Understanding GPT & AI: A Complete Guide

The AI Revolution

Artificial intelligence has moved from science fiction to daily life. ChatGPT passed the bar exam. AI generates art, writes code, and threatens to transform every industry.

But what actually is AI? How does GPT work? What can it do — and what can't it? This collection cuts through the hype to explain what's really happening.

What You'll Learn

What Is AI?

Artificial intelligence is machines doing tasks that typically require human intelligence. But there are different types:
• Narrow AI: Excels at specific tasks (chess, image recognition)
• General AI: Human-level intelligence across domains (doesn't exist yet)
• Superintelligence: Beyond human intelligence (theoretical)

Machine Learning Basics

Most modern AI is machine learning: systems that improve from experience. Instead of programming rules, we train models on data.

Neural Networks

Inspired by brains, neural networks are layers of connected nodes. Deep learning uses many layers. This enables breakthrough capabilities in vision, language, and more.

GPT and Large Language Models

GPT (Generative Pre-trained Transformer) predicts the next word in a sequence. Trained on internet-scale data, it develops remarkable capabilities — and limitations.

The Future

Where is AI heading? Multimodal models. AI agents. Safety concerns. Job displacement. The debate over consciousness.
