What is World Model?
TL;DR
An AI model that can simulate physical laws and causal relationships of the real world. Seen as the next frontier beyond LLMs.
World Model: Definition & Explanation
A World Model is an AI model capable of internally simulating real-world physics, causal relationships, and temporal changes, and making predictions based on that understanding. It is attracting attention in 2026 as the next major technology beyond text-based LLMs. World models can understand and predict how objects move, what happens when force is applied, and how things change over time. Key initiatives include Meta's V-JEPA, Google's Genie, and the foundational technology behind OpenAI's Sora. Applications are anticipated in autonomous driving, robotics, game AI, and video generation, and world models are considered essential for realizing Physical AI. NVIDIA is leveraging world models through its Omniverse platform for digital twin construction. World models represent AI's evolution from understanding 'language' to understanding 'the physical world.'
