DeepMind's Genie 4 finally gives its world model a soundtrack
Google DeepMind shipped Genie 4, the first version of its world model that generates audio natively: ambient noise, music, dialogue that reacts to what you do inside the scene. Under the hood, Gemini Omni handles visual grounding while Gemini 3.8 Flash runs it as the guiding agent, watching the simulation and replanning as it unfolds.
