Monday: Sorters and Makers

Rocket stares at the empty space on the mission poster. "We have no comet picture for the middle."

"Sky Sorter has seen comet snapshots," he says. "Can it just draw us a new one?"

Raven shakes her head. "Sky Sorter only picks a label. Star, planet, comet or streak. It never makes anything new."

Nova hums and projects a soft grid of light onto the poster. "Sorting and making are two different jobs," she says.

"One chooses from a short list. The other builds something that did not exist before."

"So what kind of system would you need to make a new picture?"

Two different jobs

Sky Sorter takes a snapshot and picks one label from a short list. That is a sorting job.

Generative AI does a different job. It makes new content that did not exist before.

NIST describes generative AI as models that imitate the structure of the data they learned from.

They make "synthetic" content, such as images, videos, audio and text.

  • Sorting AI: takes an input and picks a label, such as "comet".
  • Generative AI: takes an input and makes new content, such as a paragraph or a picture.
  • Synthetic content: text, images, audio or video made by a computer system.
SORT OR MAKE?
  • Read the question.
  • Tap your answer.
A system reads a snapshot and answers "planet". Is that sorting or making?
A system writes a brand-new paragraph about a comet. Is that sorting or making?
Which of these is synthetic content?
StatementTrue or false?
Generative AI can make text, images, audio and video.?
Sky Sorter is a generative AI because it uses snapshots.?
Generative AI imitates patterns in the data it learned from.?
Synthetic content always comes from a person typing it.?
WHY THIS EXERCISESky Sorter sorts; generative AI makes new content that imitates its training data.

Talking in everyday language

Some AI systems can talk with people in natural language, the everyday words we speak and write.

The AI4K12 Five Big Ideas says advances in deep neural networks, such as large language models, are making this possible.

Nova talks in our story because she is a story character. Real AI is a tool that people build.

Content made by a computer system instead of directly by a person is called ____ content. Type one word.
WHY THIS EXERCISESynthetic content is made by a computer system, like the output of generative AI.
Try it
List five things you used or saw today, such as a message, a song or a poster.
Next to each, write who or what made it: a person, a recording, or you are not sure.

Strong start. Tomorrow you peek at the trick behind text that a machine writes: predicting the next word.
