What each one is
AutoGen
AutoGen — the official full name, short for “Automated Generation” — is Microsoft’s open-source framework for building multi-agent AI systems where agents converse to solve tasks, with strong support for code execution and tool use.
- Flexible multi-agent conversation patterns
- Strong code-execution and tool-use support
- Backed by Microsoft Research
OpenAI Swarm
Swarm is a deliberately tiny framework showing how agents can hand off work to one another, built for learning rather than production.
- Extremely small and readable
- Clear handoff and routine patterns
- Great teaching material
