Model serving

FastAPI is a modern, high-performance web framework for building APIs with Python.

Use it when

  • You want a simple syntax that makes creating endpoints fast.
  • You want to have automatic API docs based on Swagger or ReDoc.

Watch out

  • FastAPI does not provide model management features as dedicated model servers do, such as model versioning, scaling, and A/B testing.
  • FastAPI creates APIs, but it does not come with a webserver. You will need to deploy it with a Python webserver.

Example stacks

Airflow + MLflow stack


pip install fastapi
