Official docs for OpenAI's lightweight Python framework for multi-agent workflows.

Start LearningReviewed July 4, 2026

Overview

The OpenAI Agents SDK is a lightweight, Python-first framework — the production successor to OpenAI's experimental Swarm — for building agentic applications with very few abstractions. Its official documentation covers the core primitives: Agents (LLMs configured with instructions and tools), Handoffs (delegating work to other specialized agents), Guardrails (validating agent inputs and outputs), Sessions (persistent memory across turns), and built-in Tracing for visualizing and debugging agent runs. The SDK is provider-flexible — it works with OpenAI's Responses and Chat Completions APIs and many other models — and its documentation includes quickstarts, guides, and full API reference so engineers can go from a single agent to orchestrated multi-agent workflows.

What You’ll Learn

  • Define agents as LLMs configured with instructions and tools
  • Orchestrate multi-agent workflows using handoffs between specialized agents
  • Add input/output guardrails to validate and constrain agent behavior
  • Maintain conversation state with Sessions and debug runs with built-in tracing
  • Use the SDK across OpenAI and other model providers

Highlights

  • Official, actively maintained OpenAI documentation and API reference
  • Minimal-abstraction, Python-first design over the older Swarm project
  • Built-in tracing to visualize and debug multi-agent runs

Who It’s For

Best For

  • Python developers building production multi-agent systems
  • Engineers who prefer a thin framework over heavyweight orchestration
  • Teams wanting native tracing and guardrails for agents

Prerequisites

  • Intermediate Python
  • Familiarity with LLM APIs, tool/function calling, and async basics
