A growing number of users are raising concerns after reports revealed that Google Chrome may automatically download a large AI model onto supported devices without providing a clear notification. The development has sparked discussions around privacy, storage usage, and user control as technology companies continue expanding on-device artificial intelligence capabilities.
At the centre of the discussion is Gemini Nano, Google’s compact AI model designed to run directly on a device rather than relying entirely on cloud-based processing. The model powers several AI-driven Chrome features, including writing assistance, scam detection, text suggestions, and other on-device functions.
According to reports, Gemini Nano can be automatically downloaded on eligible Windows, macOS, and Linux systems. The AI model is stored as a file known as “weights.bin” within Chrome’s system folders and occupies approximately 4GB of storage space. Concerns have emerged because the download may occur without an explicit consent request or a clear notification to users.
The issue has also drawn attention to storage and bandwidth consumption. Some users reportedly became aware of the download only after noticing a reduction in available storage on their devices. Reports further indicate that deleting the file manually may not be a permanent solution, as Chrome could automatically download it again if related AI features remain enabled.
For users who do not wish to keep the AI model on their devices, reports suggest that Chrome’s on-device AI functionality can be disabled through browser settings. Turning off the “On-device AI” option within Chrome’s System settings is said to remove the file and prevent local AI processing. However, doing so may also disable AI-powered features such as writing assistance and scam detection.
The development reflects the broader industry trend of bringing AI capabilities directly onto consumer devices. While on-device AI can offer benefits such as faster performance and local data processing, the rollout has also reignited discussions around transparency, user awareness, storage management, and the level of control users have over software features installed on their devices.
