Loop Engineering vs. Graph Engineering , explained in plain English
People love throwing around these terms, but very few actually explain what they mean.
Think of loop engineering like one person solving problems step by step. They finish a task, check the result, decide what to do next, and repeat. Every decision is made inside the same working session, so all the context stays in one place. The downside? As that session grows, older details eventually get pushed out.
Graph engineering works differently. Instead of one person doing everything, the work is split into multiple stations. Each station has a single responsibility, and after every step the progress is saved. If something breaks halfway through, you restart only the failed step instead of rebuilding everything from scratch.
A simple way to choose between them:
-
Is this something you’ll repeat over and over? If it’s a one-off project, a loop is usually enough. Designing an entire workflow only pays off when you’ll reuse it many times.
-
Can success be checked automatically? Graphs shine when software can verify each step. If the final decision depends on human judgment or creativity, all those checkpoints don’t add much value.
-
Do you already know the exact workflow? If the process is still unclear, start with a loop. It can explore different paths and help you discover a workflow before you lock it into a graph. One thing many people misunderstand: loops haven’t disappeared. They’ve simply moved down a level. In most graph-based systems, every individual node is still running its own loop internally the graph just coordinates how those loops work together.
Save this for later, you’ll see these terms everywhere, but now you’ll actually know the difference.

Loop engineering is the practice of designing systems where AI agents autonomously decide what to work on, execute, and iterate, going beyond manual prompting by building outer loops that compound across different domains. The article explains the two-layer agent harness and how sharing artifacts between loops creates compounding learning.
