Google DeepMind released Genie 4, its newest "world model," as a research preview for trusted testers on Oct. 27. It generates interactive, real-time simulated worlds that users steer with the keyboard and change with text prompts mid-simulation, for example switching the weather or camera angle or adding people and objects. DeepMind calls it its first real-time world model to generate audio natively, including music, ambient sound and dialogue.

TechCrunch reports that Genie 4 keeps a scene consistent for up to two minutes, double Genie 3, with Gemini acting as a director that plans steps and checks frames. Google pitches uses in gaming, learning and robotics, and testers point to prototyping films. DeepMind says details and objects can drift over longer sessions, and that audio accuracy and legible in-world text remain open problems. Output carries SynthID watermarks. It will roll out in the coming weeks to Google AI Ultra subscribers in Project Genie and to early-access partners of the Gemini API and AI Studio.
