summary
Claims that multi-LLM setups outperform single models for evolving requirements and show three implementable patterns: static routing (UI components tied to one model), LLM-assisted classifier (route via a model that classifies prompts), and semantic embedding + vector DB (embed prompts and similarity-search against reference vectors). Notes practical tradeoffs: extra model calls raise cost and latency, caching can cut repeated inference, vector stores add complexity, and hybrid approaches balance accuracy, cost, and domain routing.
