AI Concepts
Single-page visual guides on core concepts, system architectures, tooling, and infrastructure - structured for rapid scannability and deep technical clarity.
Basics: Start Here
Five foundational questions every AI newcomer asks. If you're new to LLMs, start here - each page takes 5 minutes and explains one core concept in plain English.
Question 1
What is an LLM?
What large language models actually are, how they work at a high level, and what you should know before using one.
Question 2
What is a Token?
The basic unit of AI economics - how tokens work, why they determine cost, and why different languages cost different amounts.
Question 3
What is Prompting?
How to communicate with AI - system prompts vs user prompts, common mistakes, and techniques that get better results.
Question 4
What is an AI Agent?
The difference between a chatbot and an agent - tools, autonomy, and the loop that lets agents keep working until the job is done.
Question 5
What is a Context Window?
Every LLM has a memory limit - what fits in the window, what happens when it's full, and how to manage it effectively.
