    SiliconFlow API.

    Args:
        temperature (float, optional): Determines the degree of randomness
            in the response. (default: :obj:`None`)
        top_p (float, optional): The top_p (nucleus) parameter is used to
            dynamically adjust the number of choices for each predicted token
            based on the cumulative probabilities. (default: :obj:`None`)
        n (int, optional): Number of generations to return.
            (default: :obj:`None`)
        response_format (object, optional): An object specifying the format
            that the model must output. (default: :obj:`None`)
        stream (bool, optional): If set, tokens are returned as Server-Sent
            Events as they are made available. (default: :obj:`None`)
        stop (str or list, optional): Up to :obj:`4` sequences where the API
            will stop generating further tokens. (default: :obj:`None`)
        max_tokens (int, optional): The maximum number of tokens to generate.
            (default: :obj:`None`)
        frequency_penalty (float, optional): Number between :obj:`-2.0` and
            :obj:`2.0`. Positive values penalize new tokens based on their
            existing frequency in the text so far, decreasing the model's
            likelihood to repeat the same line verbatim. See more information
            about frequency and presence penalties. (default: :obj:`None`)
        tools (list[FunctionTool], optional): A list of tools the model may
            call. Currently, only functions are supported as a tool. Use this
            to provide a list of functions the model may generate JSON inputs
            for. A max of 128 functions are supported. (default: :obj:`None`)
