situationalOfficial Python agents runtime — agents, handoffs, guardrails, sessions; not the Responses API itself.

The runtime on top of Responses, not a second Responses card. Tiny primitives (agent, handoff, guardrail, session) plus sandbox and realtime paths. You own orchestration less than with raw Responses, more than with a visual builder. Tokens still land on the API bill.
Strengths
- Official Python agents runtime with tiny, composable primitives.
- Agent, handoff, guardrail, and session abstractions out of the box.
- Includes sandbox and realtime paths beyond basic chat loops.
Known limitations
- Default loop talks to OpenAI; other providers are possible but second-class.
- Built-in tracing is convenient and also a data-boundary choice.
- Not a no-code product; you write Python.
- Swarm is the old experiment — this SDK is the replacement.
Use it when
- Python developers building agents on top of the OpenAI Responses API.
- Teams wanting more orchestration than a no-code builder but less than raw API code.
Skip it when
- You need a visual no-code interface for building agents.
- First-class non-OpenAI providers are a hard requirement.
- Built-in tracing sending data to OpenAI is a data-boundary problem.
Buy-check
- ·Price — free, SDK free (pip install openai-agents); model/tool calls billed at OpenAI API rates; tracing uses your OpenAI account as of 2026-08-19. Open the pricing page, not a screenshot.
- ·Free tier — Free tier exists — burn it first.
- ·Cancel fallout — What happens to your data/projects on cancel — check the ToS, not the FAQ.
- ·Seat math — Per-seat pricing multiplies quietly. Count seats before the annual plan.
- ·Who skips it — Also skipped when: You need a visual no-code interface for building agents.; First-class non-OpenAI providers are a hard requirement..
