World-Language-Action Model for Unified World Modeling, Language Reasoning, and Action Synthesis

Researchers introduce World-Language-Action (WLA) models, a new class of embodied foundation models that combine world modeling, language reasoning, and action synthesis for robotic control. The WLA-0 prototype demonstrates state-of-the-art performance across multiple benchmarks, achieving 92.94% success on RoboTwin2.0 and 56.5% on RMBench while running at 40ms inference on consumer GPU hardware.

Can Image Models Imagine Time? ImageTime: A Novel Benchmark for Probing Visual World Modeling Through Spatiotemporal Consistency

Researchers introduce ImageTime, a diagnostic benchmark that evaluates whether image generation models can coherently imagine sequences of visual states over time. The benchmark requires models to generate four ordered keyframes representing an action's progression, revealing significant gaps in how current AI systems understand temporal consistency and causal relationships in visual narratives.

Policy and World Modeling Co-Training for Language Agents

Researchers propose PaW, a co-training framework that enhances language model agents by simultaneously optimizing reinforcement learning policies and world models using data from standard RL rollouts. The approach eliminates the need for separate simulators or training stages while demonstrating consistent improvements across multiple benchmarks.

OOWM: Structuring Embodied Reasoning and Planning via Object-Oriented Programmatic World Modeling

Researchers introduce Object-Oriented World Modeling (OOWM), a framework that structures LLM reasoning for robotic planning by replacing linear text with explicit symbolic representations using UML diagrams and object hierarchies. The approach combines supervised fine-tuning with group relative policy optimization to achieve superior planning performance on embodied tasks, demonstrating that formal software engineering principles can enhance AI reasoning capabilities.

How Much LLM Does a Self-Revising Agent Actually Need?

Researchers introduce a declarative runtime protocol that externalizes agent state to measure how much of an LLM-based agent's competence actually derives from the language model versus explicit structural components. Testing on Collaborative Battleship, they find that explicit world-model planning drives most performance gains, while sparse LLM-based revision at 4.3% of turns yields minimal and sometimes negative returns.
