Study proves latent-prediction world models are exponentially more data-efficient than token predictors

Latent models predict internal abstractions rather than raw tokens.

Shameless plug but this nice work supports our ICLR paper—ICL Activation Alignment—pretty much spot on.

- Activations (internals) provide a much stronger learning signal than just tokens.

- Brings sample efficiency and avoids spurious correlation learning.

LLMs learn by predicting tokens. World models (JEPA, data2vec) learn by predicting their own abstractions. Which needs more data? For data with hidden hierarchy, we prove the gap is exponential. https://arxiv.org/pdf/2605.27734
