Taxonomy Surgery, Cosine = 1.0000, and Making Routing Disappear into Infrastructure
The author details the evolution of an adaptive model routing system, moving from an application-specific implementation to a more generalized infrastructure component. Initially, the system achieved 78.6% category accuracy, but upon realizing that two indistinguishable categories mapped to the same routing tier, the author merged them. This AI
IMPACT Refines LLM routing logic, potentially improving efficiency and cost-effectiveness by aligning taxonomy with model geometry.
