Inference

Inference is the process of using a trained model to make predictions on new data. As this process can be compute-intensive, running on a dedicated server can be an interesting option. The huggingface_hub library provides an easy way to call a service that runs inference for hosted models. There are several services you can connect to:

Inference API: a service that allows you to run accelerated inference on Model Database’s infrastructure for free. This service is a fast way to get started, test different models, and prototype AI products.
Inference Endpoints: a product to easily deploy models to production. Inference is run by Model Database in a dedicated, fully managed infrastructure on a cloud provider of your choice.

These services can be called with the InferenceClient object. Please refer to this guide for more information on how to use it.

Inference Client

class huggingface_hub.InferenceClient

( model: typing.Optional[str] = None token: typing.Union[str, bool, NoneType] = None timeout: typing.Optional[float] = None headers: typing.Union[typing.Dict[str, str], NoneType] = None cookies: typing.Union[typing.Dict[str, str], NoneType] = None )

Parameters

model (str, optional) — The model to run inference with. Can be a model id hosted on the Model Database 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, optional) — Model Database token. Will default to the locally saved token. 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) — Additional cookies to send to the server.

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.

However, if you want a complete list of models you can specify frameworks="all" as input. Alternatively, if you know before-hand which framework you are interested in, you can also restrict to search to this one (e.g. frameworks="text-generation-inference"). The more frameworks are checked, the more time it will take.

This endpoint is mostly useful for discoverability. If you already know which model you want to use and want to check its availability, you can directly use get_model_status().

Given a prompt, generate the following text.

It is recommended to have Pydantic installed in order to get inputs validated. This is preferable as it allow early failures.

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.

However, if you want a complete list of models you can specify frameworks="all" as input. Alternatively, if you know before-hand which framework you are interested in, you can also restrict to search to this one (e.g. frameworks="text-generation-inference"). The more frameworks are checked, the more time it will take.

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.

InferenceAPI

InferenceAPI is the legacy way to call the Inference API. The interface is more simplistic and requires knowing the input parameters and output format for each task. It also lacks the ability to connect to other services like Inference Endpoints or AWS SageMaker. InferenceAPI will soon be deprecated so we recommend using InferenceClient whenever possible. Check out this guide to learn how to switch from InferenceAPI to InferenceClient in your scripts.

class huggingface_hub.InferenceApi

( repo_id: str task: typing.Optional[str] = None token: typing.Optional[str] = None gpu: bool = False )

Client to configure requests and make calls to the HuggingFace Inference API.

Example:

>>> from huggingface_hub.inference_api import InferenceApi

>>> # Mask-fill example
>>> inference = InferenceApi("bert-base-uncased")
>>> inference(inputs="The goal of life is [MASK].")
[{'sequence': 'the goal of life is life.', 'score': 0.10933292657136917, 'token': 2166, 'token_str': 'life'}]

>>> # Question Answering example
>>> inference = InferenceApi("deepset/roberta-base-squad2")
>>> inputs = {
...     "question": "What's my name?",
...     "context": "My name is Clara and I live in Berkeley.",
... }
>>> inference(inputs)
{'score': 0.9326569437980652, 'start': 11, 'end': 16, 'answer': 'Clara'}

>>> # Zero-shot example
>>> inference = InferenceApi("typeform/distilbert-base-uncased-mnli")
>>> inputs = "Hi, I recently bought a device from your company but it is not working as advertised and I would like to get reimbursed!"
>>> params = {"candidate_labels": ["refund", "legal", "faq"]}
>>> inference(inputs, params)
{'sequence': 'Hi, I recently bought a device from your company but it is not working as advertised and I would like to get reimbursed!', 'labels': ['refund', 'faq', 'legal'], 'scores': [0.9378499388694763, 0.04914155602455139, 0.013008488342165947]}

>>> # Overriding configured task
>>> inference = InferenceApi("bert-base-uncased", task="feature-extraction")

>>> # Text-to-image
>>> inference = InferenceApi("stabilityai/stable-diffusion-2-1")
>>> inference("cat")
<PIL.PngImagePlugin.PngImageFile image (...)>

>>> # Return as raw response to parse the output yourself
>>> inference = InferenceApi("mio/amadeus")
>>> response = inference("hello world", raw_response=True)
>>> response.headers
{"Content-Type": "audio/flac", ...}
>>> response.content # raw bytes from server
b'(...)'
