M-058Build an Intelligent Model Router
Description
Nebula Corp's AI platform sends every request to GPT-4o, costing a fortune. Most requests are simple FAQ lookups that a cheaper model could handle. Build an intelligent router that classifies request complexity and routes to the appropriate model tier: 'fast' (cheap model for simple tasks), 'balanced' (mid-tier for moderate tasks), or 'powerful' (expensive model for complex reasoning). The router should analyze the user message and return the correct model name.
