How an LLM Actually Works

Click each stage to explore how a Large Language Model processes your prompt and generates a response. It is not magic — it is pattern matching at an extraordinary scale.

1

Your Prompt

You type a message. The model receives raw text — it has no idea who you are, your clearance level, or your role in Defence.

2

Tokenisation

Your text is split into tokens — chunks of words, subwords, or characters. Each token maps to a number the model can process.

3

Embedding & Attention

Each token becomes a high-dimensional vector. The attention mechanism figures out which words relate to which, resolving ambiguity in context.

4

Next-Token Prediction

The model calculates the probability of every possible next token. It does not “know” the answer — it predicts what text is statistically most likely to follow.

5

Token-by-Token Output

One token is selected, appended, and the process repeats. Each new token considers everything before it. This is why responses stream in piece by piece.

Key insight: LLMs do not understand anything. They are sophisticated pattern-matching machines. This is why they can sound confident while being completely wrong — they predict plausible text, not verified facts. For Defence personnel, this means every AI output must be treated as a draft, never as a source of truth.
