OpenAI Agents SDK
A lightweight SDK for agents, tools, handoffs, and traces.
Open source
Best when the team already standardizes on OpenAI models and wants the shortest path from prototype to observable agent workflow.
Official resources
Selection advice
Use it when provider alignment matters more than framework portability. Pair it with explicit evals before giving agents write access.
Best for
- OpenAI-first teams
- tool calling
- handoffs and traces
Not ideal for
- teams requiring model-neutral orchestration from day one
- deep graph state machines
Core concepts
agentstoolshandoffstracing
Minimal implementation shape
Define a small tool surface, run the agent with tracing enabled, then add handoffs only after the single-agent flow is reliable.
