OpenAI Launches Managed Agents API for Cloud-Based AI Agents
OpenAI has introduced an Agents API designed to simplify the development of cloud-based AI agents. The new offering is a managed service built around a Codex harness that handles the core orchestration logic, enabling developers to focus on agent behavior rather than infrastructure.
The API supports long-running sessions, allowing agents to maintain context and state across extended interactions without requiring developers to manage session lifecycle themselves. Tool use is also a first-class feature, enabling agents to call external functions and services as part of their reasoning loops.
By packaging orchestration, session management, and tool integration into a single managed API, OpenAI aims to lower the barrier for developers looking to deploy production-ready agents at scale.
