Google's Genie 2 "world model" reveal leaves more questions than answers
Briefly

When Google revealed the first version of Genie earlier this year, it also released a detailed research paper outlining the specific steps taken behind the scenes to train the model and how that model generated interactive videos.
Reading between the lines, it sounds like the full version of Genie 2 operates at something well below the real-time interactions implied by those flashy GIFs.
Real-time, interactive AI video generation isn't exactly a pipe dream. Earlier this year, AI model maker Decart and hardware maker Etched published the Oasis model, showing off a human-controllable, AI-generated video clone of Minecraft that runs at a full 20 frames per second.
However, that 500 million parameter model was trained on millions of hours of footage of a single, relatively simple game, and focused exclusively on the limited set of actions and environmental designs inherent to that game.
