Requirements

❗ No prior AI or machine learning experience is required. This course starts from the fundamentals and builds your understanding step by step.
❗ Basic computer skills and curiosity about Artificial Intelligence are enough to get started.
❗ A willingness to learn technical concepts through simple explanations and practical examples.
❗ Programming experience is helpful but not required, as the course focuses on understanding concepts before implementation.

Description

This course contains the use of artificial intelligence.
Have you ever wondered how ChatGPT and modern AI assistants actually work?
This course provides a complete beginner-friendly journey into the world of Large Language Models (LLMs) and Generative AI. You will learn the core concepts behind today's most powerful AI systems and understand how they transform human language into intelligent responses.
Starting from the fundamentals, you will explore how Large Language Models process text using tokens, tokenization, embeddings, neural networks, Transformers, and attention mechanisms. You will understand how AI models learn patterns, generate responses, and represent meaning mathematically.
Throughout the course, you will discover the complete lifecycle of modern LLMs
• How text becomes tokens and token IDs
• How embeddings allow AI systems to understand relationships and meaning
• How neural networks and Transformers power modern language models
• How attention mechanisms help models focus on important information
• How LLMs are trained, evaluated, and improved
• How context windows, prompting, and token efficiency affect AI applications
• How Retrieval-Augmented Generation (RAG) connects LLMs with external knowledge
• How modern AI applications are built using LLM technologies
This course focuses on understanding the technology behind AI applications, not just using AI tools. You will build the mental model needed to confidently explore AI engineering, RAG systems, AI agents, and LLM-powered applications.
By the end of this course, you will have a strong foundation in Large Language Models and understand the concepts used behind ChatGPT-style applications.
