Covers a three-pillar routing model based on data sensitivity, task complexity, and system availability. The stack uses LiteLLM as a unified proxy gateway, Ollama for local model serving, Anthropic Claude as the cloud tier, LangChain for orchestration, and Next.js as the application layer. Includes full TypeScript code for routing logic, LangChain RunnableBranch chains, Next.js API route handlers with PII detection, LiteLLM YAML configuration, cost-benefit analysis with worked examples, Kubernetes deployment patterns (sidecar, dedicated GPU node pool, edge-local), and a production deployment checklist. Key architectural constraint: sensitive requests must fail closed and never fall back to cloud providers. ## Full article daily.dev links to this article rather than hosting it.
