Google DeepMind lets you generate playable worlds in real time
Google just rolled out Project Genie, an experimental research prototype powered by its Genie 3 world model, Nano Banana Pro, and Gemini. Instead of static 3D environments, it simulates physics and renders paths ahead in real time as you walk, fly, or drive through user-prompted worlds. For now, generations are capped at 60 seconds and limited to Google AI Ultra subscribers in the U.S.
