Description
OpenAI's managed version of the Codex harness to build cloud agents with one API call instead of your own orchestration. Handles long sessions, smart tool use, and subagents working in parallel. Runs on OpenAI or partner sandboxes. No extra fees beyond token and tool usage. Open source harness, public beta now.

Could you build this?
No Providing a high-reliability, multi-tenant cloud agent execution platform with distributed state management, sandboxed execution environments, and sub-agent parallel orchestration requires deep distributed systems and virtualization infrastructure.
What it would actually take: This requires a robust container/microVM orchestration layer (such as Firecracker or gVisor) running across large GPU/CPU clusters with strict sandboxing and minimal cold starts. The system must support long-lived resumable sessions, stateful snapshotting, secure socket tunneling for tool access, and sophisticated distributed scheduling to handle recursive agent delegation safely.
