Smart API Routing Slashes LLM Costs by 70%

This article reveals a critical gap in AI cost optimization: most developers focus on changing code or switching providers, overlooking architectural solutions that can deliver 70% savings instantly. By implementing an intelligent proxy layer that routes simple requests to cheaper models like Claude Haiku and complex ones to premium models like GPT-4, engineers can dramatically reduce LLM API expenses without any code changes. This approach fundamentally shifts how teams should think about infrastructure costs in AI applications.
