• Core Question: Not just deciding which LLM to use, but determining how much computation to spend on that decision.
• Adaptive Routing Mechanism:
• Default to a cheap router.
• If confidence is low, invoke a more expensive/high-precision router for a second decision.
• Goal: Incur extra cost and latency only when it meaningfully improves the selection quality.
• Discussion: The author asks if this direction of "adaptive router complexity" already exists or represents a meaningful research gap.
