What even is an LLM?
A next-token guesser. Not a librarian with facts on a shelf.
1 · Chop into tokens
6 tokensone chunk each. Until a rare word splits
Course voice
Okay, but what is a token?
Finally understand what AI is actually doing. By doing it yourself. Drag tokens, run real prompts, break the model on purpose.
No coding required. Playground 1 is free.

Three labs that sell the course.
See the labs →Who is this for?
No maths, no coding, no prior knowledge needed. If you can use a web browser, you can do this course.
What you will know after
Written for someone who has never written a line of code.
Explain exactly why AI invents facts. And how to catch it before it embarrasses you
Write prompts that consistently get useful results instead of vague non-answers
Know when to trust AI output and when to verify every word
Understand context windows, temperature, and tokens. Without needing to code
Use AI to draft, critique, and improve your own writing without losing your voice
How each playground works
Every playground follows the same structure. You never hit an exercise without first understanding what it’s for.
Theory
A short written explanation in plain language. What this playground is for, before you try anything
Examples
See the concept in action: drag tokens, watch rankings shift, compare outputs side by side
Exercise
Try it yourself in a live sandbox. With a real AI model, not a simulation
Conclusion
One plain-language takeaway you can use in your job tomorrow

Beat 02
Short chunks of text with numbers attached. The model ranks what should come next.
2 · Rank the next token

Course voice
So it isn’t searching. It’s ranking.
Beat 03
Pick one guess. Append it. Repeat. Fluency shows up. Truth is optional.
3 · Keep going → a sentence

the steamer's light was already too close to the rocks for anyone on shore to pretend they hadn't seen it.Course voice
That’s why you verify. And why we make you poke it.
Playgrounds
Start with what an LLM is, see a made-up detail, then watch the loop, chop tokens, rank guesses, and feel luck change on a live model.
Four dials, not magic words
Fluent and wrong at the same time
Paste the truth into the prompt
One prompt is rarely the finish line
Noise, then better guesses
Waves from guesses, not a tape
A loop with tools, not a smarter chat
Fluency is not proof
About ten minutes. No account required. Judge the course by playing it.
