Context

OpenAI's Agents API is a managed service powered by the Codex , the orchestration software behind Codex, for developers building cloud agents. In its September 10, 2026 announcement, the company describes a public beta that manages , and coordination for extended tasks.

The agent's execution environment remains a separate choice: developers can use an OpenAI-hosted sandbox, their own infrastructure or a supported partner. That separation lets a team use the managed coordination system while choosing where files and code execution live. The service supplies a common operating layer while developers provide their application's tools and workflows.

Terms in this piece · Glossary

agent harness — The scaffolding around a model that turns it into a working agent — the loop, the tools it can call, and the rules for when to stop.
context window — The maximum amount of text a model can consider at once — its working memory for the current conversation or task.
tool use — A model's ability to call external functions — run code, search the web, edit files — instead of only generating text.
multi-agent — Using several AI agents on one problem — splitting work in parallel, checking each other, or filling different roles like planner and reviewer.
