Prompt Chain Design Patterns: Sequential vs Conditional vs Parallel

Sequential, conditional, and parallel are the three prompt chain topologies — this guide covers how each one actually behaves and how to pick between them.

Solid purple cover graphic for the AI agent definition post

What Is an AI Agent? (And How It Differs From a Prompt Chain)

An AI agent decides its own next tool call turn by turn, within a hard per-turn cap — a prompt chain instead follows a fixed path you designed in advance.
