Decoding AI’s Open-Source Course Maps Three Ways to Run an Agent Loop and the Provider Economics Behind Each

LangChain’s Terminal-Bench experiment found that swapping the agent harness while keeping the same model can move a coding agent from about 30th place to the top 5. The article describes three agent-loop run modes—interactive, remote/offline, and async/online—each with different latency behavior that maps to different inference providers and billing goals. As a result, teams should treat loop execution details as an architecture choice with distinct provider economics, and the open-source Decode framework organizes its agent into a shared core plus three harness shapes.
