What is LLM Routing?
LLM Routing is the technique of automatically directing queries to the most appropriate AI model based on task complexity, required quality, and budget. Instead of sending every query to the most expensive model, the router analyzes content and selects the optimal target.
How does multi-tier routing work?
The system classifies incoming queries and routes them to the appropriate tier. Simple FAQ questions go to fast, cheap models. Medium-complexity tasks are handled by mid-tier models. Only truly complex problems requiring deep reasoning reach the most expensive premium models.
Cost savings
Multi-tier routing can reduce API costs by 60-80% without quality loss. The key is proper classification — the system must recognize that "what's the weather?" doesn't require the same model as "prepare a due diligence analysis."
