💡 AI Concept of the Day: The Sora Moment: When Video Models Became Physics Engines
For years, computer graphics and artificial intelligence existed in parallel universes. To get a realistic physics simulation, you needed a game engine with explicitly programmed rules for gravity, collision, and light. To get a creative image, you used a generative model.
The “Sora Moment” in early 2024 collapsed these two worlds. When OpenAI released their technical report, they notably did not title it “A Better Video Generator.” They titled it: Video Generation Models as World Simulators.
This signaled a profound shift in the research agenda. We are no longer just generating pixels for entertainment; we are creating Data-Driven Physics Engines.
