    Reference: https://platform.openai.com/docs/api-reference/chat/create

    The class `OpenAIConfig` provides configuration for the OpenAI's Chat API interface. Below are the parameters:

    - `frequency_penalty` (number or null): Defaults to 0. Allows a value between -2.0 and 2.0. Positive values penalize new tokens based on their existing frequency in the text so far, thereby minimizing repetition.

    - `function_call` (string or object): This optional parameter controls how the model calls functions.

    - `functions` (array): An optional parameter. It is a list of functions for which the model may generate JSON inputs.

    - `logit_bias` (map): This optional parameter modifies the likelihood of specified tokens appearing in the completion.

    - `max_tokens` (integer or null): This optional parameter helps to set the maximum number of tokens to generate in the chat completion. OpenAI has now deprecated in favor of max_completion_tokens, and is not compatible with o1 series models.

    - `max_completion_tokens` (integer or null): An upper bound for the number of tokens that can be generated for a completion, including visible output tokens and reasoning tokens.

    - `n` (integer or null): This optional parameter helps to set how many chat completion choices to generate for each input message.

    - `presence_penalty` (number or null): Defaults to 0. It penalizes new tokens based on if they appear in the text so far, hence increasing the model's likelihood to talk about new topics.

    - `stop` (string / array / null): Specifies up to 4 sequences where the API will stop generating further tokens.

    - `temperature` (number or null): Defines the sampling temperature to use, varying between 0 and 2.

    - `top_p` (number or null): An alternative to sampling with temperature, used for nucleus sampling.
