◇ THE WIRE · BREADTH FIRST

The AI Engineer Atlas

The horizontal bar of your T. Nine domains span the whole field — tap one to see the wire, then use the Bloom ladder below to drive deep.

EXT = extended production domains — learn the six core ones first.

PRIORITY

RAG / Retrieval

THE WIRE

Fetch relevant docs, paste into prompt, answer from them.

WHY

How models answer about YOUR data they were never trained on.

GO DEEP

Chunking → vector DB → hybrid search → reranking → eval.

↓ THE STEM · DEPTH LADDER

Bloom's 6 levels. You don't truly "know" a topic until you reach the top and create with it. Tap a rung.

EDGES OF THE MAP

Beyond this map: multimodal (vision/audio) and voice agents exist out there and aren't covered yet — know they're there.

T-shaped path: skim all nine domains shallow first → then drive RAG & Evals to the top rung.
