When that prediction is wrong or surprising, developers often want a more specific question answered: <strong>how did the model&rsquo;s candidate tokens change as the input moved through the network?</strong></p> <p>The <strong>logit lens</strong> is a simple interpretability technique for exploring that question. Instead of waiting for the final layer, it takes an intermediate representation and passes it through the model&rsquo;s final decoding machinery to obtain vocabulary logits. Repeating this across layers gives a rough view of how token predictions evolve with depth.</p>
