Some AIs are huge brains; others are tiny enough to fit in a watch.

The big idea
Just like there are big dogs and tiny dogs, there are big AIs and tiny AIs. Big ones are smarter but slower and need huge computers. Tiny ones are quick but not as clever.
Some examples
A giant AI might know answers about almost anything.
A tiny phone-AI might just help you type faster.
Bigger isn't always better — tiny AIs are faster.
Some smart watches have an AI smaller than a postcard's worth of code.
Try it!
Notice when your phone shows a typing suggestion — that's a tiny AI! Compare it to a chat-AI's answer.
Practice this safely
Try this with a low-stakes example and a trusted adult nearby. The goal is to notice how AI talks about model size, not to let it make the decision for you.
Ask AI to explain model size in plain language, then underline anything that sounds uncertain or too broad.
Give it one detail from "Big AIs and Tiny AIs: Not All Are the Same Size" and ask for two possible next steps plus one reason each step might be wrong.
Check parameters against a trusted source, teacher, adult, expert, or original document before you use it.
