What Is OpenAI Agents SDK?
The OpenAI Agents SDK is a lightweight Python framework for multi-agent workflows. The official docs list its core building blocks as agents, agents-as-tools and handoffs, and guardrails, and the GitHub README describes agents as LLMs configured with instructions, tools, guardrails and handoffs. Handoffs let one agent delegate to another for specific tasks, and guardrails are configurable safety checks on inputs and outputs, which one guide describes as Python functions returning pass or fail. Built-in tracing visualises, debugs and monitors workflows, and one third-party guide says the tracing backend defaults to OpenAI's cloud but can point to a self-hosted endpoint.
The licence is listed as MIT by third-party sites, but it was not found in the official repo text retrieved here, so verify the LICENSE file on GitHub. One page says the SDK succeeded the experimental Swarm project and first released in March 2025, and another says a 2026 update added sandbox agents for long-running tasks in isolated containers, but neither is confirmed by official pages. The SDK itself is free; you pay for model usage through your provider, and other providers can be used per third-party guides.
The Agents SDK suits developers who want a small, readable set of primitives rather than a heavy framework. Compare LangGraph, CrewAI and Amazon Bedrock Agents. Browse the AI Agents & Automation tools directory for more.
