• Chrome downloads a 4 GB AI model (Gemini Nano) for on-device processing, which it has been doing for two years, but users are only now noticing.
  • Google has not rolled out the model universally; installation depends on hardware, account features, and visited websites.
  • Users can disable local AI features in Chrome settings, after which the model is deleted.
  • Google removed the stipulation that the model does not send data to its servers, but claims processing remains entirely on-device.
  • If a website uses Chrome’s AI API, input and output data may end up on that site’s servers, including Google’s.
