SimLens for Early Exit in Large Language Models: Eliciting Accurate Latent Predictions with One More Token

ArXi:2507.17618v2 Announce Type: replace Intermediate-layer predictions in large language models (LLMs) are informative but hard to decode accurately, especially at early layers. Existing lens-style methods typically rely on direct linear readout, which is simple but often drifts away from the model's eventual prediction. We proposeSimLens, a simple
