Simple meaning

LLM-as-a-judge uses another model to score an answer against a rubric.

1

WHY — Tokens instead of words?

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

Evals 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.

STEPS — What happens with tokens?

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

  1. 1
    LLM-as-a-judge uses another model

    to score an answer against a rubric.

  2. 2
    It scales better than

    full human review for open-ended text.

  3. 3
    You still need spot

    checks because the judge can be biased or inconsistent.

  4. 4
    Context mix

    Attention looks at nearby tokens together.

  5. 5
    Next token

    The model scores what should come next.

  6. 6
    Decode

    IDs turn back into readable text.
