Google has detailed official hardware and system requirements for integrating the Gemini Nano AI model locally within the Chrome browser. While intended to enable on-device artificial intelligence processing, the update introduces steep local storage demands.
High Storage Thresholds
According to official documentation, Chrome requires 20 GB of free disk space to initiate downloading the generative AI models.
- Post-Installation Footprint: The actual AI models consume approximately 4 GB of SSD space once installed.
- Minimum Requirement: The browser actively blocks the initial download unless the full 20 GB buffer is available.
- Base Comparison: A standard Chrome installation utilizes roughly 1.5 GB of storage, making the new threshold over ten times the browser’s baseline footprint.
This requirement poses a significant storage constraint for entry-level laptops equipped with 128 GB or 256 GB SSDs.
Hardware Detection and Disabling On-Device AI
Alongside storage space, Google specifies that devices must have an unmetered internet connection and sufficient hardware performance. While exact RAM and CPU core specifications were not disclosed, Chrome will automatically assess system performance before attempting to fetch the files.
For users seeking to save disk space or prevent automatic downloads, deleting local model files manually is ineffective, as Chrome will automatically re-download them. To permanently remove the models and regain storage space, users must adjust their browser settings:

- Turn On-device AI on or off.
Deactivating this setting safely uninstalls the local AI models and blocks future background downloads.
