Understanding the Complex: How Does an LLM Work?
If you already know what a neural network is, what training means, and how probability distributions work, you can skim this lesson. Everything introduced here will come up again in Lessons 4–6.
For everyone else: this lesson gives you four concepts — and only four. Not a computer science textbook. Not a full introduction to machine learning. Just what the next three lessons need.
