AI Engineering Concepts
A connected set of chapters on how LLM applications actually work — tokens, context windows, prompt budgets, agent loops. Every chapter pairs a short text with an existing tool you can change inputs on and watch the result.
The chapters run in order, starting from the questions that block people who are building with LLMs for the first time. Each chapter embeds the same tool you can find elsewhere on this site, so you learn by changing the input rather than by reading a summary.
