LeCuration: A Tiny World Model as a Data Curation Multi-Tool Researchers introduced LeCuration, a small world model built on the LeWorldModel (LeWM) latent encoder and predictor with an added diffusion transformer (DiT) decoder, to curate data for physical AI applications. In a qualitative proof-of-concept case study on CS:GO gameplay data, the model's embeddings served as an anomaly detection signal and a content-based clustering heuristic, and autoregressive game-state prediction allowed qualitative checks of action-state consistency. The authors report no quantitative curation metrics or downstream training results yet, identifying those as the key next step. arXiv:2610.09285v1 Announce Type: new Abstract: Many applications of physical AI run within finite or closed physical worlds with a limited set of physical laws governing object behavior. Examples include robots working in a warehouse and agents moving around in a video game. In order to better organize, filter, and curate data for physical AI applications, we propose a new approach centered on the unique settings and physical laws of individual datasets. We train LeCuration, a small world model intended to serve as a data curation tool for a separate, larger downstream model. To build this model, we choose LeWorldModel LeWM as our latent encoder and predictor, adding a diffusion transformer DiT decoder to add visuals to autoregressive gameplay rollout. We find that the embeddings of this model can be used as an anomaly detection signal and as a content-based clustering heuristic, and that auto-regressively predicting the game state with this model allows us to qualitatively check for action-state consistency. This paper presents a qualitative, proof-of-concept case study on CS:GO gameplay data; we do not yet report quantitative curation metrics or downstream training results, which we identify as the key next step.
