OpenAI introduces managed Agents API for cloud-based autonomous systems
A production service for long-running autonomous agents signals OpenAI's shift from models to deployed reasoning systems.
OpenAI has released the Agents API, a managed cloud service powered by its Codex harness for orchestration, long-running sessions and tool use. The API enables developers to build and deploy autonomous agents at scale.

What happened
OpenAI announced the Agents API, a managed service for building and launching cloud-based agents. The system uses the Codex harness for orchestration, supports long-running sessions, and enables tool use integration. It is available as a cloud service for developers.
Why it matters
This moves OpenAI from selling inference capability toward productising agentic workflows, positioning autonomous systems as a managed service rather than a developer toolkit. It signals the company's bet that the next phase of value lies in orchestration and persistence, not raw model access. Competitors will face pressure to match the operational infrastructure required to run agents reliably.
What changes
Developers can now deploy autonomous agents as managed services without building orchestration infrastructure themselves. The API abstracts session management, tool calling, and persistence, lowering the barrier to agentic product development.
