What is a Large Language Model? What does a harness do? What do you need an SDK for? You'll get answers here. Step by step, with examples, no prior knowledge required.
"The LLM communicated with the harness via the API, and the agent called the tool through MCP." If all you understood there was word salad: that's exactly why this page exists. We take every word apart, one at a time, with calm words and pictures that stick in your head.
You can go through them in order, or jump straight to the topic you're interested in right now.
API, SDK, harness, agent, MCP, RAG, you'll know not just what it is, but also what it is not.
You'll recognize when an AI is inventing a plausible-sounding story, and when it really knows what it's talking about.
You'll understand why small changes to a prompt have huge effects, and how to use that on purpose.
You'll be able to assess which problems are a good fit for AI, and which are better left alone.
Every chapter starts with an everyday analogy. Every unfamiliar term is explained the first time it appears. Every chapter ends with a three-point summary. If a concept is hard, we slow down, not speed up.
