Chapter 2: Generative AI Class 8

🧠 Chapter Overview

Generative AI is one of the most fascinating fields of Artificial Intelligence.
It not only analyzes existing data but also creates new content — such as text, images, music, and videos — just like humans!


2.1 Introduction to Generative AI

💡 Definition:

Generative Artificial Intelligence (Generative AI) is a branch of AI that can create new and original content such as text, images, videos, sounds, or code by learning patterns from existing data.

It doesn’t just recognize or classify — it generates something new.


🧩 Examples:

Tool / PlatformWhat It Generates
ChatGPTText, essays, code, ideas
DALL·E / MidjourneyImages and art
Synthesia / DeepFakeVideos
Jukebox / Suno AIMusic and audio
Copilot / CodeWhispererComputer code

📖 Simple Explanation:

If traditional AI answers your questions,
Generative AI writes new answers, stories, or even poems — it creates.

2.1.2 How Generative AI Creates New Content

Generative AI works by learning patterns, relationships, and structures from massive amounts of data and then using this knowledge to generate new, similar data.


⚙️ Steps in Generative AI Process:

StepDescription
1. Data TrainingThe AI is trained on large datasets (text, images, etc.)
2. Pattern LearningIt learns relationships, grammar, and context.
3. GenerationWhen given a prompt, it predicts what should come next.
4. RefinementThe model improves outputs using feedback and examples.

🧬 Common Generative AI Techniques:

  • Neural Networks – The brain of AI systems that mimic human neurons.
  • Transformers – Advanced architecture used in ChatGPT, BERT, Gemini.
  • Diffusion Models – Used in image generators like DALL·E and Midjourney.

💬 Example:

When you tell ChatGPT —

“Write a poem about the sun,”
it analyzes language patterns from millions of texts and creates a new poem that never existed before.
