Routing Models Efficiently Won't Solve LLM's Understanding Problem
Source: Bytebytego
The article frames smarter routing between smaller and larger models as a path to 10x cost reduction. That framing assumes compute waste is the bottleneck. The actual constraint—buried in the piece—is that access to more data, tools, and context windows doesn't create genuine comprehension. Agents become information retrieval systems with better filtering, not thinking systems. Organizations chasing cost optimization through routing may find themselves with cheaper but structurally incapable systems. The tension between expense and capability can't be simply engineered away.
