Generative AI Explained: A Comprehensive Guide Free Learning Platform

In today's fast-paced digital world, artificial intelligence (AI) is transforming how we live and work. Among its many branches, generative AI stands out as a revolutionary concept that enables machines to create human-like content. This blog post is a detailed recap of a powerful lecture delivered by Sir Zafar Iqbal, an AI expert known for his exceptional ability to teach AI concepts for free.

This post is perfect for beginners, students, and aspiring developers who want to understand the fundamentals of generative AI and how it's shaping modern technology. 

Here is Lecture 1 of AI for All.

The Evolution of AI: From 1950 to Today

The journey of AI began in the 1950s, when scientists aimed to create intelligent systems that could replicate human thinking. By the 1990s, Machine Learning (ML) gained traction, teaching computers to learn from data and make decisions. In the 2010s, Deep Learning emerged, using neural networks to make more accurate predictions and decisions.

These foundational developments paved the way for Generative AI, an innovation that mimics human creativity.

What is Generative AI?

Generative AI refers to systems that produce new content based on a prompt. This content may include:

• Text (e.g., ChatGPT)
• Images (e.g., MidJourney)
• Audio (e.g., AI voices)
• Video (e.g., Google's VideoFX)

It understands a user's input and generates original, human-like responses, making it one of the most powerful tools in AI today.

Generative AI Tools in Use

Sir Zafar highlighted some leading tools that fall under Generative AI:

Text Generation:

• ChatGPT (OpenAI)
• Gemini (Google)
• Microsoft Copilot

Image Generation:

• Google Imagine
• MidJourney

Video Generation:

• Google Vivo
• Runway ML

Code Generation:

• Claude (Anthropic)
• Codex (OpenAI)
• GitHub Copilot
• Replit

Tokenization in Language Models

One of the core building blocks of Generative AI is tokenization. It breaks down text into smaller parts (tokens), often words or subwords. Each token is assigned a unique number, making it easier for the model to understand and predict text. This helps LLMs handle large inputs and generate accurate, context-based responses.

Parameters vs Hyperparameters

AI models are shaped by two critical variables:

• Model Parameters: Learned during training. These adjust the model to improve predictions.
• Hyperparameters: Set before training begins. They guide how the model learns.

Think of these as the knobs on a stereo, adjusting volume, bass, and treble to fine-tune your output.

GPT and Large Language Models (LLMs)

GPT (Generative Pre-trained Transformer) is the foundation behind many popular AI tools. GPT models are trained on massive datasets to generate human-like responses. Examples include:

• GPT-4 (OpenAI)
• Claude Opus (Anthropic)

These LLMs can summarize, translate, generate text, and even code all by understanding natural language.

Multimodal Systems: The Future of AI

Multimodal systems process and respond to multiple types of input: text, image, audio, and video. Earlier AI models were limited to text. Today’s advanced systems combine everything into one interface, offering a more complete user experience.

Popular multimodal models include:

• GPT-4
• Gemini
• Claude 3 (Anthropic)

Open Source vs Proprietary Models

Sir Zafar also discussed the difference between open-source and proprietary models:

• Proprietary: Not openly accessible. Examples include GPT-4 and Claude 3, used through APIs and subscriptions.
• Open-Source: Freely available models like LLaMA 3, DeepSeek R1, and Gemini, which developers can retrain or modify to build custom AI solutions.
