Chrome, Edge Now Require 20GB Disk Space for On-Device AI Models

Google Chrome and Microsoft Edge are quietly preparing to download large on-device AI models, and that shift will consume significant hard drive space on your computer. The new requirements mean users need approximately 20GB of free disk space available to initiate the download process. This change matters because it forces a reevaluation of storage management for anyone running these browsers on devices with limited capacity.

Browser updates mandate significant storage and GPU upgrades for local AI

The update targets the core browser engines used by millions of Windows and macOS users. Microsoft Edge introduces stricter hardware filters, requiring a GPU with at least 5.5GB of VRAM to qualify for the feature. Google Chrome keeps the process simpler but still mandates an unmetered network connection to prevent unexpected data usage.

Technical specifications for the download are precise and non-negotiable for eligibility. Edge users must have Windows 10 or 11, or macOS 13.3 or later, installed on their machines. The browser also enforces a hard limit by automatically deleting the AI model if available storage drops below 10GB. Chrome users can manually intervene by navigating to Settings > System and disabling the on-device AI feature entirely.

The 20GB figure represents a prerequisite for the download rather than the final size of the AI model itself. Both browsers require an unmetered network connection to ensure the large files transfer without consuming mobile data plans. These requirements reflect the growing computational demands of local AI inference within standard web browsers.
