Chrome's 4GB AI model isn't new, but you're not wrong for being confused

# Chrome's AI Model Isn't New—Google Just Never Told You About It Chrome has been quietly downloading a 4GB AI model to your computer for years to run certain features locally, but Google never clearly explained this to users, which is why people are suddenly noticing it taking up storage space. The confusion is understandable because Google announced these AI features in 2024 without being transparent about the behind-the-scenes download that makes them work. In short: this isn't a new privacy concern, just poor communication from Google about something that's been happening all along.
