Models and datasets
Models and datasets: a model is patterns learned from data. Change the data and you change the behaviour, sometimes drastically.

AI Systems Foundations
Under every AI product sit three things: a model, data, and a set of trade-offs somebody chose.

The big idea
Students build an accurate mental model of how AI systems are assembled — what a model is, what data does, why outputs are probabilistic, and which limits are fundamental rather than temporary.
Why it matters
Applied work needs accurate foundations. Without them, students either over-trust systems or dismiss them entirely.
Unpacked
What you will actually learn
Three core ideas, each taught with worked examples and then practised until it feels obvious.
Probability intuition
Probability intuition explains why the same prompt gives different answers — the model samples from likely options rather than looking up one stored answer.
Limits and trade-offs
Limits and trade-offs are real: speed against quality, cost against capability, creativity against reliability. Every product picks a point.
Did you know?
The “temperature” setting controls how adventurously a model samples. Low temperature gives consistent answers; high gives creative and less reliable ones.
Common mix-up
“Bigger models are always better.” Bigger costs more and runs slower. Many production systems deliberately use smaller, faster models.
Session by session
Your 8-session journey
Sessions 1–8 of the 72-session year, at two one-hour sessions per week.
- 1
Warm-up and big picture
Where this module fits, what you will build, and a hands-on starter that gets everyone curious about models and datasets.
- 2
Models and datasets
Guided teaching on models and datasets, worked through together with the teacher.
- 3
Models and datasets — practice lab
Independent practice, small challenges and one deliberate mistake to diagnose.
- 4
Probability intuition
Guided teaching on probability intuition, building directly on the previous two sessions.
- 5
Probability intuition — practice lab
Applied tasks that combine models and datasets and probability intuition in one piece of work.
- 6
Limits and trade-offs
Limits and trade-offs introduced and practised, completing the toolkit needed for the project.
- 7
Project build
Guided build session for the module project: AI system concept map.
- 8
Test, present and reflect
Finish, test against the checklist, present the work and explain the decisions behind it.
Project lab
AI system concept map
Every module ends with something the student built themselves and can demonstrate. This is the piece that goes into their portfolio and gets explained out loud at the end of session 8.
Try this at home
Ask an identical question five times in fresh conversations and compare the answers. The variation is the probability made visible.
It is finished when
- It works from start to finish without breaking
- You can explain every part of it in your own words
- You tested it and improved at least one thing afterwards
- Someone else used or understood it without your help
By the end of this module
Students finishing Module 1 can:
- Explain and use models and datasets without prompting
- Explain and use probability intuition without prompting
- Explain and use limits and trade-offs without prompting
- Build and finish ai system concept map
- Test your own work and correct what you find
- Talk an adult through what you made and why
Word bank
The vocabulary introduced here, in plain language:
- model
- A system of learned patterns used to produce output.
- dataset
- The collection of data a model learned from.
- probabilistic
- Producing outputs based on likelihood, not certainty.
