OpenAI has announced the Agents API, a managed service designed to let developers build and launch cloud agents. The company says the offering is powered by the Codex harness, the underlying system responsible for agent orchestration.
According to the announcement, the API supports three core capabilities: orchestration of agent workflows, long-running sessions, and tool use. Together, these features are aimed at teams that want to run agents in the cloud without managing the underlying infrastructure themselves.
By packaging these capabilities as a managed service, OpenAI positions the Agents API as a way for developers to move from prototypes to deployed cloud agents more directly. The company did not disclose pricing, availability dates, or benchmark results in the announcement text.
