Comparing
Distributed task queue for async and scheduled background jobs in Python.
Official Python SDK for the OpenAI API — call GPT-4, DALL-E, Whisper, and Embeddings with a clean async-first interface.

Sending emails or notifications, processing uploads, running scheduled cron-style jobs, chaining multi-step workflows, fan-out parallel processing.
Integrating GPT-4/3.5 into apps, generating embeddings for semantic search, transcribing audio with Whisper, generating images with DALL-E, or building agentic workflows with tool calling.
Simple scripts that don't serve web traffic — just use asyncio or threading. If you need sub-millisecond latency, Celery's overhead is too high. For tiny projects, consider RQ (simpler) or FastAPI BackgroundTasks.
When you need to run models locally (use ollama or transformers), when cost is a hard constraint for high-volume tasks, or when you need a specific open-source model.
