The Sequence Knowledge #821: 4D and World Models and the Amazing DeepMind D4RT
One of the most exciting areas in world models.
Today we will Discuss:
World models in 4D.
Exploring the amazing D4RT from DeepMind.
💡 AI Concept of the Day:
The evolution of “world models” has reached a pivotal inflection point: the shift from predicting pixels in 2D video to reconstructing the physical geometry of a dynamic world in 4D. As highlighted in Part 4 of our series for The Sequence, this frontier is defined by Spatial Intelligence—the ability of an AI to not only see a scene but to perceive its volume, its occluded parts, and its temporal trajectory with mathematical precision.
