Chrome Silently Downloads 4GB Gemini Nano Model on PCs and Macs
6 articles · Updated · MUO - MakeUseOf · May 24
A 4GB file called weights.bin is being downloaded by Chrome onto some Windows and macOS devices without a permission prompt, adding Google’s Gemini Nano on-device AI model to local storage.
Google uses the model to run AI features locally — including text generation, article summaries and scam warnings — which can improve privacy by keeping some requests off its servers and cut cloud-computing costs.
The download does not hit every user: devices must meet hardware requirements and have at least 22GB of free space before Chrome pulls the model.
Users can delete the file, but Chrome will download it again unless on-device AI is turned off in Settings; disabling it removes the model but also shuts off related AI and some security features.
The episode highlights a broader trade-off in browsers: heavier local AI tools can reduce server reliance and support new features, but they also consume gigabytes of storage without clear upfront consent.
If Chrome's on-device AI is for privacy, why does its silent 4GB installation violate European privacy laws?
Does Chrome's AI force a choice: sacrifice 4GB of storage or give up modern browser security tools?
