OpenAI Agents SDK
OpenAI's production-ready successor to Swarm — agents, hand-offs, and guardrails
Verdict
The production evolution of Swarm. Same lightweight hand-off pattern, but with built-in tracing, guardrails, and sessions that make it viable beyond prototypes. Works with the Responses API and, via LiteLLM-style adapters, other model providers. Good default for teams starting fresh on OpenAI-centric multi-agent work.
