ALPS: Visual State Encoders for World Models

The paper introduces ALPS, a pretrained visual state encoder that integrates physical-state information, native language alignment, and pixel reconstruction into a single representation. Trained from scratch on still images and text, ALPS uses language, reconstruction, and spatial correspondence objectives, followed by cross-view self‑distillation. In evaluations across fifteen encoders, ALPS achieves the lowest aggregate LIBERO state‑probe error among ViT‑B models, while also delivering strong language alignment, accurate pixel reconstruction, and high policy success in downstream world‑model tasks.

MAViE: A Multi-scale Adaptive Vision Encoder for Fine-grained Visual Perception and Efficient Multimodal Reasoning

Vision-language models commonly project all tokens produced by a pretrained vision encoder into a large language model. However, final-layer features can discard text, local attributes, and spatial relationships, while high-resolution inputs substantially increase context length and inference latency.

WorldCast: Exploring Intelligent Visual Generation in World State Prediction

WorldCast is a benchmark that tests multimodal generative models on multi-step world state prediction, requiring them to forecast successive future states from multimodal observations and diverse references. The study evaluates 12 models across 320 manually designed cases in eight categories, revealing that advanced models like GPT-Image-2.5 achieve high scores while open-source models lag behind, especially on complex context and reasoning tasks. The results underscore the importance of integrating dynamic planning, reasoning, and unified multimodal capabilities for realistic world simulation.

WorldAgen: Unified State-Action Prediction with Test-Time World Model Training

WorldAgen is a unified framework that jointly learns world modeling and action prediction using a shared Transformer backbone with two specialized heads. It introduces a Mixed Unidirectional Attention Mask to separate the world model and agent model, and enables Test-Time Training (TTT) by sampling exploratory actions and updating the world model with real state transitions. Experiments on CALVIN and LIBERO show that WorldAgen matches or surpasses state‑of‑the‑art methods, especially when TTT is applied to a few samples.
