Hugging Face: Deploy ML Demos Free (2026)

⚡ VERDICT

Best for: Developers and data scientists who want to share a quick ML demo without managing servers or containers.

Skip if: You need GPU inference for large models, custom networking, or persistent storage beyond the free tier.

Price: Free tier available; GPU Spaces from $0.40/hour (checked 2026-10-15)

Skill level: Beginner

Time to first result: [TODO: our test] measure, don't estimate

Score: [TODO: our test] measure, don't estimate

🚀 Quick start

Create a free Hugging Face account and go to Spaces.
Pick Gradio as the SDK for the fastest path to a working UI.
Paste a short Python script that loads a pre-trained pipeline.
Commit the file and wait for the Space to build and run.

💡 Why use Hugging Face for this

Hugging Face Spaces lets you host interactive machine learning demos directly from a Git repository. You pick a framework (Gradio or Streamlit), write a small Python script, and the platform builds and serves a public URL. The free tier runs on CPU-only hardware with 2 vCPU and 16 GB RAM, which is enough for small models like BERT or ViT but not for large language models or image generators. Paid GPU Spaces start at $0.40/hour for a T4 and go up to $4.50/hour for an A100. This guide walks through creating a sentiment analysis demo using a pre-trained pipeline from the Hub.

🛠️ How to Deploy ML Demos Free (5 steps)

Step 1

Go to huggingface.co/spaces and click the 'Create new Space' button. .

Step 2

Enter a name for your Space (e.g., 'sentiment-demo'), set the License to 'MIT', and under 'Space SDK' select 'Gradio'. Click 'Create Space'. .

Step 3

In the file editor, open 'app.py', delete the default content, and paste the sentiment analysis code. .

Step 4

Click 'Commit' at the bottom of the editor, add a commit message like 'Initial sentiment demo', and confirm. .

Step 5

Wait for the Space status to change to 'Running' (typically 1–2 minutes). .

📦 What you'll get

You get a public URL like https://huggingface.co/spaces/your-username/sentiment-demo that hosts a Gradio interface. Users can type text and receive a sentiment label with a confidence score.

📋 Copy-paste prompts

PROMPT 1 — Build a custom image classifier demo

"Write a Gradio app that loads the model 'google/vit-base-patch16-224' from Hugging Face Hub and accepts image uploads. Display top-3 predictions with probabilities."

PROMPT 2 — Interactive text summarizer

"Create a Streamlit app that uses 'facebook/bart-large-cnn' for summarization. User pastes a long article and gets a 3-sentence summary with a slider to control max length."

PROMPT 3 — Zero-shot audio classification

"Build a Gradio interface that takes an audio file and labels it using 'facebook/wav2vec2-base-960h' for speech-to-text, then a zero-shot classifier. Show both the transcription and the predicted label."

⚠️ Common mistakes

❌ Using a model that requires GPU on the free tier.

Why it happens: Large LLMs or image generation models exceed free CPU resources.

✅ Quick Fix: Stick to small models (BERT-sized or smaller) or upgrade to a paid GPU Space.

❌ Forgetting to pin the versions of libraries in requirements.txt.

Why it happens: Spaces rebuild sometimes break due to updated packages.

✅ Quick Fix: Always include `gradio==X.X.X` and `transformers==X.X.X` in requirements.txt.

❌ Committing a Python file with syntax errors.

Why it happens: The app.py is run on the server and fails silently.

✅ Quick Fix: Test your code locally first or use the built-in 'Check' button to catch syntax errors before commit.
