Build with OpenAI Agents API on Vercel

Vercel pairs OpenAI-managed agent sessions with isolated, persistent Sandboxes, using signed webhooks and queues for reconnection and scaling workers to zero.

Source Summary

The integration runs long-lived, tool-using agents with an **OpenAI-managed loop and session state**, while Vercel hosts the app and attaches each session to an **isolated Sandbox** with persistent files. Signed webhooks and Vercel Queues handle creation and reconnection.

Practical Implication

Builders can separate agent orchestration from execution infrastructure: let OpenAI retain the session while Vercel provides code execution, file access, and a workspace that survives follow-up instructions. The worker architecture can scale to zero.

The material does not state persistence duration, sandbox limits, retry semantics, pricing, or recovery behavior when either provider is unavailable, so those boundaries need validation before production use.

This makes the brain-versus-hands split concrete across providers: OpenAI owns the durable loop and session, while Vercel owns isolated execution and persistent files. It reduces the custom machinery needed for long-lived agents and idle workers, but creates a cross-provider reliability boundary. Persistence, retries, recovery, limits, pricing, and partial outages therefore become production prerequisites rather than settled properties.

Scaling Managed Agents: Decoupling the brain from the handsAnthropic independently reinforces decoupling the agent harness from replaceable sandboxes, showing that the OpenAI–Vercel split is part of a broader managed-agent architecture pattern.Cursor Cloud Agents can now run in Vercel SandboxThe Cursor integration applies the same orchestration-versus-execution division to another managed agent, reinforcing portability of the pattern while exposing different access and lifecycle constraints.From fork() to Fleet: Designing an Agent Sandbox Cloud — Abhishek Bhardwaj, OpenAIOpenAI’s sandbox-cloud design supplies the isolation, snapshot, recovery, and placement concerns that this integration leaves unspecified and that must be validated for long-running sessions.Unlock Agent Autonomy: The Runtime for AI-Native Systems — Tushar Jain, DockerDocker’s external, task-scoped policy model highlights that attaching an isolated sandbox does not by itself define safe capabilities or authorization for the tools executed there.
