Loop vs Graph Engineering: Clearly Explained! A loop is an autonomous cycle where an agent plans, acts, verifies the result, and keeps iterating until it reaches a stopping condition. The basic pattern is simple: Plan → Act → Verify → Repeat Loop engineering is about making that cycle reliable. You decide what context survives between iterations, how the agent evaluates its own work, when it should retry, how failures are handled, and what condition finally ends the run. This works well when one agent can own a coherent task from start to finish. The problem starts when the work itself becomes more structured. Some tasks need to happen in parallel. Different agents may need different context, tools, memory, or permissions. Certain steps may require human approval, while others can continue automatically. At that point, trying to force everything through one loop makes the system harder to reason about. That is where graph engineering becomes useful. A graph makes the workflow explicit. Nodes represent units of work such as agents, tools, validators, or deterministic functions, while edges define how state and control move between them. The important part is that loops and graphs are not competing architectures. A loop can itself be one node inside a larger graph. For example, a research agent may run its own Plan → Act → Verify loop, while a separate analysis agent runs another loop. A graph can then coordinate when those agents start, what context they receive, how their outputs are combined, and what happens next. So the practical distinction is: • Loop Engineering: design one autonomous execution cycle around a task • Graph Engineering: design how multiple execution cycles, tools, and decision points coordinate through shared state and explicit control flow You usually start with a loop when one agent can handle the task end to end. You move to a graph when the work needs parallel execution, specialized agents, different permissions, explicit branching, or clearer control over how state moves through the system. Graph engineering does not replace loop engineering. It becomes useful when one loop is no longer enough to hold the workflow together. I've shared the full article in the comments!
