High-Frequency Interview Questions on World Models (2026 Version): From Predictive Modeling to Physical AI: 120 High-Frequency Interview Questions on World Models

High-Frequency Interview Questions on World Models is a structured interview preparation guide for one of the most important directions in modern AI: world models.This book covers 120 carefully designed questions across foundational concepts, model-based reinforcement learning, JEPA, V-JEPA 2.1, Genie, Cosmos, Physical AI, autonomous-driving world models, VLA models, robotics world models, spatial intelligence, and agentic world modeling.Unlike generic AI interview books, this guide treats world models as the core infrastructure connecting perception, prediction, planning, action, and counterfactual simulation. Each question is organized into three parts: a plain-language explanation, a mathematical derivation, and a concise summary. This structure helps readers not only memorize answers, but also understand the reasoning behind them.The book is especially useful for candidates preparing for AI, machine learning, robotics, autonomous driving, embodied AI, multimodal learning, and foundation model interviews. It is also valuable for researchers, engineers, and students who want to understand how world models are evolving from video prediction systems into the foundation of Physical AI and intelligent agents.Inside this book, readers will learn how to explain key concepts such as latent dynamics, belief states, predictive representations, action-conditioned futures, learned simulators, interactive world generation, counterfactual reasoning, and VLA-based world modeling.If you are preparing for advanced AI interviews or trying to understand the next major direction after large language models and multimodal models, this book provides a systematic, interview-oriented roadmap to world models.
