Graph Engineering vs Loop Engineering: One Agent's Cycle vs a Graph of Specialized Nodes
Overview Loop engineering designs a single agent’s operational cycle — discover, plan, execute, verify, repeat — where the real bottleneck is the verifier, not the prompt. Graph engineering wires multiple specialized agents or steps into a directed graph of nodes and edges, so work can fan out in parallel and fan back in. As aibuilderclub.com frames it, this isn’t new technology — LangGraph, AutoGen, and Google’s ADK already did this — so much as a name for the moment composing loops into an org-chart-like structure actually earns its added complexity. ...
