World Model Interpretability: From Decoding Representations to Understanding Latent Worlds

arXiv 2026 26.4 method

TLDR

Perspective proposing a four-stage research agenda to interpret JEPA latent world models by understanding latent structure, causal verification, and intervention.

Reasoning

The paper offers a timely conceptual framework connecting latent world models and interpretability, but as a Perspective it lacks empirical validation and focuses on a research agenda rather than demonstrated results. Its strength is reframing interpretability from decoding representations to understanding latent dynamics; its weakness is the absence of concrete experiments or real-world evaluations.
