"Agents" are the most hyped word in AI right now, and that hype is pushing teams to build autonomous, self-directing systems for problems a simple pipeline would solve better. Both approaches use LLMs; they differ in who's in control. Choosing correctly is one of the highest-leverage decisions in an AI feature — it determines your reliability, cost, and how much you'll debug at 2am.

The difference isn't intelligence; it's **who decides the next step.**

Workflows are predictable and cheap. Agents are flexible and open-ended, but harder to control, more expensive, and slower.

For the vast majority of product features, **a deterministic workflow is the right choice.** If you can describe the steps in advance — and usually you can — then hard-coding them gives you enormous advantages:

Most "agent" demos are really a fixed three-step pipeline dressed up in autonomy. Just build the pipeline. A chain of well-defined LLM calls, orchestrated in **TypeScript** with validation between steps, handles an astonishing range of real features.

Reach for a true agent only when the problem has these properties:

Research assistants, complex data investigations, and open-ended coding tasks can justify agents. A support responder or a document summarizer almost never does.

You don't have to choose purely. The best-designed systems are **mostly workflow with a small agentic core** exactly where flexibility is needed. Structure the overall flow as deterministic steps, and let the model make bounded decisions only at the point that truly requires judgment — with guardrails around it.

Whatever you choose, constrain it:

Start with a workflow. Add autonomy only where a workflow provably can't do the job — and you'll ship something more reliable and far cheaper than the agent everyone told you to build. If you're weighing the two for a real feature, [let's talk](https://dev.to/#contact).
