OpenAI Swarm
OpenAI's educational multi-agent framework. Minimal, opinionated, not production-hardened.
By C.W. Jameson · Published 19 May 2026 · Last reviewed 19 May 2026
Swarm is the framework OpenAI released to demonstrate their preferred mental model for multi-agent systems: lightweight, stateless agents that hand off tasks via a transfer mechanism. OpenAI explicitly labelled it educational rather than production. Nonetheless it influenced the architecture decisions of several operator frameworks, and its minimalism was a corrective to LangChain's complexity.
Field signature
Agent handoff via transfer_to_agent() function call.
