Chrome quietly ships 4GB on-device AI model Gemini Nano, prompting privacy concerns
Google Chrome reportedly rolled out a 4GB on-device AI model called Gemini Nano to eligible desktops between late April and early May 2026 without user consent or a prompt. The model runs locally (not via Google servers) and can be removed by toggling off On-device AI or uninstalling Chrome, with specific steps for Mac and Windows to detect and delete the files. Google says the model will auto-uninstall if resources are insufficient and has introduced a setting to disable or remove it; privacy advocates warn the rollout could violate GDPR and raise concerns about transparency and user control.
