Research on World Models Is Not Merely Injecting World Knowledge into Specific Tasks

2026-02-02

AI Summary

Current research on world models predominantly focuses on task-specific settings, lacking a unified framework for holistic world understanding. This work proposes a normative design framework for world models that, for the first time, cohesively integrates perceptual modeling, symbolic reasoning, spatial representation, and agent interaction mechanisms. By transcending the fragmented, task-oriented paradigms of conventional approaches, the framework offers structured principles for developing systematic, general-purpose, and robust world understanding systems. It thereby advances the field from an aggregation of isolated functionalities toward a unified cognitive architecture capable of comprehensive environmental comprehension and reasoning.

Abstract

World models have emerged as a critical frontier in AI research, aiming to enhance large models by infusing them with physical dynamics and world knowledge. The core objective is to enable agents to understand, predict, and interact with complex environments. However, current research landscape remains fragmented, with approaches predominantly focused on injecting world knowledge into isolated tasks, such as visual prediction, 3D estimation, or symbol grounding, rather than establishing a unified definition or framework. While these task-specific integrations yield performance gains, they often lack the systematic coherence required for holistic world understanding. In this paper, we analyze the limitations of such fragmented approaches and propose a unified design specification for world models. We suggest that a robust world model should not be a loose collection of capabilities but a normative framework that integrally incorporates interaction, perception, symbolic reasoning, and spatial representation. This work aims to provide a structured perspective to guide future research toward more general, robust, and principled models of the world.
