A step-by-step guide to building a hybrid AI workflow that routes complex reasoning tasks to DeepSeek-R1 and code generation to Claude Sonnet 4. The tutorial covers building a Node.js orchestration layer with Express, a complexity router using keyword heuristics, and a React frontend with dual-panel display. Key topics include cost optimization (R1 output tokens at $2.19/M vs Sonnet's $15/M), latency management with timeouts and fallbacks, structured JSON plan passing between models, and production hardening with rate limiting, structured logging, and retry logic.
