OpenAI Agent Builder: Visual canvas from OpenAI’s AgentKit — being retired on 30 November 2026.

OpenAI Agent Builder is a visual canvas for multi-agent workflows launched with AgentKit on 6 October 2025 — and it is being retired. OpenAI’s update of 3 June 2026 says Agent Builder and Evals will no longer be available from 30 November 2026; OpenAI recommends the Agents SDK for code-based workflows and Workspace Agents in ChatGPT for natural-language use cases.

What is OpenAI Agent Builder?

Agent Builder offered drag-and-drop nodes, tool connections, guardrails, preview runs and versioning, alongside ChatKit for embedding chat agents. With the shutdown date set, teams should plan migrations now.
