Three frameworks, three mental models. When to use each and why — with a real orchestration case.
OpenAI published Swarm as an experimental, educational framework for multi-agent systems. It reduces coordination to two concepts — agents and handoffs — and fits in under 500 lines of Python. A comparison with CrewAI and LangGraph.
CrewAI models agents as a team, each with an explicit role and a set of tasks to carry out. How it compares with LangGraph and AutoGen, what the multi-agent pattern really costs to run, and when the extra coordination is worth paying for.
