Step-by-Step: Hosting Your Model on Hugging Face

1. Preparing Your Model

Before uploading, ensure your model is ready for sharing:

  • Save Model Artifacts: Export your trained model in a compatible format (e.g., PyTorch .pt, TensorFlow .h5, or ONNX).
  • Include Configurations: Save any required config files (e.g., tokenizer, labels, settings).
  • Write a README: Create a README.md describing your model’s purpose, training data, usage, and limitations.

2. Create a Hugging Face Account

If you haven’t already:

  • Sign up on Hugging Face.
  • Verify your email and complete your profile for collaboration benefits.

3. Install Hugging Face Hub Tools

You’ll often want to use the Hugging Face Hub CLI and/or the transformers Python library:

pip install huggingface_hub

Or, for Transformers-based models:

pip install transformers

4. Log in to the CLI

Authenticate your CLI with your Hugging Face credentials:

huggingface-cli login

You’ll be prompted for your Hugging Face access token (available in your account settings).

5. Initialize a Model Repository

You can create a new repository directly from the website, or via CLI:

huggingface-cli repo create your-model-name

Or, via the website:
– Navigate to your profile on Hugging Face.
– Click “New Model” and follow the prompts.

6. Organize Model Files Locally

Your model folder should contain:

  • Model weights (e.g., pytorch_model.bin)
  • Config files (e.g., config.json, tokenizer.json, vocab.txt)
  • README.md
  • Additional scripts or notebooks (optional)

7. Upload Your Model

There are several ways:

Using Git

  1. Clone your empty model repository:

bash
git lfs install # For large files
git clone https://huggingface.co/your-username/your-model-name
cd your-model-name

  1. Copy your model files into this folder.
  2. Commit and push:

bash
git add .
git commit -m "Initial model upload"
git push

Using Python Code

Alternatively, upload directly from a Python script using huggingface_hub:

from huggingface_hub import HfApi

api = HfApi()
api.upload_folder(
    folder_path="path_to_your_model_folder",
    repo_id="your-username/your-model-name"
)

8. Document Your Model

  • Complete the README.md with clear instructions—this helps others understand and use your model.
  • Highlight training data, intended use cases, and any warnings.

9. (Optional) Add Model Card Metadata

Model cards contain structured metadata and are recommended for better discoverability. You can add tags, tasks, and dataset details.

Hosting an Interactive Demo with Hugging Face Spaces

Want to let people interact with your model in a live web app? Use Hugging Face Spaces!

What are Spaces?

Spaces are hosted web applications powered by frameworks like Gradio or Streamlit. They allow anyone to try your model in the browser.

How to Launch a Space

  1. From your Hugging Face account, go to the “Spaces” tab.
  2. Click “Create new Space.”
  3. Select a framework (Gradio or Streamlit are simple and popular).
  4. Upload the Python app file (e.g., app.py) and your model files.
  5. The Space is built and publicly available with a clickable interface.

Pro-tip: Spaces are perfect for demonstrations, user feedback, and prototyping ML-powered applications.

Turning Your Model into an API

If you want programmatic access (e.g., from a web server or app), use Hugging Face’s Inference Endpoints.

Overview

  • Inference Endpoints let you deploy models as scalable REST APIs, handling underlying infrastructure automatically.

Basic Process

  1. Go to your hosted model page.
  2. Click “Deploy” and select “Inference Endpoint.”
  3. Choose your settings (cloud provider, region, hardware).
  4. Deploy and get your API URL + access token.

Note: Free endpoints are limited; paid plans remove restrictions.

Best Practices for Model Hosting

To ensure smooth and effective collaboration on Hugging Face, follow these tips:

  • Keep Your README Clear: Explain model architecture, training data, performance, and intended use cases.
  • Organize Files: Stick to common file naming conventions and package all required files (model, tokenizer, labels).
  • Add Licensing Information: Let others know how they can use your model.
  • Use Versioning: Tag releases for major updates.
  • Test Before Sharing: Make sure all files load properly and run a minimal example.
  • Use Relevant Tags: Add tags for tasks, languages, and datasets for easier discoverability.
  • Consider Security: Avoid uploading private data or credentials.

Practical Tips and Advice

  • Model Size: Large models (>100MB) require Git LFS for handling big files.
  • Private vs Public Repos: Sensitive or proprietary models can be shared privately.
  • Community Contributions: Encourage users to open issues or PRs for improvements.
  • Continuous Integration: Use automated tools like GitHub Actions for automated model testing.
  • API Limits: Be aware of rate and usage limits for free tier endpoints.

Cost Tips for Model Hosting

  • Model Hosting: Hosting on the Model Hub is free for public models.
  • Spaces: Free for lightweight Gradio/Streamlit apps; heavy compute use may require paid “Pro” subscription.
  • Inference Endpoints: Free limited-tier APIs; for high-traffic or unique hardware, costs can apply.
  • Data Transfer: No explicit “shipping” fee, but extremely large models may have slow upload/download times—keep files optimized and compressed when possible.

Challenges and Things to Watch

  • Upload Limits: Some files or models are too large for the default limits; use appropriate tools (like LFS) or split files if necessary.
  • Dependency Issues: For Spaces, list all requirements in a requirements.txt or environment.yaml.
  • Model Privacy: Keep sensitive data, proprietary weights, and license information secure.
  • API Latency: Hosted APIs can have network latency; optimize your model for inference speed if possible.
  • Obsolete Dependencies: Ensure your code uses actively maintained libraries.

Frequently Asked Questions (FAQs)

How do I share a model with collaborators privately?

You can set your repository to private when you create it or via settings later. Only invited users will have access. This ensures model files and documentation are secure.

What frameworks are supported for interactive demos in Spaces?

Spaces currently supports popular Python web frameworks, notably Gradio, Streamlit, and Static HTML apps. Gradio is highly recommended for fast prototyping and ease of use.

Is there a limit to the number or size of models I can upload?

Public models generally have generous storage limits, but huge models (>5GB) might require special handling. For very large models, use Git LFS and consult Hugging Face documentation for best practices.
