Orchestrator-Workers Pattern

Definition

A workflow composition pattern where a central LLM decides subtasks dynamically at runtime and delegates them to workers, in contrast to parallelization sectioning where the subtasks are already known in advance. It is still a workflow, not an agent, as long as the fact that delegation happens is fixed in code -- only the content of the subtasks is decided at runtime. This is the point where a workflow shades most closely into an agent, and the classic exam trap is confusing it with parallelization sectioning.
