Model Routing System

How Routing Decisions Are Made

Every user prompt goes through a 9-tier classification pipeline before any AI model processes it. The system answers three questions:

1. Which model should handle this? — 9-tier cost/complexity classification
2. Is the classifier itself working? — Cascading fallback (qwen3 → kimi → deepseek → cache)
3. Can we verify the result? — Tool-level fallback + auto-evaluation
