Google introduces Genie 4, the next generation of its world model

Google has released Genie 4, a new version of its world model focused on realism, multimodality, improved physics and real-time interactivity.
Google has introduced Genie 4, the next generation of its world model. The previous version was released more than a year ago, in August 2025.
The new release focuses on realism, multimodality, improved physics and interactivity. The model generates worlds in real time.
Key focus areas:
- realism;
- multimodality;
- improved physics;
- interactivity.
It remains to be seen when someone will plug a fly’s brain into this simulation.
Why it matters
AnalysisGenie 4 could push real-time world simulation toward practical uses for agent training, game design and robotics, where physics fidelity and interactivity matter.
