        1) Additional typed keys and that this model requires to process inputs.
        2) Default values for existing keys under a `_defaults` attribute.
    New keys have to be defined as follows to ensure type hinting is done correctly.
    ```python

        (retrieval-augmented generation). If the template does not support RAG, this argument will have no
        effect. We recommend that each document should be a dict containing "title" and "text" keys. Please
        see the RAG section of the [chat templating guide](https://huggingface.co/docs/transformers/main/en/chat_templating#arguments-for-RAG)
        for examples of passing documents with chat templates.
    add_generation_prompt (bool, *optional*):
        If this is set, a prompt with the token(s) that indicate
        the start of an assistant message will be appended to the formatted output. This is useful when you want to generate a response from the model.
        Note that this argument will be passed to the chat template, and so it must be supported in the
        template for this argument to have any effect.
    continue_final_message (bool, *optional*):
        If this is set, the chat will be formatted so that the final
        message in the chat is open-ended, without any EOS tokens. The model will continue this message
        rather than starting a new one. This allows you to "prefill" part of
        the model's response for it. Cannot be used at the same time as `add_generation_prompt`.
    return_assistant_tokens_mask (`bool`, defaults to `False`):
        Whether to return a mask of the assistant generated tokens. For tokens generated by the assistant,
        the mask will contain 1. For user and system tokens, the mask will contain 0.
        This functionality is only available for chat templates that support it via the `{% generation %}` keyword.
    reasoning_effort (`str`, *optional*):
        The reasoning effort level to use for the model's response. Supported values depend on the model
        (e.g. `"none"`, "low"`, `"medium"`, `"high"`). If the template does not support reasoning effort,
        this argument will have no effect.
