When Does LLM Orchestration Pay Off? A Controlled Evaluation of Accuracy, Cost, and Task Difficulty
Across five LLMs and three benchmarks, orchestration adds up to 4.6 points over optimized single-call CoT at 2-4x token cost, with no difficulty-scaled benefit but strong method-by-backbone interactions.
