a(nother) talk about AI*/LLMs

they’re A Thing now

Hi, I’m Ben

PhDLecturerKids

The problem

everyone uses ChatGPT (classrooms, office work, group chats)

most folks don’t have a good mental model of how it works…

…and this is a problem

The gap

some feel this “don’t know how it works” anxiety more than others, e.g. classroom teachers

CS Unplugged has been teaching computing concepts without computers for 20+ years

  • algorithms & data structures
  • traditional ML/AI
  • LLMs?

What would “LLMs Unplugged” look like?

  • end-to-end generation (training → generation)
  • modular and low-friction
  • broad accessibility (no coding, minimal maths)

(spoiler) it’s live at llmsunplugged.org

Historical roots

Markov (1913) and Shannon (1948)

did this work by hand

counting letter sequences in Pushkin’s Eugene Onegin (Markov)

generating synthetic text through weighted sampling (Shannon)

The core insight

language models work by

  1. counting patterns in existing text
  2. exploiting these patterns to generate new text

modern LLMs: same approach, vastly greater scale

The core mechanic

Training: counting word pairs

Text: “See Spot run. See Spot jump.”

Preprocessed: see spot run . see spot jump .

seespotrun.jump
seeII
spotII
runI
.I
jumpI

the grid is the model

Demo time

Why this works

  • the randomness explains why LLMs give different responses to the same prompt
  • the weighting explains why output is usually coherent
  • this is how LLMs work, just smaller

Lesson structure

Fundamentals

two core lessons (do in order):

  1. Training—counting patterns into a grid
  2. Generation—weighted sampling with dice

available in grid and cutouts variants

about 30mins each (but flexible)

Reception

Notes from the field

over 500 participants over the past year

  • senior executives and public servants
  • undergraduates (all disciplines)
  • high school teachers
  • school-age students

LLMs are “just” probability and randomness at scale—not reasoning, not understanding, but sophisticated pattern matching

The shareback moment

the room comes alive during the generation lesson when groups share the output from their model

“fish fish fish red one fish two fish”

“I do not like green eggs and you may see me be I do not…”

Resources

What’s available

  • lessons with instructor notes
  • interactive widgets
  • videos (coming soon)
  • software tools for custom n-gram booklets

Next steps

  • continued development (esp. extensions)
  • teacher training
  • evaluation (inc. via partnerships)
  • strengthen curriculum links (e.g. ACARA)
  • translations
  • keen to hear your experiences

This Friday

Lifting the Veil—a hands-on AI workshop for educators with Brimbank Tech School at VU Sunshine Campus

Friday 13 February, 10am–3pm
