Building agents with OpenAI and Cloudflare’s Agents SDK

This post details the integration of OpenAI's Agents SDK with Cloudflare's Agents SDK, which leverages Durable Objects for persistent execution. It explains the separation of concerns (OpenAI for cognition, Cloudflare for execution environment) and demonstrates architectural patterns for building AI agents: multi-agent systems, human-in-the-loop workflows, and addressable agents. Key learnings include the importance of state management with Durable Objects, correct routing for agent identity and persistence, and the composability of agents.
