Overview

OpenAI Agents SDK provides agents with tools, handoffs, guardrails, sessions, and tracing.

It integrates with the OpenAI API and Responses API.

The Agents API (public beta, 2026-09-10) is a separate hosted Codex harness for durable cloud-agent sessions—OpenAI-hosted or self-hosted sandboxes, context compaction, and recovery. It is not ZDR-eligible. Use the SDK when you own the loop; use the Agents API when you want OpenAI to run the harness.
