Which should you pick?

LangGraph is the one to pick for production work: it models agent runs as an explicit state graph, which means you can inspect, resume and reason about a run instead of hoping it terminates. CrewAI is the fastest to get something working, because role-and-task is an easy mental model. AutoGPT is the project that made autonomous agents famous and remains a good place to see the ideas, but it is more a platform than a library you embed.
