The OpenAI Agents SDK is a lightweight yet powerful framework for building multi-agent workflows in JavaScript/TypeScript. It is provider-agnostic, supporting OpenAI APIs and more.

1. Agents: LLMs configured with instructions, tools, guardrails, and handoffs
2. Agents as tools / Handoffs: Delegating to other agents for specific tasks
3. Tools: Various Tools let agents take actions (functions, MCP, hosted tools)
4. Guardrails: Configurable safety checks for input and output validation
5. Human in the loop: Built-in mechanisms for involving humans across agent runs
6. Sessions: Automatic conversation history management across agent runs
7. Tracing: Built-in tracking of agent runs, allowing you to view, debug and optimize your workflows
8. Realtime Agents: Build powerful voice agents with full features

npm install @openai/agents zod

import { Agent, run } from '@openai/agents';

const agent = new Agent({
  name: 'Assistant',
  instructions: 'You are a helpful assistant',
});

const result = await run(
  agent,
  'Write a haiku about recursion in programming.',
);
console.log(result.finalOutput);
// Code within the code,
// Functions calling themselves,
// Infinite loop's dance.

(If running this, ensure you set the OPENAI_API_KEY environment variable)

We'd like to acknowledge the excellent work of the open-source community, especially:

• zod (schema validation)
• Starlight
• vite and vitest
• pnpm
• Next.js

We're committed to building the Agents SDK as an open source framework so others in the community can expand on our approach.
