## Summary

Google DeepMind has unveiled Genie 4, an updated world model that Google says improves on Genie 3 in almost every way. World models generate interactive virtual environments frame by frame from a text description, without pre-rendered assets. Google says the model adds audio and more realistic people and physics, and that updated Gemini models help it simulate what users request.
