+| Effort | Best For |

+| `low` | Simple lookups on one site |
+| `medium` | Multi-step tasks on a few pages |

+Every effort level runs the `spark-2` model. Effort changes the reasoning
+budget, not the model.

+#### Model Selection (Legacy)
+
+`model` still works, and it stays supported. Send `model` or `effort`, not
+both. A request with both fields returns a 400 error.
