PANews reported on May 6th that, according to Tom's Hardware, security researcher Alexander Hanff pointed out that Google Chrome silently downloads approximately 4GB of local AI model file "weights.bin" to compatible devices without explicitly informing or obtaining user consent. This file, based on the Gemini Nano, is used for local AI functions within the browser. Hanff stated that even if the user manually deletes it, the file will still be re-downloaded in the background unless the experimental feature is disabled or Chrome is uninstalled. He believes this behavior may violate the EU ePrivacy Directive and GDPR requirements regarding data storage and transparency on user devices, and will incur additional bandwidth costs and significant energy consumption globally.
