Generative AI and Large Language Models for Beginners

Generative artificial intelligence is transforming how we work, write, and solve problems, yet understanding how these systems actually function can feel overwhelming. This text-based course demystifies the core concepts of generative AI and large language models (LLMs) without requiring a technical background. You will transition from a curious observer to a knowledgeable practitioner who understands how these models are trained, how they generate text, and how to write effective prompts. What you'll learn: - Understand the fundamental differences between traditional machine learning and generative AI. - Explain how large language models are trained and how they predict text. - Apply basic prompt engineering techniques to get more accurate and useful outputs. - Identify the core concepts of retrieval-augmented generation (RAG) and vector databases. - Evaluate the ethical challenges, bias risks, and limitations of modern AI models. The journey begins with essential terminology and the historical shift from analytical to generative systems. You will then progress through the mechanics of text generation, practical prompting strategies, and the real-world considerations of deploying AI responsibly through written explanations and conceptual exercises. This course is designed for absolute beginners, business professionals, and curious learners with no prior programming or computer science experience.
