Local\Google\Chrome\User Data\OptGuideOnDeviceModel\2025.8.8.1141\weights.bin
The size of the file weights.bin is 4.0 GB
I want to delete this file. Will it prevent chrome from functioning? What is it used for?

It's an AI model, reportedly Gemini Nano.
I haven't tried this (having moved away from Chrome before the AI-in-everything craze), but users have suggested that it can be deleted if you are willing to restart the browser afterwards.
However, unless you set your computer's policy for Chrome not to use AI, the file will be downloaded again each time Chrome is updated.
- Mac:
defaults write ~/Library/Preferences/com.google.Chrome.plist GenAILocalFoundationalModelSettings -int 1 - Windows: Set
