CTO Cuts AI Chatbot Costs by 65% With Multi-Model Routing

A CTO reduced inference costs by 40-65% by replacing a single GPT-4o setup with a multi-model routing system using DeepSeek, Qwen, and GLM-4 models. The system routes 80% of queries to cheaper models while reserving expensive models for complex tasks. The architecture uses a model-agnostic API layer to avoid vendor lock-in.
