It only decides.</p> <p>Here is the real difference.</p> <p><a href="https://media2.dev.to/dynamic/image/width=800%2Cheight=%2Cfit=scale-down%2Cgravity=auto%2Cformat=auto/https%3A%2F%2Fdev-to-uploads.s3.us-east-2.amazonaws.com%2Fuploads%2Farticles%2F5pyy8v94cdwulwag49ju.png" class="article-body-image-wrapper"><img src="https://media2.dev.to/dynamic/image/width=800%2Cheight=%2Cfit=scale-down%2Cgravity=auto%2Cformat=auto/https%3A%2F%2Fdev-to-uploads.s3.us-east-2.amazonaws.com%2Fuploads%2Farticles%2F5pyy8v94cdwulwag49ju.png" alt="LLM vs Jev: an LLM generates tokens one at a time then parses the text; Jev scores every typed question in one forward pass and returns probabilities" width="800" height="450"></a></p> <p><strong>LLM:</strong> reads the prompt, writes the answer one token at a time, and leaves you to parse the text.</p> <p><strong>Jev:</strong> reads the state once, answers every question in a single parallel pass, and returns typed values with probabilities.

<li> <strong>LLM</strong> when you need generation: writing, reasoning, explanation</li> </ul> <p>Most real systems should use both.</p> <p><strong>Bottom line:</strong><br> Stop using a generation
