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` |
|

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`): |

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. |

|
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. |
|
|
|
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. |
|
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 `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 [`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. |
|
`HTTPError`: |
|
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. |
|
|
|
<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_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`] |
|

|
`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. |

This endpoint is mostly useful when you already know which model you want to use and want to check its |
