Hugging Face Spaces

Hugging Face Spaces is a hosting platform for AI demos and small web apps. Developers build interactive apps with Gradio, Streamlit, Docker, or plain HTML, then push their code to Spaces. Each push rebuilds and restarts the app automatically. Apps run on Hugging Face's cloud and get a public page anyone can try. A large public gallery lets you discover thousands of community-built demos, from chatbots to image tools. You can also duplicate any public Space with one click and remix it into your own.

Key Features

1. Free CPU hosting

Every Space gets 2 vCPU cores, 16 GB of RAM, and 50 GB of disk at no charge. This covers most Gradio and Streamlit demos.

2. GPU upgrades

Need more power? Rent GPU hardware by the hour, from Nvidia T4 cards up to A100 accelerators. Hardware is changed in the Space settings.

3. Push-to-deploy

Your Space is a git repository. Every commit you push triggers an automatic rebuild and restart, so updates go live without manual steps.

4. Public gallery

Published Spaces appear in a searchable public gallery. Anyone can run your demo from a link, which makes sharing work simple.

5. Private Spaces

Mark a Space private to hide it from search and the public. Private Spaces need a Hugging Face Pro account.

6. Community GPU grants

Builders with standout Spaces can apply for GPU grants to cover hardware costs. Hugging Face reviews applications in the Space settings.

Frequently Asked Questions (FAQ)

How much do GPU Spaces cost?

GPU hardware is billed by the hour. Prices start around 40 cents per hour for a small Nvidia T4, 80 cents for an L4, and one dollar for an A10G. A single A100 runs about two dollars and fifty cents per hour, and the largest multi-GPU setups reach twenty dollars per hour.

Do my files survive a Space restart?

No. The default 50 GB disk is temporary and resets when the Space restarts. Add paid persistent storage or save data to an external database if you need it to last.

Do I need to know Docker to use Spaces?

No. Gradio and Streamlit SDKs only need Python, and the static SDK only needs HTML. Docker is there if you want full control over the environment.

Can teams use Spaces together?

Yes. Spaces live inside Hugging Face organizations, where you can invite teammates and set roles. Organizations are handy for companies shipping demos or internal tools.

Conclusion

Hugging Face Spaces makes publishing an AI demo as easy as pushing code. The free CPU tier covers most small apps, and hourly GPUs scale up when models get heavy. For researchers and builders who want feedback fast, few platforms match its mix of free hosting, instant deploys, and a built-in audience of curious users.
