The AI Skills Guide Part 3. From Intermediate to Advanced in 2026.

Welcome to Learn AI from AI. I am Brian.

This is Part 3. The big one. If Part 1 gave you the language, and Part 2 gave you the habits, this episode gives you the architecture. Today we cross the line from using AI to designing systems with AI. We will cover multi‑agent systems, connecting AI to your own tools, prompt chaining at scale, and the things that separate hobby projects from real, reliable systems. Cost. Privacy. And trust.

This is the level where AI stops being a helper and becomes infrastructure. Let us go.
