# Pi Configuration

Add to `~/.pi/agent/models.json`:

```json
{
  "providers": {
    "llamacpp (local-ornith)": {
      "baseUrl": "http://localhost:8080/v1",
      "api": "openai-completions",
      "apiKey": "EMPTY",
      "compat": {
        "supportsDeveloperRole": false,
        "supportsReasoningEffort": false
      },
      "models": [
        {
          "id": "frank-default-local",
          "name": "Ornith-1.0-35B-Q4_K_M (Local)",
          "contextWindow": 131072,
          "reasoning": true,
          "thinkingLevelMap": {
            "max": "xhigh"
          }
        }
      ]
    }
  }
}
```

**Important Compatibility Settings:**

- `supportsDeveloperRole: false` — The server does not support the `developer` role, uses `system` instead
- `supportsReasoningEffort: false` — The server does not support the `reasoning_effort` parameter
- `reasoning: true` — Model supports reasoning/thinking blocks
