Once you internalize this,<br> everything about prompting changes.</p> <h2> The Core Mechanic: Next Token Prediction </h2> <p>Every word you get back is a statistical calculation.<br><br> The model asks: "Given everything before this, what<br> word comes next?"</p> <p>That's it. No reasoning. No understanding. Pure<br> probability.</p> <h2> Why This Matters for Your Prompts </h2> <p><strong>Temperature</strong> controls how "creative" that<br><br> probability is:</p> <ul> <li>Low (0.1–0.3) → consistent, deterministic </li> <li>High (0.7–1.5) → creative, but hallucinates more</li> </ul> <p><strong>Attention</strong> is where most people lose — the model<br><br> distributes focus unevenly. Put your critical info at<br> the start or end of your prompt, not buried in the<br><br> middle. </p> <h2> The Takeaway </h2> <p>Prompting isn't magic. It's knowledge design —<br><br> structuring information so the model's probability<br> engine points where you want it to go. </p> ai promptengineering llm beginners
