Before we begin: The goal of this article is to help you understand how LLMs work in simple language. I've intentionally avoided deep technical details.
If you've used ChatGPT, Claude, Gemini, or another AI chatbot, you've probably wondered:
How does it understand my question and write an answer?
The answer is simpler than it sounds.
A Large Language Model (LLM) doesn't write the entire response at once. It first understands your input, then generates the answer one small piece at a time.
