your_turn

The machine picks the next token. Now you try.

Three prompts. Guess the next token before the model reveals its odds. Score 3/3 and you are the autocomplete.

the_deal

Walk out with six things you built.

Every session ends with working code in your hands, not notes about someone else's code.

S1

Your first AI script

Your own API key, your own code, calling a frontier model — before you leave the first session.

S2

An eval harness

A tester that measures whether AI answers are right — like an engineer, not a fan.

S3

A vision app

Upload a photo, interrogate it. AI that reads documents, receipts and handwriting.

S4

Chat with your notes

An AI that answers from your study material — RAG, the pattern behind most real AI products.

S5

A tool-using assistant

AI that calls tools your code controls — and the judgment to know when not to build an agent.

S6

A hardened capstone

You attack each other's apps, patch the holes, and demo a real product to the room.

no_hidden_jargon

The whole syllabus, said plainly.

If a concept matters in real AI engineering, it's named here up front: taught from scratch, then used in a lab the same afternoon. Hover any chip: a course that can't define its vocabulary in one plain line doesn't own it.

the_format

One weekend. A rhythm, not a lecture.

day_1 · sessions 1–3

Understand the machine

Next-token prediction, prompting and evals, vision and images. Overnight: bring your own documents for Day 2.

day_2 · sessions 4–6

Arm it, then ship it

RAG on your own notes, tool use and agents, security and production — ending in capstone demos.

every session, the same rhythm

Half the course is laptops-open lab time. The talks exist to make the labs land — not the other way around.

the_sessions

Six sessions, one throughline.

PredictMeasureSeeKnowActShip

Each session hands its verb to the next. By Sunday evening the sentence is yours.

01
predict

Next-token prediction, tokens, embeddings, attention, training vs inference — the whole engine, every idea a live demo, including a neural network you watch think.

→ you build: your first AI API call
02
measure

Prompt engineering that works, why polished prompts still lie beautifully, and how engineers measure quality with numbers instead of vibes.

→ you build: an evaluation harness

AI Beyond Text

17 slides · ~2h

Vision that reads documents, diffusion that paints from static, voices cloned in seconds — and why it's all the same loop.

→ you build: a vision app
04
know

Embeddings, semantic search, chunking, and RAG end to end — the single most useful pattern in applied AI.

→ you build: chat with your own notes
05
act

Making AI Do Things

23 slides · ~2h

Tool use, the agent loop, MCP, why workflows beat agents most days — plus a frontier model running on a bare laptop.

→ you build: a tool-using assistant
06
ship

Live prompt-injection attacks, defense in depth, what production actually costs — then you demo your capstone.

→ you build: a hardened, shipped app

Colab notebooks for all six labs ship in the labs/ folder of the course repo.

the_arguments

Every session stops once to pick a fight.

One deliberately debatable claim per session, defended on stage. The deck goes lights-off for it. Disagreement is part of the syllabus; the strongest counter-argument gets named on the closing slide.

session_1

If autocomplete can pass your exam, your exam was never testing understanding.

session_2

Hallucination is not a bug. It is the model doing exactly what it was trained to do.

session_3

Your mother's voice is no longer proof of your mother.

session_4

Your final-year project is one grounded prompt away from being a startup.

session_5

Most production "AI agents" are a while-loop in a trench coat.

session_6

There is no secure AI agent. Only one whose blast radius you've made small enough to survive.

the_method

Why it's built this way.

This course exists to prove a point about teaching AI, and it wants to be copied.

Vote before the reveal

Every big idea arrives as a game: the room predicts, shouts, commits — then the answer lands. A brain that guessed wrong remembers forever.

Build before the jargon

Raw API calls before frameworks, your own retrieval loop before "vector database" is ever said. You earn every abstraction before you're allowed to use it.

Honest failure is curriculum

Demos that can fail live stay in the deck. Hallucinations get measured, not apologized for. The fine print is taught with the magic.

Measure, don't vibe

"It worked when I tried it" is not evidence. From Session 2 onward, every claim about AI quality must survive an eval.

If you only listen, you forget. Here, everyone ships — in every session, on any laptop, for free.
your_instructor

Built by someone who ships this for a living.

Karthikeyan NG heads engineering at Vision, a fintech and crypto platform in Dubai — where RAG pipelines, eval harnesses and agent guardrails are production reality, not slideware. Along the way: two startups founded, two published books on machine learning, eighteen hackathon wins, and stages at TEDx, Google, IIT Kharagpur and Seoul.

The course began where you might be sitting now — an engineering classroom (CSE '09, Madurai). He built the course he wishes he'd had, and credits most of what it teaches to the hundreds of things he shipped that failed.

the_course_kit

Everything is in the box. Take it, teach it.

Six interactive decks, six labs with notebooks and handouts, six cheatsheets, a complete learning guide, per-slide timing, and instructor prep packs. Swap Madurai for your city and run it anywhere.

questions

The ones everyone asks.

Does it really cost nothing?

Yes. The labs run on Google AI Studio's free tier (no credit card) and free Google Colab. The whole course fits inside the daily free limits — the lab handouts even budget the API calls per exercise.

What laptop do I need?

Anything that opens a browser. All heavy computation happens in Google's cloud; your machine just needs a keyboard and Wi-Fi. A ₹15,000 laptop is exactly as capable here as a MacBook Pro.

Do I need math or ML background?

One line of school math appears in the whole course: y = wx + b. If you can write a for-loop in any language, you have every prerequisite.

Can I self-study without an instructor?

Yes. The decks are self-contained and interactive, every lab has a step-by-step handout with checkpoints, and pressing S in any deck shows the full speaker narration. The Learning Guide covers every concept in prose.

Is my data private on free tiers?

Assume free-tier conversations may train future models. The course drills one rule from Session 1: never paste anything you couldn't survive seeing on the front page of the newspaper.

Can I teach or translate this?

Please do — that's the point. Teach This Yourself covers running it at any scale, and the Madurai references are designed to be swapped for your own city's.
