Limits
AutoGen has no token or run allowance because it is a library. Cost comes from connected models, code sandboxes, hosting, and observability. The decisive fact is status: the official repository marks AutoGen as maintenance mode without new features and directs new users to Microsoft Agent Framework. AutoGen Studio is also a prototype and explicitly not production-ready. Existing projects have official migration samples to Agent Framework.
