Previously, the Google browser drew significant user attention as it repeatedly and automatically downloaded a local AI model of approximately 4GB. This functionality, which has been gradually implemented since 2024, is intended to leverage device-side AI models for tasks such as text composition and phishing website detection. However, this model consumes a considerable amount of users' storage space. Even if users manually deleted it, the browser would automatically redownload it. This behavior sparked concerns among users regarding privacy, storage utilization, and the right to be informed. In response, Google officially stated that the model is primarily used for local security processing to minimize cloud uploads and will automatically uninstall when storage space is low. Google also mentioned that, starting from February 2026, it has incorporated options in the settings to turn off and delete the model. Nevertheless, users have highlighted that the option to disable the feature is concealed and enabled by default, effectively imposing deployment before subsequently seeking authorization. This practice infringes upon users' right to be informed and to make choices. Furthermore, such behavior may contravene privacy regulations, such as the EU's General Data Protection Regulation (GDPR), as it stores information without obtaining explicit user consent.
