OpenAI Agents SDK JS

OpenAI Agents SDK JS is a lightweight framework for building multi-agent workflows and voice agents in JavaScript and TypeScript.

The OpenAI Agents SDK is a framework for building multi-agent workflows using JavaScript and TypeScript. It is provider-agnostic and supports OpenAI APIs and more. Developers can configure agents with instructions, tools, guardrails, and handoffs, or build sandbox agents paired with a filesystem workspace. It also supports real-time agents for low-latency spoken interactions in the browser. Features include automated conversation history management, built-in tracing, and human-in-the-loop mechanisms. The SDK runs in environments like Node.js, Deno, Bun, and Cloudflare Workers.
