OpenAI Swarm
Lightweight experimental framework for agent hand-offs — superseded by the Agents SDK
Verdict
The educational precursor to the OpenAI Agents SDK, which now covers everything Swarm did plus tracing and guardrails. Still fine for reading through minimal, readable hand-off code, but new projects should start on the Agents SDK instead.
