Origin & history
Interactive simulation is an older computing idea, but interactive world simulation became a distinct generative-AI label in the mid-2020s. The 2025 GameNGen paper described interactive world simulation with a neural model, and later projects extended the idea to controllable environments for robotics, autonomous vehicles, and other physical-AI systems.
