Google Chrome auto-installs 4GB AI model without consent

Google Chrome has begun silently deploying a 4GB on-device AI model to user machines without explicit opt-in consent, surfacing in local storage directories tied to Chrome's built-in AI features. This raises immediate red flags for enterprise security teams, privacy-conscious developers, and IT administrators managing controlled environments. Unlike opt-in on-device models such as Apple's on-device ML frameworks or Mozilla's locally-scoped experiments, Chrome's silent installation bypasses user agency entirely. Organizations with strict data governance, limited disk quotas, or air-gapped systems should audit Chrome deployments immediately.
