Getting Started with OpenAI Agent Builder: Build Multi-Agent Workflows with Drag-and-Drop Interface

📘 Introduction

Welcome to this hands-on guide to OpenAI Agent Builder — a revolutionary no-code tool that lets you design and deploy multi-agent workflows using a drag-and-drop interface. In this post, we’ll walk you through how to access the Agent Builder and create your first agent workflow step-by-step.

💡 What is OpenAI Agent Builder?

Agent Builder is part of OpenAI’s AgentKit, a new suite of tools that makes it easy to create, manage, and deploy AI agents — all within the OpenAI platform.

At its core, Agent Builder is a no-code, drag-and-drop interface with a visual canvas where you can design intelligent workflows. Instead of writing complex scripts, you can visually connect GPT-powered agents, tools, and data sources directly on the canvas — making it simple to design and understand how your AI system works.

With Agent Builder, you can:
🤖 Build intelligent agents powered by GPT models
🔗 Connect them to APIs, databases, or custom tools
🧠 Combine multiple agents into collaborative workflows
🎨 Design visually on an intuitive canvas
⚙️ Deploy and manage everything directly from the OpenAI platform

✅ Prerequisites

Before getting started, make sure you have:

👤☑️ An OpenAI platform account
