Most people treat prompting like talking to a person.
That's the wrong mental model.
LLMs don't "understand" you — they predict the next
token based on probability. Once you internalize this,
everything about prompting changes.
The Core Mechanic: Next Token Prediction
Every word you get back is a statistical calculation.
The model asks: "Given everything before this, what
word comes next?"
That's it. No reasoning. No understanding. Pure
probability.
Why This Matters for Your Prompts
Temperature controls how "creative" that
probability is:
- Low (0.1–0.3) → consistent, deterministic
- High (0.7–1.5) → creative, but hallucinates more
Attention is where most people lose — the model
distributes focus unevenly. Put your critical info at
the start or end of your prompt, not buried in the
middle.
The Takeaway
Prompting isn't magic. It's knowledge design —
structuring information so the model's probability
engine points where you want it to go.
