XAI, a company founded by Elon Musk and started with “TruthGPT,” is shifting its focus from language understanding to a lower level goal: a world model. This information was first disclosed by the Financial Times on October 11, 2025. According to the report, xAI is developing “a world model that can be used in video games and robotics,” and has recruited two researchers from NVIDIA, Zeeshan Patel and Ethan He to participate. The term “world model” has been around in academia for many years. It refers to a model that can internally reconstruct and predict changes in the state of the environment, so that AI can not only “understand data,” but also mentally simulate the evolution of the world. This concept has received renewed attention in organizations such as DeepMind and Nvidia in recent years, and is considered a path to embodied intelligence.
