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:

1
{
2
  "type": "Settings",
3
  "agent": {
4
    "think": {
5
      "provider": {
6
        "type": "open_ai",
7
        "model": "gpt-5",
8
        "reasoning_mode": "medium"
9
      }
10
    }

  }

}
