What is OpenAI Agents SDK?

The OpenAI Agents SDK is a lightweight package for building agentic AI apps with few abstractions, and is a production-ready upgrade of the earlier experimental project Swarm. It is built from a small set of primitives: agents equipped with instructions and tools, handoffs that pass work to other agents, and guardrails that validate inputs and outputs. Built-in tracing lets you visualize, debug, and evaluate agent flows. It supports the OpenAI Responses and Chat Completions APIs as well as more than 100 other LLMs.

  • Agents with instructions, tools, guardrails, and handoffs, plus a built-in loop
  • Sandbox agents that run in an isolated workspace
  • Real-time voice agents and voice pipelines (STT→agent→TTS)
  • Using agents as tools and delegating work through handoffs
  • Guardrails for input validation and safety checks
  • Function tools that turn Python functions into tools, and MCP tool calls
  • Session-based conversation history management
  • Built-in tracing and human-in-the-loop

Combos that work well with OpenAI Agents SDK

Source-tracking pricing update agent

OpenAI Agents SDKn8n

Agents split collection, field extraction, change comparison, and review requests by role. n8n orchestrates the input, output, retries, and approvals of each step and reads API keys from a secure credential store. Automation success is managed not by the volume published but by source completeness, approval rate, and error correction time.

Cost: Agents SDK open source, connected LLM API and n8n usage billed separately
