Basic Principles of Generative AI

What is Generative AI?​

Generative AI refers to a family of artificial intelligence models capable of creating content. Unlike traditional AI that classifies or predicts, generative AI can write, draw, translate, chat, compose music, and more often in a way that feels creative or interactive.

Common types of generative AI:

  • Language Models: Generate text, answer questions, simulate conversation (e.g., GPT-4, Claude, Gemini).
  • Image Models: Create pictures, diagrams, or illustrations from descriptions (e.g., DALL·E, Gemini Vision).
  • Audio Models: Produce speech from text (text-to-speech) or transcribe spoken language (speech-to-text).
  • Multi-modal Models: Combine text, images, and/or audio in a single system.

Key Concepts Every Creator Should Know​

1. Training Data & Generalization​

  • Generative AI learns from very large datasets compiled from language, images, or audio found online and in archives.
  • This means it predicts or generates new content by “pattern matching”. It does not think, reason, or have lived experiences.

2. Prompting (Input) Matters​

  • The AI responds to your instructions called prompts.
  • The clearer and more specific your prompt, the more likely you’ll get useful, relevant output.
  • Prompts can be questions, instructions, examples, or even scenarios.

3. Probabilistic Output​

  • Generative AI outputs are not deterministic:
    The same prompt may sometimes yield different results.
  • Most models let you control “creativity” or randomness (temperature) higher values = more varied output; lower = more predictable.

4. Strengths and Limits​

  • Strengths: Scale, speed, adaptability, creativity, and language/comprehension.
  • Limits:
    • Can make mistakes (sometimes called “hallucinations”).
    • May reflect bias or offensive content from its training data.
    • Is blind to real-time events and personal context unless programmed otherwise.

5. Human-in-the-Loop​

  • Effective use of generative AI always involves a human partner:
    • Set the purpose
    • Guide the AI with tasks and constraints
    • Check, correct, and improve outputs

What Generative AI Cannot Do​

  • Think or feel independently
  • Guarantee factual accuracy
  • Know confidential or personal information about users (unless given in the prompt/context)
  • Always follow nuanced ethical/cultural norms automatically

Generative AI in Education: Opportunities and Cautions​

Opportunities:

  • Custom learning materials (quizzes, worksheets) in seconds
  • Personalized conversations or feedback
  • Simulation of real-world scenarios (role-plays, storytelling, branching cases)

Cautions:

  • Always review AI outputs (don’t blindly trust AI-generated results!)
  • Avoid sharing sensitive or confidential information in prompts
  • Be mindful of copyright and fairness (don’t pass off AI work as original if originality is needed)
