OpenAI Releases the Agents API in Public Beta
OpenAI announced the public-beta Agents API, a managed service that brings the Codex harness and supporting infrastructure to developers building cloud agents. Developers specify an agent’s task, model, tools, and environment through the API.
OpenAI says the public-beta Agents API brings the harness and infrastructure behind Codex to developers through a managed API. The announcement says developers can specify a task, model, tools, and environment, and can choose an OpenAI-managed sandbox, their own infrastructure, or supported sandbox partners. It also describes context compaction for long sessions, tool search, programmatic tool calling, and optional multi-agent support. The company says it operates and maintains the harness while developers retain control of their application’s tools, knowledge, and workflows.
