Raw Input

Real: User Input

This is where everything begins — your raw text, exactly as you typed it. The model has not touched it yet. Before any processing can happen, the text needs to travel through a series of transformations. Think of this stage like dropping a letter into a mailbox: the words are human-readable, but the postal system needs to convert them into something it can route and deliver.

Common misconception: The model does not "read" your text the way a human does. It cannot understand letters or words directly. The raw input is just a string of characters that will be broken apart, converted to numbers, and transformed beyond recognition before the model ever acts on it.
