The big idea
AI, ML, LLMs — the words get thrown around like they mean the same thing. Here's a simple mental model that finally made it click for me. This article breaks that down step by step, assuming zero prior background and explaining every term the first time it shows up.
Why it matters
I'm a self-taught Efficiency Engineer, not a researcher — so everything here is framed around what actually helped me get unstuck and make progress. If it didn't move the needle for me as a beginner, it didn't make the cut.
What you'll take away
You'll leave with a mental model you can reuse, the confidence to keep experimenting on your own, and a clear next step. Curiosity over credentials — always.
