Musk is entering the gaming industry: recruiting two key players from NVIDIA, xAI aims to create a "world model"

Elon Musk's company xAI, which started with "TruthGPT," is shifting its focus from language understanding to a more fundamental goal: world models. This news was first reported by the Financial Times on October 11, 2025. The report noted that xAI is developing "world models that can be used in the fields of video games and robotics," and has recruited two researchers, Zeeshan Patel and Ethan He, from NVIDIA to participate in this effort. The term "world model" has existed in academia for many years. It refers to a model that can internally reconstruct and predict changes in environmental states, allowing AI not just to "understand data," but to simulate the evolution of the world in its mind. This concept has gained renewed attention in recent years at institutions such as DeepMind and NVIDIA, and is considered a pathway to embodied intelligence
