One lesson a day · Free
Each lesson is an animated video, a written deep dive with code that runs, and a quick quiz. Starting with System Design and AI Engineering, with more stacks on the way.

§ 01
Each domain is split into subdomains, from fundamentals to the internals senior engineers know. Pick one and go deep.
Build real applications with LLMs, agents and tools.
Languages, frameworks and more, taught the same way.
§ 02
Every lesson gives you three ways into the same idea, because understanding sticks when you see it, read it and use it.
01 · Watch
A short animated explainer, narrated, with Vora as your guide: diagrams move, data flows, code runs.
02 · Read
What are LLM evals?
LLM evals are systematic, repeatable tests that judge an LLM, or a system built on one such as an agent, against clear criteria. They're how you know an AI app works, instead of hoping it does.
A written deep dive at your own pace, with code that has been run before it was published.
03 · Practice
A teammate tries a new prompt on the same five questions they always use and says it's better. What's the main problem?
A short quiz that explains every answer, right or wrong.

LLM evals are systematic, repeatable tests that judge an LLM app against clear criteria. Learn why spot checks fail, how evals differ from classic tests, and the workflow to run them.
