LLM Architecture: System Design for Production AI
Design decisions for production LLM systems — routing, cost, guardrails, and multi-model orchestration. The layer between running models and building reliable AI applications.

Cost Optimization for LLM Systems: Where the Money Actually Goes
Spend tokens where they actually matter.
LLM costs scale linearly with usage. A system processing 10,000 requests a day at $0.01 per request costs $100 daily — $365 a year. At enterprise scale, that’s over $10,000.
Model Routing: Stop Using One Model for Everything
The right model for the right task.
Running a 70B parameter model to summarize a 200-word email is wasteful. Running a 3B model to review production code is reckless. Most systems live somewhere in between — and that’s where model routing comes in.
