Pick LangGraph if its specific capabilities (Multi-agent, Tool use) match what you need. Pick OpenAI Swarm if its specific capabilities (Multi-agent, Tool use) match what you need. Most working teams running both can use LangGraph for primary work and OpenAI Swarm for the workflows where its specific strengths matter.
Both LangGraph and OpenAI Swarm start in the same pricing range (Free · OSS vs Free · OSS). Total cost of ownership depends on your team size and volume — see the TCO calculator for your specific math.
Both LangGraph and OpenAI Swarm are Autonomous agents — neither has a meaningful autonomy advantage over the other. The decision should hinge on capabilities and pricing instead.
