Next-Latent Prediction Transformers Learn Compact World Models

arXiv:2511.05963v2 Announce Type: replace Abstract: Transformers replace recurrence with a memory that grows with sequence length and self-attention that enables ad-hoc lookups over past tokens. Consequently, they lack an inherent incentive to compress history into compact latent states with consistent transition rules. This often leads to learning solutions that generalize poorly. We introduce Next-Latent Prediction (NextLat), which extends standard next-token training with self-supervised predictions in the latent space. Specifically, NextLat trains a transformer to learn latent representati

Why this matters
Why now

The paper addresses a known limitation of current transformer architectures regarding efficient knowledge representation, at a time when 'world models' are a major research frontier.

Why it’s important

Improving the efficiency and generalization of foundational AI models directly impacts the capabilities and accessibility of future AI systems, potentially leading to more robust and less resource-intensive AI.

What changes

This research suggests a pathway to more compact and generalizable AI models by incentivizing internal compression of 'world knowledge,' potentially reducing the need for extremely large models and training datasets for certain tasks.
