Is Chrome’s 4GB “weights.bin” file spyware? The truth behind the viral warnings

• Users noticed Google Chrome silently downloading a 4GB file called “weights.bin” in the background, sparking privacy concerns.
• This file actually helps run Gemini Nano on-device, improving privacy by processing AI requests locally rather than sending data to the cloud.
• Users frustrated by the storage hit can stop the downloads by disabling specific Chrome flags before deleting the model folder.
