GoKawiilGoogle Chrome could be taking up some extra storage space on your device. Based on reports from earlier this month, the browser has been automatically downloading a 4GB AI model onto some users' hard drives without their permission. This isn't the first time Google has discreetly interfered with users' devices, and privacy advocates say the practice may violate data laws.
The mysterious file in question is Gemini Nano, an AI model that runs on devices such as smartphones and laptops rather than in the cloud. According to Alexander Hanff, a Swedish computer scientist and lawyer known as That Privacy Guy, it's been installed on some Chrome browsers without permission. You won't know when it's been downloaded onto your device, either.
Hanff said Gemini Nano will only be installed if the device meets the hardware requirements. It's still unknown how many people have gotten the install.
Gemini Nano performs tasks such as detecting scam phone calls, helping you write text messages, summarizing recordings and analyzing Pixel phone screenshots. It's not to be confused with the AI Mode pill in the address bar. If you use AI Mode, your queries are routed to Google Gemini servers, not to Gemini Nano.
A Google spokesperson told CNET that Gemini Nano will automatically uninstall if the device doesn't have enough resources, such as processing power, RAM memory, storage space or network bandwidth.
"In February, we began rolling out the ability for users to easily turn off and remove the model directly in Chrome settings," the spokesperson said. "Once disabled, the model will no longer download or update."
Google gives more information about on-device generative AI models in Chrome on this web page.
How to get rid of the AI model
If you want to remove the 4GB AI model from your device, first check whether it's installed.
Hanff said Chrome users will not know they have Gemini Nano unless they search for it, because "Chrome did not ask" and "Chrome does not surface it."
