Master OpenAI Agents SDK with our step-by-step tutorial, detailed feature walkthrough, and expert tips.
Explore the key features that make OpenAI Agents SDK powerful for ai agent builders workflows.
Built on just three core abstractions—Agents, Handoffs, and Guardrails—plus Python/TypeScript as the orchestration language. No custom DSLs or complex abstractions to learn.
A developer builds a multi-agent customer support system in an afternoon using standard Python patterns, without learning framework-specific concepts.
Agents can delegate tasks to specialized agents mid-conversation, with automatic context transfer and conversation continuity. Enables modular agent architectures.
A triage agent routes customer inquiries to specialized billing, technical support, or sales agents based on intent, with full conversation context passed through.
Input validation and safety checks run in parallel with agent execution rather than sequentially, with fast-fail behavior when checks don't pass.
A financial advisor agent validates user inputs for PII and checks output for compliance with regulations, all running concurrently with the main agent loop.
Built-in support for MCP (Model Context Protocol) server tools that work identically to native function tools, enabling agents to connect to any MCP-compatible tool ecosystem.
An agent connects to a company's internal MCP servers for database access, document retrieval, and API calls without custom integration code.
Persistent memory layer for maintaining working context within and across agent runs, enabling stateful conversations and long-running workflows.
A research assistant agent maintains context about a user's ongoing project across multiple conversation sessions over days or weeks.
Comprehensive tracing for visualizing and debugging agent workflows, with direct integration into OpenAI's evaluation, fine-tuning, and model distillation tools.
Using trace data to fine-tune a smaller model (GPT-4o-mini) to replicate the behavior of a more expensive agent (o3), reducing production costs by 90%.
The Agents SDK provides higher-level abstractions for agent loops, tool orchestration, handoffs between agents, guardrails, and tracing. The base API handles individual completions; the SDK manages the full agent lifecycle including multi-turn conversations, tool calling, and error recovery.
Yes. The SDK is designed to be provider-agnostic with documented paths for using non-OpenAI models. However, the best integration and feature coverage is with OpenAI's own models.
Yes. The Agents SDK is the production-ready successor to Swarm, which was an experimental research project. The SDK maintains Swarm's philosophy of minimal abstractions while adding production features like tracing, guardrails, sessions, and official support.
The SDK itself is free and MIT-licensed. You pay standard OpenAI API rates for model usage based on tokens consumed. Agent workloads typically use more tokens than simple completions due to tool calling loops and multi-turn conversations. Volume discounts are available for enterprise customers.
Yes. OpenAI provides both Python and TypeScript SDKs with equivalent functionality, making it accessible to both ecosystems. Install via pip (Python) or npm (TypeScript).
Now that you know how to use OpenAI Agents SDK, it's time to put this knowledge into practice.
