    The class `MaritTalkConfig` provides configuration for the MaritTalk's API interface. Here are the parameters:

    - `max_tokens` (integer): Maximum number of tokens the model will generate as part of the response. Default is 1.

    - `model` (string): The model used for conversation. Default is 'maritalk'.

    - `do_sample` (boolean): If set to True, the API will generate a response using sampling. Default is True.

    - `temperature` (number): A non-negative float controlling the randomness in generation. Lower temperatures result in less random generations. Default is 0.7.

    - `top_p` (number): Selection threshold for token inclusion based on cumulative probability. Default is 0.95.

    - `repetition_penalty` (number): Penalty for repetition in the generated conversation. Default is 1.

    - `stopping_tokens` (list of string): List of tokens where the conversation can be stopped/stopped.
