OpenAI Splits Its Agent Harness From Compute, Opens Runtime to Cloudflare, Modal, and Vercel
What Happened
OpenAI separated its agent orchestration layer from compute and storage, releasing an open-source harness with file and computer-use primitives plus persistent memory. Launch partners include Cloudflare (Project Think, Agent Lee), Modal, and Vercel, who now provide the sandboxed execution environments.
My Take
This is the quiet shot at AWS's dominance in AI hosting. By making the agent the unit of deployment — not the container — OpenAI is betting the next cloud battle is fought above the VM layer. For CTOs, this rewrites the build-vs-buy calculus: agent harnesses are becoming commoditized plumbing, and the defensible layer is your proprietary tool catalog and business-rule memory. The companies that win the next 18 months will be the ones that treat "our agent tools" the way 2015 companies treated "our API."
