Traditional automation follows fixed rules. If X happens, do Y. Reliable — but brittle. It breaks the moment reality doesn't match the script.
An AI agent is different. It reasons about a goal, plans a sequence of steps, executes tools and APIs, interprets the results, and adjusts its approach — all without a human managing each decision.
The distinction LangGraph draws is precise: a workflow is a defined graph of steps. An agent uses an LLM to decide which steps to take next. Both have their place. We build both — and we know when each is the right choice.
