!!! tip "When to use this model"

* Use this model class when you want to use OpenAI's [Responses API](https://platform.openai.com/docs/api-reference/responses) (previously called the Chat Completions API with streaming enabled).
* This is particularly useful for models like GPT-5 that benefit from the extended thinking/reasoning capabilities provided by the Responses API.

Usage

To use the Response API model, specify model_class: "litellm_response" in your agent config:

model:
  model_class: "litellm_response"
  model_name: "openai/gpt-5.1"
  model_kwargs:
    drop_params: true
    reasoning:
      effort: "medium"
    text:
      verbosity: "medium"

Or via command line:

mini -m "openai/gpt-5-mini" --model-class litellm_response
