Run Slow LLM Jobs Without Blocking FastAPI: Celery + Redis in Python

About this lesson

Slow LLM jobs should not hold your FastAPI request hostage — learn how to offload long-running model calls to background workers. Queue slow LLM calls, return immediate job IDs, and poll status to keep FastAPI responsive using Celery, Redis, and Pydantic. See retry/backoff strategies, progress metadata, and an integration test pattern that proves the loop without Redis.
