## A canvas for multi-step agents

**Agent Builder** is OpenAI's visual canvas for building **agent workflows**: you drag nodes (agents, tools, logic, data steps) onto a canvas, connect them, preview runs with traces, and **publish** a versioned workflow. It was introduced as part of OpenAI's **AgentKit** tooling alongside the **Agents SDK** (code library for agents), **ChatKit** (embeddable chat UI for workflows), a connector registry for tools and data, and **evals** for testing agents. A workflow can be called from your app by its ID or exported as Agents SDK code you host yourself. Product details such as node names and menus change; check the current OpenAI documentation.

## Canvas, code and deployment

A visual builder lets you design multi-step agent workflows, test them and publish versions that apps can call.

## A flowchart that actually runs

Teams have always drawn agent flows on whiteboards. A workflow builder makes the drawing executable: each box is a real step and each arrow a real transition.

## Treat the canvas as a design and test tool

Even if production runs in code, sketching and previewing the flow on a canvas is a fast way to agree on behaviour with non-developers.

**Quiz:** What is Agent Builder?

- [ ] A vector database
- [ ] A model training service
- [x] A visual canvas for designing, testing and publishing agent workflows
- [ ] A replacement for HTTP

*Answer:* A visual canvas for designing, testing and publishing agent workflows. It composes agents, tools and logic into versioned workflows.
