class OpenAIModel(BaseModelBackend):

OpenAI API in a unified BaseModelBackend interface.

Parameters:

  • model_type (Union[ModelType, str]): Model for which a backend is created, one of GPT_* series.
  • model_config_dict (Optional[Dict[str, Any]], optional): A dictionary that will be fed into:obj:openai.ChatCompletion.create(). If :obj:None, :obj:ChatGPTConfig().as_dict() will be used. (default: :obj:None)
  • api_key (Optional[str], optional): The API key for authenticating with the OpenAI service. (default: :obj:None)
  • url (Optional[str], optional): The url to the OpenAI service. (default: :obj:None)
  • token_counter (Optional[BaseTokenCounter], optional): Token counter to use for the model. If not provided, :obj:OpenAITokenCounter will be used. (default: :obj:None)
  • timeout (Optional[float], optional): The timeout value in seconds for API calls. If not provided, will fall back to the MODEL_TIMEOUT environment variable or default to 180 seconds. (default: :obj:None)
  • max_retries (int, optional): Maximum number of retries for API calls. (default: :obj:3) **kwargs (Any): Additional arguments to pass to the OpenAI client initialization. These can include parameters like ‘organization’, ‘default_headers’, ‘http_client’, etc.
