Google DeepMind unveils Genie 4 world model with real-time audio

Google DeepMind has released Genie 4, its newest world model, as a research preview for trusted testers. It generates its most photorealistic, interactive worlds yet, lets users type prompts mid-simulation to change scenes or weather, and adds matching real-time audio including music, ambient sound and dialogue. The launch comes as rivals like Runway push their own world models.
