Learn to build with AI

The bits nobody writes down, in the order you actually need them.

Free, hands-on courses for engineers who can already code but have not built with LLMs. Lessons are short and stick to the real mechanics — what the model is doing, why it does the odd thing it just did, and what to reach for instead. Each one ends with a quick recall quiz.

Build with LLMs

You can already code. This is the other half — what the model actually is, how to make it do what you asked, how to give it your data, how to let it act, and how to prove it works.

LLMs

What these models actually are, who sells them, what open weights really buy you, and how to pick one without guessing. The layer under everything else you build.

Prompt Engineering

Past the tricks. How instructions actually land, which techniques survive contact with real traffic, how to validate what comes back, and how to stop a prompt edit from quietly breaking last week's behaviour.

RAG

Your answer can never be better than what you retrieved. Embeddings, vector stores, chunking, hybrid search and reranking — the whole pipeline, and how to tell which part of it is letting you down.
