Overview
- Google updated its AICore support page to say storage use can spike during background AI model updates.
- It keeps both the current and new model on the device for up to three days to enable a quick rollback if the update fails.
- Once the new model is confirmed stable, AICore deletes the older files and frees the extra space automatically.
- Users have reported AICore using about 7GB to 11GB, which can strain phones with 128GB of storage more than larger models.
- AICore powers on‑device Gemini Nano features like smart replies, scam detection, and offline transcription, so turning it off would disable many of those tools, even as reviewers urge Google to add controls to manage the temporary storage load.
