One Lens, Many Worlds : A Capability-Typed Interface for World-Model Interpretability
Researchers have developed WorldModelLens, an open-source interpretability tool designed to standardize how we analyze world models in AI. This new substrate uses a capability-typed adapter, requiring models to implement core methods like encoding and transition, while also supporting optional heads for tasks such as decoding or reward prediction. The goal is to allow interpretability methods to be written once and applied across diverse world model architectures, including latent state-space models, token-based models, and joint-embedding architectures, without needing custom implementations for each.
