Start before LLMs. Understand where AI, ML and neural networks fit.
Layer
A layer is a stage of computation in a neural network that transforms one representation into another.
Think of it like
Think of Layer as one layer in a very large toolbox: you only need to understand what job that layer performs.
Real life
A phone spam filter, recommendation engine, fraud detector or voice assistant may use Layer somewhere inside.
SRE lens
Transformers stack many layers, so deeper models require more compute and memory.
