Model Routing and Cascades in Production: Comparing RouteLLM, FrugalGPT, Embedding Classifiers, and Verifier Cascades

Model Routing and Cascades in Production: Comparing RouteLLM, FrugalGPT, Embedding Classifiers, and Verifier Cascades Enterprise LLM deployments face a persistent structural inefficiency: the uniform routing of all incoming queries to flagship frontier models. Commercial API pricing and self-hosted GPU infrastructure costs span two orders of magnitude between lightweight models (such as Llama 3.1 8B, GPT-4o-mini, and Claude 3.5 Haiku at $0.15 to $0.30 per million tokens) and frontier reasoning
