Free AutoGen Agent Hosting on Hugging Face Spaces

Deploy AutoGen agents on Hugging Face Spaces for free without juggling servers. This tutorial walks you through the entire setup in minutes.

What You’ll Need

• Hugging Face account (free tier)
• Python 3.9+
• Basic AutoGen script

Step‑by‑Step Deployment

1. Create a new Space: choose "Static UI" and give it a name like autogen-agent.
2. In the Space file explorer, add three files: app.py, requirements.txt, and README.md.
3. Paste the code snippets below into the respective files.
4. Commit changes; the Space builds automatically and provides a public URL.

Quick Reference
Copy this configuration to your Space root folder.

# requirements.txt
autogen==0.2.3
fastapi
uvicorn[standard]

# app.py
from fastapi import FastAPI
from autogen import Agent

app = FastAPI()

agent = Agent(name="demo", llm="gpt-3.5-turbo")

@app.get("/run")
def run_agent(prompt: str):
    response = agent.run(prompt)
    return {"prompt": prompt, "response": response}

if __name__ == "__main__":
    import uvicorn
    uvicorn.run(app, host="0.0.0.0", port=7860)

Configure the Space Runtime

Add a .huggingface config to set the start command. This ensures the app launches correctly.

# .huggingface.yaml
runtime: python
python_version: "3.9"
start_script: uvicorn app:app --host 0.0.0.0 --port $PORT

Testing the Deployed Agent

• Open the Space URL.
• Append /run?prompt=Hello+world to the URL.
• See the AutoGen response instantly.

Best Practices for Mobile Users

• Use concise prompts (< 100 characters) to keep latency low on mobile networks.
• Enable CORS in FastAPI if you call the endpoint from a mobile web app.

FAQ

Is the free tier enough for production?

For low‑traffic demos and prototypes, yes; the free tier provides 30 GB storage and 2 GB RAM.

Can I use a custom domain?

Yes, link a domain via the Space settings under “Custom domain”.

What if my agent needs GPU?

The free tier doesn’t include GPUs; upgrade to a paid Space or switch to a cloud GPU service.

Bottom Line

Hugging Face Spaces gives you a zero‑cost, no‑ops path to host AutoGen agents. With a few files and a simple config, you get a public endpoint ready for mobile integration.
