OpenAI Agents API

Bêta

OpenAI's managed Codex harness, exposed as an API for long-running agents

Visiter le site
Conditionnel

OpenAI's Agents API is the runtime OpenAI itself rates lowest in integration effort of the three it compares: it exposes the managed Codex harness with durable sessions, context compaction, subagents and hosted or partner sandboxes, and charges no fee beyond tokens, tools and container time. Conditional because it is a public beta that currently offers US-only data residency and no Zero Data Retention. Right for product teams already building on the OpenAI API; wrong for workloads that require ZDR or data residency outside the US.

OpenAI runs the agent loop on its infrastructure: a managed Codex harness drives model calls, tools and sandbox commands in durable sessions

Est-ce fait pour vous ?

Recommandé pour

  • Long-running tasks where OpenAI manages the agent and saves its progress, which is the use OpenAI's runtime comparison assigns to the Agents API
  • Shipping an agent without building the loop: OpenAI handles session orchestration, context compaction and recovery on its own infrastructure
  • Code execution and file work in an OpenAI-hosted sandbox, in your own infrastructure, or with a partner sandbox such as E2B, Modal, Daytona or Vercel
  • Extending agents with your own tools and MCP servers, plus skills loaded from the environment
  • Splitting complex work across subagents, which OpenAI's docs describe as breaking work into subtasks and delegating to subagents
  • Teams already on OpenAI API billing, since OpenAI says there are no additional fees beyond the tokens and tools agents use

Déconseillé pour

  • Workloads that require Zero Data Retention, which the Agents API currently does not support
  • Data that must stay outside the United States, since data residency is currently supported only in the US
  • Production systems that cannot absorb beta changes: it launched as a public beta and every request requires the OpenAI-Beta: agents=v1 header
  • Keeping the agent loop inside your own application, a use OpenAI's runtime comparison assigns to the Agents SDK, which runs inside your application
  • Budgeting from token prices alone, since OpenAI-hosted sandboxes bill separately at standard container rates

Recettes de flux de travail

Run a first agent session

Start one agent session in an OpenAI-hosted sandbox following OpenAI's quickstart

  1. Create an application API key in your OpenAI Platform project with api.agents.read, api.agents.write and api.responses.write
  2. Keep the key outside the agent's sandbox and export it as an environment variable
  3. Install the SDK with pip install --upgrade openai or npm install openai
  4. Create a session with an agent configuration, environment type openai_hosted and your input instructions, sending the OpenAI-Beta: agents=v1 header
  5. Stream session events, wait for agent.session.turn.completed, then check the agent's reported execution result
  6. Save the session_id to continue the work, or delete the session when finished
