The system automatically routes models to the appropriate provider:

2. Entries in `conf/openrouter_models_live.json` and `conf/openrouter_models.json` → Routed through OpenRouter (requires `OPENROUTER_API_KEY`)
3. **Unknown models** → Fallback logic based on model name patterns

3. Entries in `conf/openrouter_models_live.json` and `conf/openrouter_models.json` → Routed through OpenRouter (requires `OPENROUTER_API_KEY`)
4. **Unknown models** → Fallback logic based on model name patterns
**Provider Priority Order:**
1. Native APIs (Google, OpenAI) - if API keys are available
2. Custom endpoints - for models declared in `conf/custom_models.json`
3. OpenRouter - catch-all for cloud models
2. OpenCode Zen - curated gateway models
3. Custom endpoints - for models declared in `conf/custom_models.json`
4. OpenRouter - catch-all for cloud models

### Adding Custom Models
Edit `conf/openrouter_models.json` to tweak OpenRouter behaviour or `conf/custom_models.json` to add local models. The generated `conf/openrouter_models_live.json` file is discovery data from OpenRouter's `/api/v1/models` endpoint; curated entries in `conf/openrouter_models.json` override those generated defaults. Each entry maps directly onto [`ModelCapabilities`](../providers/shared/model_capabilities.py).
Edit `conf/zen_models.json` to tweak OpenCode Zen behaviour, `conf/openrouter_models.json` to tweak OpenRouter behaviour, or `conf/custom_models.json` to add local models. The generated `conf/zen_models_live.json` and `conf/openrouter_models_live.json` files are discovery data from the upstream model listing endpoints; curated entries override those generated defaults. Each entry maps directly onto [`ModelCapabilities`](../providers/shared/model_capabilities.py).
### Refreshing the Live OpenCode Zen Catalogue
Run the sync script whenever OpenCode Zen adds or removes models that you want `listmodels` and provider enumeration to expose, or before cutting a release that should include an updated Zen catalogue.
```bash
source .pal_venv/bin/activate
python scripts/sync_zen_models.py
```
By default the script:
- fetches `https://opencode.ai/zen/v1/models`
- writes conservative discovery data to `conf/zen_models_live.json`
- leaves `conf/zen_models.json` untouched
Use the optional flags if you need to test against a different endpoint or write to a different file:
```bash
python scripts/sync_zen_models.py --url https://opencode.ai/zen/v1/models --output conf/zen_models_live.json
```
Important runtime behavior:
- `conf/zen_models_live.json` is the generated baseline catalogue
- `conf/zen_models.json` is the curated override layer for aliases and PAL-specific capability flags
- curated entries win when the same `model_name` appears in both files
- models missing from the curated file are still available from the generated catalogue
After refreshing the catalogue:
1. Review the diff in `conf/zen_models_live.json`
2. Add or update curated entries in `conf/zen_models.json` if a new model needs aliases or PAL-specific capability tweaks
3. Restart the server so the updated manifests are reloaded
4. Commit the generated JSON alongside any curated overrides so other contributors get the same catalogue state
