Agentic Workflow vs. Autonomous Agent: What’s the Difference?

A conceptual and practical breakdown of the spectrum from deterministic workflows to autonomous multi-agent systems, anchored on a single axis: who owns control flow — a human writing code in advance, or a model reasoning at runtime. The piece walks through four stages (deterministic pipelines, orchestrated workflows, ReAct-based reactive agents, and autonomous multi-agent swarms) with illustrative code snippets showing how control flow differs at each stage. Key takeaway: in production, hybrid architectures dominate — deterministic modules handle well-understood steps while genuine autonomy is reserved for open-ended sub-problems. Fully autonomous agents remain largely exploratory outside narrow domains.
