Applied AI courses

Long-form, structured reading for engineers moving into applied AI. They assume you can program and assume nothing about AI, and each lesson links into the question bank so you can practise what you just read.

The main path

Walked front to back. Start here if you are new to building with language models.

Applied AI Engineering

A structured path from writing normal software to building and shipping systems on top of language models. Assumes you can program and nothing about AI. Eight modules, from what the job actually is through to the interview that gets you it.

01What this job actually isfree
02How language models work, enough to build onfree
03Prompting as an engineering disciplinefree
04Retrievalfree
05Tools and your first agent5
06Evaluation5
07Production6
08The interview4

AFTER THIS YOU CAN

→Explain how a language model turns your text into an answer, and reason about what each step costs
→Write prompts that produce structured output a program can rely on
→Design and debug a retrieval system, and know when retrieval is the wrong answer

Agent Engineering

Agents are the most over-applied pattern in applied AI and the hardest to make reliable. This course covers the loop, tool design, memory, multi-agent coordination, and evaluation, with as much attention on when not to build one as on how.

01What an agent is, and when not to build onefree
02The single-agent loopfree
03Tools as an interfacefree
04Memory and context3
05More than one agent3
06Making it reliable4
07Evaluating agents5
08Agents in the interview2

AFTER THIS YOU CAN

→Place any system on the autonomy spectrum and justify where you put it
→Design tool schemas that a model can actually use correctly
→Budget an agent's context instead of letting it grow until something breaks

HOW THESE FIT WITH THE REST OF THE SITE

Courses teach the path: what to learn, in what order, and why. The concept curriculum is the reference for any single idea, and the question bank is where you practise under interview conditions. If you already know the material and just want to prepare, start with the essentials instead.
