In this video, I evaluate the new Agent Builder from OpenAI and clarify the key differences between simple workflows, augmented LLMs, and true autonomous agents. I'll show you why this new tool doesn't necessarily make platforms like n8n obsolete, as they serve different purposes.
I then provide a complete, step-by-step guide on how to create your own custom document-fetching agent. I demonstrate how to use the File Search tool by uploading a research paper and how to design a custom output using OpenAI's new widget creator. To bring it all together, I show you how to integrate this agent into a custom chatbot interface built with Next.js and Claude Code, deploying the Agent SDK to create a functional app.
