May I know once I want to make a LLM by `BaseAPIModel`, where could I input the url_base?

I cannot find where can I input my url of my LLM on cloud. I should make one just like you do in GPTAPI, shoudn't I? So why this class called BaseAPIModel?

class BaseAPIModel(BaseModel):
    """Base class for API model wrapper.

    Args:
        model_type (str): The type of model.
        query_per_second (int): The maximum queries allowed per second
