All of Google's products have been getting more AI features, including Chrome, which now offers split-screen Gemini chatbot support, the ability to automate web browsing, and more. Some desktop Chrome users have also noted that the browser appears to suddenly want more storage space for AI. This is true—Chrome does download a 4GB AI model for on-device processing. It's been doing that for years, though.
Google hasn't actually changed anything about Chrome's on-device AI, but the confusion is understandable, as the company has done a poor job of explaining what it's doing and why. This is, unfortunately, par for the course with Google's AI efforts.
Just this week, someone noticed that Chrome had downloaded a 4GB Gemini Nano model and inferred from its sudden appearance that Google was deploying that AI on all Chrome installs right now. That's not exactly true. Google announced in 2024 that it would begin adding local AI capabilities to Chrome, powering features like Help Me Write, tab organization, and scam detection.
