    Initialize a new Inference Client.

    [`InferenceClient`] aims to provide a unified experience to perform inference. The client can be used
    seamlessly with either the (free) Inference API or self-hosted Inference Endpoints.

    Args:
        model (`str`, `optional`):
            The model to run inference with. Can be a model id hosted on the Hugging Face Hub, e.g. `bigcode/starcoder`
            or a URL to a deployed Inference Endpoint. Defaults to None, in which case a recommended model is
            automatically selected for the task.
        token (`str` or `bool`, *optional*):
            Hugging Face token. Will default to the locally saved token if not provided.
            Pass `token=False` if you don't want to send your token to the server.
        timeout (`float`, `optional`):
            The maximum number of seconds to wait for a response from the server. Loading a new model in Inference
            API can take up to several minutes. Defaults to None, meaning it will loop until the server is available.
        headers (`Dict[str, str]`, `optional`):
            Additional headers to send to the server. By default only the authorization and user-agent headers are sent.
            Values in this dictionary will override the default values.
        cookies (`Dict[str, str]`, `optional`):

        A method for completing conversations using a specified language model.

        <Tip>

        If the model is served by a server supporting chat-completion, the method will directly call the server's
        `/v1/chat/completions` endpoint. If the server does not support chat-completion, the method will render the
        chat template client-side based on the information fetched from the Hub API. In this case, you will need to
        have `minijinja` template engine installed. Run `pip install "huggingface_hub[inference]"` or `pip install minijinja`
        to install it.

        </Tip>

        Args:
            messages (List[Union[`SystemMessage`, `UserMessage`, `AssistantMessage`]]):
                Conversation history consisting of roles and content pairs.
            model (`str`, *optional*):
                The model to use for chat-completion. Can be a model ID hosted on the Hugging Face Hub or a URL to a deployed
                Inference Endpoint. If not provided, the default recommended model for chat-based text-generation will be used.
                See https://huggingface.co/tasks/text-generation for more details.
            frequency_penalty (`float`, *optional*):
                Penalizes new tokens based on their existing frequency
                in the text so far. Range: [-2.0, 2.0]. Defaults to 0.0.
            logit_bias (`List[float]`, *optional*):
                Modify the likelihood of specified tokens appearing in the completion. Accepts a JSON object that maps tokens
                (specified by their token ID in the tokenizer) to an associated bias value from -100 to 100. Mathematically,
                the bias is added to the logits generated by the model prior to sampling. The exact effect will vary per model,
                but values between -1 and 1 should decrease or increase likelihood of selection; values like -100 or 100 should
                result in a ban or exclusive selection of the relevant token. Defaults to None.
            logprobs (`bool`, *optional*):
                Whether to return log probabilities of the output tokens or not. If true, returns the log
                probabilities of each output token returned in the content of message.
            max_tokens (`int`, *optional*):
                Maximum number of tokens allowed in the response. Defaults to 20.
            n (`int`, *optional*):
                UNUSED.
            presence_penalty (`float`, *optional*):
                Number between -2.0 and 2.0. Positive values penalize new tokens based on whether they appear in the
                text so far, increasing the model's likelihood to talk about new topics.
            seed (Optional[`int`], *optional*):
                Seed for reproducible control flow. Defaults to None.
            stop (Optional[`str`], *optional*):
                Up to four strings which trigger the end of the response.
                Defaults to None.
            stream (`bool`, *optional*):
                Enable realtime streaming of responses. Defaults to False.
            temperature (`float`, *optional*):
                Controls randomness of the generations. Lower values ensure
                less random completions. Range: [0, 2]. Defaults to 1.0.
            top_logprobs (`int`, *optional*):
                An integer between 0 and 5 specifying the number of most likely tokens to return at each token
                position, each with an associated log probability. logprobs must be set to true if this parameter is
                used.
            top_p (`float`, *optional*):
                Fraction of the most likely next words to sample from.
                Must be between 0 and 1. Defaults to 1.0.
            tool_choice ([`ChatCompletionInputToolTypeClass`] or [`ChatCompletionInputToolTypeEnum`], *optional*):
                The tool to use for the completion. Defaults to "auto".
            tool_prompt (`str`, *optional*):
                A prompt to be appended before the tools.
            tools (List of [`ChatCompletionInputTool`], *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.

        Returns:
            [`ChatCompletionOutput] or Iterable of [`ChatCompletionStreamOutput`]:
            Generated text returned from the server:
            - if `stream=False`, the generated text is returned as a [`ChatCompletionOutput`] (default).
            - if `stream=True`, the generated text is returned token by token as a sequence of [`ChatCompletionStreamOutput`].

        Raises:
            [`InferenceTimeoutError`]:
                If the model is unavailable or the request times out.
            `aiohttp.ClientResponseError`:
                If the request fails with an HTTP error status code other than HTTP 503.

        Given a prompt, generate the following text.

        API endpoint is supposed to run with the `text-generation-inference` backend (TGI). This backend is the
        go-to solution to run large language models at scale. However, for some smaller models (e.g. "gpt2") the
        default `transformers` + `api-inference` solution is still in use. Both approaches have very similar APIs, but
        not exactly the same. This method is compatible with both approaches but some parameters are only available for
        `text-generation-inference`. If some parameters are ignored, a warning message is triggered but the process
        continues correctly.

        To learn more about the TGI project, please refer to https://github.com/huggingface/text-generation-inference.

        Args:
            prompt (`str`):
                Input text.
            details (`bool`, *optional*):
                By default, text_generation returns a string. Pass `details=True` if you want a detailed output (tokens,
                probabilities, seed, finish reason, etc.). Only available for models running on with the
                `text-generation-inference` backend.
            stream (`bool`, *optional*):
                By default, text_generation returns the full generated text. Pass `stream=True` if you want a stream of
                tokens to be returned. Only available for models running on with the `text-generation-inference`
                backend.
            model (`str`, *optional*):
                The model to use for inference. Can be a model ID hosted on the Hugging Face Hub or a URL to a deployed
                Inference Endpoint. This parameter overrides the model defined at the instance level. Defaults to None.
            best_of (`int`, *optional*):
                Generate best_of sequences and return the one if the highest token logprobs.
            decoder_input_details (`bool`, *optional*):
                Return the decoder input token logprobs and ids. You must set `details=True` as well for it to be taken
                into account. Defaults to `False`.
            do_sample (`bool`, *optional*):
                Activate logits sampling
            frequency_penalty (`float`, *optional*):
                Number between -2.0 and 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.
            grammar ([`TextGenerationInputGrammarType`], *optional*):
                Grammar constraints. Can be either a JSONSchema or a regex.
            max_new_tokens (`int`, *optional*):
                Maximum number of generated tokens
            repetition_penalty (`float`, *optional*):
                The parameter for repetition penalty. 1.0 means no penalty. See [this
                paper](https://arxiv.org/pdf/1909.05858.pdf) for more details.
            return_full_text (`bool`, *optional*):
                Whether to prepend the prompt to the generated text
            seed (`int`, *optional*):
                Random sampling seed
            stop_sequences (`List[str]`, *optional*):
                Stop generating tokens if a member of `stop_sequences` is generated
            temperature (`float`, *optional*):
                The value used to module the logits distribution.
            top_n_tokens (`int`, *optional*):
                Return information about the `top_n_tokens` most likely tokens at each generation step, instead of
                just the sampled token.
            top_k (`int`, *optional`):
                The number of highest probability vocabulary tokens to keep for top-k-filtering.
            top_p (`float`, *optional`):
                If set to < 1, only the smallest set of most probable tokens with probabilities that add up to `top_p` or
                higher are kept for generation.
            truncate (`int`, *optional`):
                Truncate inputs tokens to the given size.
            typical_p (`float`, *optional`):
                Typical Decoding mass
                See [Typical Decoding for Natural Language Generation](https://arxiv.org/abs/2202.00666) for more information
            watermark (`bool`, *optional`):
                Watermarking with [A Watermark for Large Language Models](https://arxiv.org/abs/2301.10226)

        Returns:
            `Union[str, TextGenerationOutput, Iterable[str], Iterable[TextGenerationStreamOutput]]`:
            Generated text returned from the server:
            - if `stream=False` and `details=False`, the generated text is returned as a `str` (default)
            - if `stream=True` and `details=False`, the generated text is returned token by token as a `Iterable[str]`
            - if `stream=False` and `details=True`, the generated text is returned with more details as a [`~huggingface_hub.TextGenerationOutput`]
            - if `details=True` and `stream=True`, the generated text is returned token by token as a iterable of [`~huggingface_hub.TextGenerationStreamOutput`]

        Raises:
            `ValidationError`:
                If input values are not valid. No HTTP call is made to the server.
            [`InferenceTimeoutError`]:
                If the model is unavailable or the request times out.
            `aiohttp.ClientResponseError`:
                If the request fails with an HTTP error status code other than HTTP 503.
