This online platform facilitates seamless collaboration for building machine learning solutions together. + +Additionally, the Hugging Face Hub offers a variety of endpoints for developing diverse ML applications. This example illustrates how to connect to different types of endpoints. + +Notably, text generation inference is powered by Text Generation Inference, a custom-built server using Rust, Python, and gRPC, designed for exceptionally fast text generation inference. + +## Obtaining a Huggingface Token + +After signing up on Hugging Face, you can obtain a token from the following URL. +- URL : https://huggingface.co/docs/hub/security-tokens + +## Reference Model List + +- Huggingface LLM Leaderboard : https://huggingface.co/spaces/HuggingFaceH4/open_llm_leaderboard +- Model list : https://huggingface.co/models?pipeline_tag=text-generation&sort=downloads +- LogicKor Leaderboard : https://lk.instruct.kr/ + LogicKor Leaderboard's link is for the leaderboard of Korean models. As the model performance increased, it has been archived due to meaningless scores as of October 17, 2024. However, you can find the best-performing Korean models. + +## Using Hugging Face Endpoints +To use Hugging Face Endpoints, install the `huggingface_hub` package in Python. +We previously installed `huggingface_hub` through `langchain-opentutorial`. However, if you need to install it separately, you can do so by running the `pip install huggingface_hub` command. + +To use the Hugging Face endpoint, you need an API token key. If you don't have a huggingface token follwing this [here](#Obtaining-a-Huggingface-Token). + +If you have already set the token in `HUGGINGFACEHUB_API_TOKEN`, the API token is automatically recognized. + +**OR** + +You can use `from huggingface_hub import login`. + + +```python +import os +from huggingface_hub import login + +if not os.environ['HUGGINGFACEHUB_API_TOKEN']: + login() +else: + print("You have a HUGGINGFACEHUB_API_TOKEN") +``` + + You have a HUGGINGFACEHUB_API_TOKEN + + +You can choose either of the two methods above and use it. + +## Serverless Endpoints + +The Inference API is free to use but comes with usage limitations. For production-level inference solutions, consider using the [Inference Endpoints](https://huggingface.co/docs/inference-endpoints/index) service. Inference Endpoints enable you to deploy any machine learning model seamlessly on dedicated, fully managed infrastructure. You can tailor the deployment to align with your model, latency, throughput, and compliance requirements by selecting the cloud provider, region, compute instance, auto-scaling range, and security level. + +Below is an example of how to access the Inference API. + +- [Serverless Endpoints](https://huggingface.co/docs/api-inference/index) +- [Inference Endpoints](https://huggingface.co/docs/inference-endpoints/index) + +First of all, create a simple prompt using `PromptTemplate` + + +```python +from langchain_core.prompts import PromptTemplate + +template = """<|system|> +You are a helpful assistant.<|end|> +<|user|> +{question}<|end|> +<|assistant|>""" + +prompt = PromptTemplate.from_template(template) +``` + +**[Note]** +- In this example, the model used is `microsoft/Phi-3-mini-4k-instruct` +- If you want change aother model, assign the HuggingFace model's repository ID to the variable `repo_id`. +- link : https://huggingface.co/microsoft/Phi-3-mini-4k-instruct + + +```python +from langchain_core.output_parsers import StrOutputParser +from langchain_huggingface import HuggingFaceEndpoint + +# Set the repository ID of the model to be used. +repo_id = "microsoft/Phi-3-mini-4k-instruct" + +llm = HuggingFaceEndpoint( + repo_id=repo_id, # Specify the model repository ID. + max_new_tokens=256, # Set the maximum token length for generation. + temperature=0.1, +) + +# Initialize the LLMChain and pass the prompt and language model. +chain = prompt | llm | StrOutputParser() +# Execute the LLMChain by providing a question and print the result. +response = chain.invoke({"question": "what is the capital of South Korea?"}) +``` + +The response is below : + + +```python +print(response) +``` + + The capital of South Korea is Seoul. Seoul is not only the capital but also the largest metropolis in South Korea. It is a bustling city known for its modern skyscrapers, high-tech subways, and pop culture, as well as its historical sites such as palaces, temples, and traditional markets. + + +## Dedicated Endpoints +Using free serverless APIs allows you to quickly implement and iterate your solutions. However, because the load is shared with other requests, there can be rate limits for high-volume use cases. + +For enterprise workloads, it is recommended to use [Inference Endpoints - Dedicated](https://huggingface.co/inference-endpoints/dedicated). This gives you access to a fully managed infrastructure that offers greater flexibility and speed. + +These resources also include ongoing support, guaranteed uptime, and options like AutoScaling. + +- Set the Inference Endpoint URL to the `hf_endpoint_url` variable. + +**[Note]** +- This address(https://api-inference.huggingface.co/models/Qwen/QwQ-32B-Preview) is not a Dedicated Endpoint but rather a public endpoint provided by Hugging Face.
