The Hidden Cost of Running AI Applications in Production
The token price didn't change between prototype and production. The architecture did. Where AI app costs really come from, and how to cut them.
Practical AI engineering — how AI systems are designed, built, debugged and shipped. Guides, architecture, experiments and production lessons.

Non-deterministic output, hidden prompts and multi-step pipelines make AI bugs hard to reproduce. A systematic approach that turns 'it gave a weird answer' into a fix.
