The discovery that Google Chrome reportedly downloaded a massive 4GB AI model in the background without users’ consent has prompted a myriad of negative comments. The conversation about the unexpected download began when security researcher Alexander Hanff, also known as “The Privacy Guy,” revealed in a blog post that Chrome could do this and detailed the potential legal and environmental implications.
Hanff’s post also noted that this is not new, and many users may already have the file downloaded without being aware of its presence. According to the blog, reports of the file date back more than a year, when users noticed that Chrome was suddenly using more storage than usual. The report states that the file, named weights.bin, may still be present on some systems.
Hanff explained that the file contains the weights of Chrome’s Gemini-based AI model, which powers features such as “Help Me Write,” scam detection, and other AI tools. The download is triggered when these AI features are enabled; otherwise, it remains dormant.
Google has provided guidance on its help page for turning off these features. The company also states, “If you delete on-device AI models, only features that rely on them will be unavailable.”
However, manually deleting the file may prompt Chrome to download it again. With billions of devices potentially silently downloading 4GB of data, Chrome’s behavior has raised concerns among users and questions about its legal and environmental impact.
