Open the configuration UI after installation:

QVAC starts with the compact qwen3-600m model. Its first download can take several minutes; later starts reuse the persistent model cache.
- Open Models in the configuration UI.
- Select Browse library.
- Search or filter the installed QVAC catalogue and add the models you want.
- Review which models are defaults or preload at startup.
- Select Save & reload.
Models that do not preload are loaded when first requested. This helps avoid filling the node's memory when several models are configured. Advanced users can add a model URL or local path, edit the complete JSON, or import an existing qvac.config.json from the same page.
Use the API key chosen during installation as a Bearer token. Omit the Authorization header if no key was configured.

}'The UI remains available while the QVAC worker reloads or downloads models. It also validates every save and keeps recent configuration backups.
