In the last few months, I’ve spoken with a lot of industry professionals like software engineers, consultants, senior managers, scrum masters, and even IT support staff about how they use generative AI (GenAI) and what they understand about Artificial Intelligence. Many of them believe that using “AI” means interacting with applications like ChatGPT and Claude or relying on their integrated applications like Microsoft Copilot. While these are excellent tools for your day-to-day activities, they don’t necessarily teach you how to build a GenAI application from the ground up. Understanding these technicalities is crucial to brainstorming ideas and creating use cases to solve and automate your work. 

There are thousands of tutorials on large language models (LLMs), RAG (retrieval-augmented generation), and embeddings; many still leave novice AI enthusiasts confused about the “why” behind each step.
