PICTURE THIS: A SENTENCE BECOMES TOKENS

The model does not read letters like humans. It reads these pieces, then predicts the next one.

Simple meaning

Randomness in token sampling.

1

WHY — Tokens instead of words?

LLMs use tokens (not full words) because it helps them:

LLM questions separate people

who only read docs from people who shipped.

Keep it short, concrete,

and tied to GenAI / LLM work.

Stable token IDs

Each piece maps to a number the network can learn.

Fits the model

Fixed pieces are what transformers expect as input.

2

STEPS — What happens with tokens?

Before the model can read a sentence, it goes through these steps:

  1. 1
    Tokenization

    Randomness in token sampling.

  2. 2
    Token IDs

    Higher is more creative

  3. 3
    Embeddings

    lower is more deterministic.

  4. 4
    Context mix

    Support bots usually stay low.

  5. 5
    Next token

    The model scores what should come next.

  6. 6
    Decode

    IDs turn back into readable text.

EXAMPLE — See it in action

Let's see how a real sentence is tokenized (tokens may vary by model):

Input text
“Higher is more creative”
Tokenized output
Higherismorecreative
Token IDs (example)
29874083374716

Note: Actual tokens and IDs depend on the tokenizer (e.g., GPT, Llama, etc.).

Key takeaway

Randomness in token sampling. Higher is more creative
