# 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, self-hosted Inference Endpoints, or third-party Inference Providers.

    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 a URL is passed as `model` or `base_url` for chat completion, the `(/v1)/chat/completions` suffix path will be appended to the URL.
        provider (`str`, *optional*):
            Name of the provider to use for inference. Can be `"black-forest-labs"`, `"cerebras"`, `"clarifai"`, `"cohere"`, `"deepinfra"`, `"fal-ai"`, `"featherless-ai"`, `"fireworks-ai"`, `"groq"`, `"hf-inference"`, `"hyperbolic"`, `"nebius"`, `"novita"`, `"nscale"`, `"nvidia"`, `"openai"`, `"ovhcloud"`, `"publicai"`, `"replicate"`, `"sambanova"`, `"scaleway"`, `"together"`, `"wavespeed"` or `"zai-org"`.
            Defaults to "auto": automatic routing, which defaults to "fastest" provider; you can
            switch to "cheapest" or "preferred" provider order at https://hf.co/settings/inference-providers.
            If model is a URL or `base_url` is passed, then `provider` is not used.
        token (`str`, *optional*):
            Hugging Face token. Will default to the locally saved token if not provided.
            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. 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.
        bill_to (`str`, `optional`):
            The billing account to use for the requests. By default the requests are billed on the user's account.
            Requests can only be billed to an organization the user is a member of, and which has subscribed to Enterprise Hub.
        cookies (`dict[str, str]`, `optional`):
            Additional cookies to send to the server.
        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]
        > You can pass provider-specific parameters to the model by using the `extra_body` argument.

        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*):
                Adjusts the likelihood of specific tokens appearing in the generated output.
            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 100.
            n (`int`, *optional*):
                The number of completions to generate for each prompt.
            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 (`list[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 ([`ChatCompletionInputToolChoiceClass`] or [`ChatCompletionInputToolChoiceEnum`], *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.
            extra_body (`dict`, *optional*):
                Additional provider-specific parameters to pass to the model. Refer to the provider's documentation
                for supported parameters.
        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.
            [`HfHubHTTPError`]:
                If the request fails with an HTTP error status code other than HTTP 503.

        ```

        Example using OpenAI's syntax:
        ```py

        from huggingface_hub import InferenceClient

        # instead of `client = OpenAI(...)`
        client = InferenceClient(
            base_url=...,

        )

        for chunk in output:
            print(chunk.choices[0].delta.content)
        ```

        Example using a third-party provider directly with extra (provider-specific) parameters. Usage will be billed on your Together AI account.

        Given a prompt, generate the following text.

        > [!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.

        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. Defaults to 100.
            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.
            [`HfHubHTTPError`]:
                If the request fails with an HTTP error status code other than HTTP 503.

            epsilon_cutoff (`float`, *optional*):
                If set to float strictly between 0 and 1, only tokens with a conditional probability greater than
                epsilon_cutoff will be sampled. In the paper, suggested values range from 3e-4 to 9e-4, depending on
                the size of the model. See [Truncation Sampling as Language Model
                Desmoothing](https://hf.co/papers/2210.15191) for more details.
            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. See [Truncation Sampling as Language Model

            max_length (`int`, *optional*):
                The maximum length (in tokens) of the generated text, including the input.
            max_new_tokens (`int`, *optional*):
                The maximum number of tokens to generate. Takes precedence over max_length.
            min_length (`int`, *optional*):
                The minimum length (in tokens) of the generated text, including the input.
            min_new_tokens (`int`, *optional*):
                The minimum number of tokens to generate. Takes precedence over min_length.
            num_beam_groups (`int`, *optional*):
                Number of groups to divide num_beams into in order to ensure diversity among different groups of beams.
                See [this paper](https://hf.co/papers/1610.02424) for more details.
            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.
            top_k (`int`, *optional*):
                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
