- In short
- The four workflow sub-patterns are prompt chaining (fixed sequential steps where each output feeds the next), routing (an initial classification sends the request down one of several fixed paths), parallelization (independent sub-tasks run concurrently and results are aggregated), and evaluator-optimizer (a generation step is checked by an evaluator step and refined until it passes). Each is a fixed, human-designed control flow suited to a different task structure.
