Introducing the Agents API
OpenAI has launched the Agents API, a managed service designed for building and deploying cloud-based agents. The service utilizes the Codex harness to provide orchestration, persistent long-running sessions, and integrated tool use capabilities.

Impact & Verification Analysis
Software developers, enterprise AI engineers, and platform architects building autonomous agentic systems.
This release lowers the barrier to entry for deploying complex, stateful AI agents by offloading infrastructure management to OpenAI, potentially accelerating the adoption of agentic workflows in production environments.
Full Fact Overview
The Agents API represents a shift from stateless request-response interactions to stateful, autonomous agentic workflows. By leveraging the Codex harness, OpenAI is abstracting the complexity of managing agent state, memory, and tool execution environments. This managed service architecture suggests a move toward providing infrastructure-as-a-service for agentic systems, reducing the overhead for developers who previously had to implement custom orchestration layers for long-running tasks.
