# Some TODO:
# - add all tasks
#
# NOTE: the philosophy of this client is "let's make it as easy as possible to use it, even if less optimized". Some
# examples of how it translates:
# - Timeout / Server unavailable is handled by the client in a single "timeout" parameter.
# - Files can be provided as bytes, file paths, or URLs and the client will try to "guess" the type.
# - Images are parsed as PIL.Image for easier manipulation.
# - Provides a "recommended model" for each task => suboptimal but user-wise quicker to get a first script running.
# - Only the main parameters are publicly exposed. Power users can always read the docs for more options.

class InferenceClient:
    """
    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. `meta-llama/Meta-Llama-3-8B-Instruct`
            or a URL to a deployed Inference Endpoint. Defaults to None, in which case a recommended model is
            automatically selected for the task.
            Note: for better compatibility with OpenAI's client, `model` has been aliased as `base_url`. Those 2
            arguments are mutually exclusive. If using `base_url` for chat completion, the `/chat/completions` suffix
            path will be appended to the base URL (see the [TGI Messages API](https://huggingface.co/docs/text-generation-inference/en/messages_api)
            documentation for details). When passing a URL as `model`, the client will not append any suffix path to it.
        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.
            Note: for better compatibility with OpenAI's client, `token` has been aliased as `api_key`. Those 2
            arguments are mutually exclusive and have the exact same behavior.
        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`):
            Additional cookies to send to the server.
        proxies (`Any`, `optional`):
            Proxies to use for the request.
        base_url (`str`, `optional`):
            Base URL to run inference. This is a duplicated argument from `model` to make [`InferenceClient`]
            follow the same pattern as `openai.OpenAI` client. Cannot be used if `model` is set. Defaults to None.
        api_key (`str`, `optional`):
            Token to use for authentication. This is a duplicated argument from `token` to make [`InferenceClient`]
            follow the same pattern as `openai.OpenAI` client. Cannot be used if `token` is set. Defaults to None.

        A method for completing conversations using a specified language model.

        <Tip>

        The `client.chat_completion` method is aliased as `client.chat.completions.create` for compatibility with OpenAI's client.
        Inputs and outputs are strictly the same and using either syntax will yield the same results.
        Check out the [Inference guide](https://huggingface.co/docs/huggingface_hub/guides/inference#openai-compatibility)
        for more details about OpenAI's compatibility.

        </Tip>

        Args:
            messages (List of [`ChatCompletionInputMessage`]):
                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.

                If `model` is a model ID, it is passed to the server as the `model` parameter. If you want to define a
                custom URL while setting `model` in the request payload, you must set `base_url` when initializing [`InferenceClient`].
            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.
            response_format ([`ChatCompletionInputGrammarType`], *optional*):
                Grammar constraints. Can be either a JSONSchema or a regex.
            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.
            stream_options ([`ChatCompletionInputStreamOptions`], *optional*):
                Options for streaming completions.
            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 ([`ChatCompletionInputToolType`] or `str`, *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 [`ToolElement`], *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.
            `HTTPError`:
                If the request fails with an HTTP error status code other than HTTP 503.

        `text-generation-inference`. If some parameters are ignored, a warning message is triggered but the process
        continues correctly.

        <Tip>

        If you want to generate a response from chat messages, you should use the [`InferenceClient.chat_completion`] method.
        It accepts a list of messages instead of a single text prompt and handles the chat templating for you.

        </Tip>

        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.
            adapter_id (`str`, *optional*):
                Lora adapter id.
            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 (`List[str]`, *optional*):
                Stop generating tokens if a member of `stop` is generated.
            stop_sequences (`List[str]`, *optional*):
                Deprecated argument. Use `stop` instead.
            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.
            `HTTPError`:
                If the request fails with an HTTP error status code other than HTTP 503.

            eta_cutoff (`float`, *optional*):
                Eta sampling is a hybrid of locally typical sampling and epsilon sampling. If set to
                float strictly between 0 and 1, a token is only considered if it is greater than either
                eta_cutoff or sqrt(eta_cutoff) * exp(-entropy(softmax(next_token_logits))). The latter
                term is intuitively the expected next token probability, scaled by sqrt(eta_cutoff). In
                the paper, suggested values range from 3e-4 to 2e-3, depending on the size of the model.

            num_beam_groups (`int`, *optional*):
                Number of groups to divide num_beams into in order to ensure diversity among different

            num_beams (`int`, *optional*):
                Number of beams to use for beam search.
            penalty_alpha (`float`, *optional*):
                The value balances the model confidence and the degeneration penalty in contrastive
                search decoding.
            temperature (`float`, *optional*):
                The value used to modulate the next token probabilities.

                The number of highest probability vocabulary tokens to keep for top-k-filtering.
            top_p (`float`, *optional*):
                If set to float < 1, only the smallest set of most probable tokens with probabilities
                that add up to top_p or higher are kept for generation.
            typical_p (`float`, *optional*):
                Local typicality measures how similar the conditional probability of predicting a target token next is
                to the expected conditional probability of predicting a random token next, given the partial text
                already generated. If set to float < 1, the smallest set of the most locally typical tokens with
                probabilities that add up to typical_p or higher are kept for generation. See [this

                List of strings. Each string is the verbalization of a possible label for the input text.
            multi_label (`bool`):
                Boolean. If True, the probability for each label is evaluated independently and multiple labels can have a probability close to 1 simultaneously or all probabilities can be close to 0.
                If False, the labels are considered mutually exclusive and the probability over all labels always sums to 1. Defaults to False.
            hypothesis_template (`str`, *optional*):
                A template sentence string with curly brackets to which the label strings are added. The label strings are added at the position of the curly brackets "{}".
                Zero-shot classifiers are based on NLI models, which evaluate if a hypothesis is entailed in another text or not.
                For example, with hypothesis_template="This text is about {}." and labels=["economics", "politics"], the system internally creates the two hypotheses "This text is about economics." and "This text is about politics.".
                The model then evaluates for both hypotheses if they are entailed in the provided `text` or not.
            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. If not provided, the default recommended zero-shot classification model will be used.

        Returns:
            `List[ZeroShotClassificationOutputElement]`: List of [`ZeroShotClassificationOutputElement`] items containing the predicted labels and their confidence.

        Raises:
            [`InferenceTimeoutError`]:
                If the model is unavailable or the request times out.
            `HTTPError`:
