## Reasoning mode for OpenAI thinking models

You can now control the reasoning effort of supported OpenAI reasoning models using the new `reasoning_mode` parameter in the think provider configuration. This parameter maps to OpenAI's `reasoning_effort` and accepts `low`, `medium`, or `high`.

**Example:**

```json
{
  "type": "Settings",
  "agent": {
    "think": {
      "provider": {
        "type": "open_ai",
        "model": "gpt-5",
        "reasoning_mode": "medium"
      }
    }
  }
}
```
