OpenAI Launches Agents API — Managed Cloud Autonomous Workflows
OpenAI released the Agents API, a managed runtime enabling developers to run persistent, multi-step autonomous agents in isolated cloud sandboxes, with native support for sub-agent parallelization and long-context recovery. The launch formalizes the infrastructure behind Codex and brings it to enterprise developers.
- Purpose-built for durable agents: session persistence, tool-use approvals, and recursive sub-agent delegation handled server-side
- Built on the Codex execution harness; targets enterprise use cases requiring hours-long autonomous operation
- OpenAI simultaneously paused new Pro subscriptions due to capacity pressure from GPT-6 Astra demand
