How to choose
For agent-behavior research and flexible conversation patterns (group chat, nested chats): AutoGen — more flexible abstractions with a rich paper ecosystem. For production business apps and fast delivery: CrewAI — the role-division model is easier to understand and debug, with engineer-friendly docs. Both support major models; beginners ramp up faster on CrewAI, researchers prefer AutoGen's flexibility.
