| # CallMe | |
| The on-device models the **CallMe AI** iPhone app downloads with **Download All Three** | |
| (Settings → Models). Each folder is one component of the voice stack. The app fetches only | |
| the files it needs, checks each large file against its SHA-256, and resumes interrupted | |
| downloads. | |
