Architecture Workshop
Coming soonDesign an AI system, explain your choices and adapt the design when a requirement changes.
Learn to explain the decisions behind AI applications
Clear foundations in how AI applications are built, and realistic interview problems to practise on.

RAG: How it works and when to use it, a free article in the RAG collection, open in the Orthic reader.
AI Engineering
The concepts AI engineering
interviews ask about
Nine concepts to start, in a set order. Each one is a short set of articles with diagrams and a quiz.
Browse AI EngineeringModels & APIs
Understand messages, model responses, streaming and structured output.
Evals
Check how an AI system behaves against clear criteria.
Prompt Engineering
Shape the instructions and context you give a model.
Tool Use
Define safe tools and handle calls, results, errors and limits.
RAG
How an AI application finds passages in your documents and uses them to answer a question.
Model Capabilities
Use images, documents, citations, caching and code execution deliberately.
MCP
Use the open standard that lets any AI application connect to the same tools and data.
Workflows
Compose model calls with routing, chaining, parallel work and explicit state.
Agents
Build bounded agent loops and introduce multiple agents only when justified.

Start with
the right question
Before you design anything
Can an employee read every document in their own company?
Practice · Coming soon
Practise designing and
debugging AI systems
A document assistant that many companies share, where no company may see another’s files. Design it, then work out why it leaked.
Incident Room
Coming soonInvestigate an AI failure, find its cause and decide what must be checked before it restarts.
Feedback
Feedback you can act on, never a number
Each answer gets feedback on what you got right and what to add. There are no scores or grades, because a number can’t tell you which risk you missed.
Part of the way there.
- What you handled well
- You tied every document and chunk to one company, so ownership is clear before search runs.
- What to add or change
- Some documents are limited to a group, so being in the same company isn’t enough to read them. Add the groups that can read each chunk.
