In depth
A coordinator does not do the actual work itself. It reads the goal, writes a plan, spawns specialists in parallel, waits for results, then chains follow-up agents (a writer, an editor) to produce the final output. Running the coordinator on a premium model and the workers on a cheap model is the single biggest cost lever in agent design.
