fal
fal is a serverless Python runtime that lets you run and scale code in the cloud with no infra management.
With fal, you can build pipelines, serve ML models and scale them up to many users. You scale down to 0 when you don't use any resources.
For full product and platform documentation, see fal.ai/docs.
Quickstart

pip install fal

def run(self) -> dict:

Deploy it to a persistent endpoint:
