What are the best Python AI agent frameworks in 2024?

LangGraph and CrewAI. They aced real-world tests; others crumbled.

LangGraph vs CrewAI: which should I use?

LangGraph for complex, custom flows. CrewAI for quick multi-agent teams.

Not fully — but they'll wrap 'em smartly, saving you boilerplate hell.

Six Python AI agent frameworks entered. Two survived. Here's why the others bombed — and what that means for your next project.

Only LangGraph and CrewAI survived rigorous testing of six Python AI agent frameworks. 𝕏
Avoid PydanticAI, Smolagents, OpenAI SDK, and Google ADK for production agents. 𝕏
Bet on consolidation: these two will dominate like PyTorch did for DL frameworks. 𝕏
