0.7.2 Generative AI

Overview

Generative AI refers to AI systems designed to produce new content in response to input.

Depending on the system, the output can include:

  • text;
  • images;
  • audio;
  • video;
  • code;
  • other generated media.

A text-based generative AI system might receive:

Activity diagram showing prompt, then model processes context, then model generates response content.
Prompt.
  • New
  • Changed
  • Removed

The technical implementation can be far more complex than this simplified flow.

For FIT, the important idea is that the response is generated, not retrieved as guaranteed truth.

Generative AI Can Transform Existing Information

Generation does not always mean creating something from nothing.

A generative AI system can also transform supplied content.

Examples include:

  • summarize these notes;
  • rewrite this paragraph more clearly;
  • turn these ideas into an email draft;
  • explain this code at an introductory level;
  • create a list of possible questions from this passage.

The user's input becomes context for the generated result.

Generative AI Can Help With Exploration

A learner might use generative AI to:

  • brainstorm possible approaches;
  • ask for another explanation;
  • generate examples;
  • draft wording;
  • organize ideas.

These uses can be helpful because the system can quickly produce candidate content.

Candidate content still needs evaluation.

Generative AI Is Not Automatically an Authoritative Source

A polished response can sound confident and complete.

That presentation does not prove that every claim is correct.

The system is generating an answer.

It may produce:

  • accurate information;
  • incomplete information;
  • unsupported information;
  • incorrect details.

The quality can vary across tasks and prompts.

Different Systems Have Different Capabilities

One generative AI system may work only with text.

Another may also accept:

  • images;
  • files;
  • audio;
  • other inputs.

Some systems may have access to external tools or current information.

Others may not.

Do not assume that one AI tool's capabilities apply to every other AI tool.

The Prompt Shapes the Task

Compare:

with:

The second prompt provides:

  • an audience;
  • a topic;
  • a desired distinction;
  • a length.

That additional information helps define the requested output.

The next Learning Activity looks more closely at prompts, inputs, and outputs.

Generated Does Not Mean Random

Generative AI is not simply choosing arbitrary words or pixels.

The output reflects patterns represented in the model and the context of the request.

At the same time, generation is not a guarantee of factual correctness.

Those two ideas belong together:

The output is pattern-based and purposeful.

The output still needs human evaluation.
