Google’s Genie 4 world model adds audio, more realistic worlds, and real-time steering

Google DeepMind released Genie 4 in research preview, a world model that generates photorealistic, interactive worlds with real-time audio and lets users type prompts mid-simulation to change scenes, weather, camera angles, or add objects. It maintains a consistent scene for up to two minutes, double Genie 3's limit, and integrates with Gemini, which plans steps while Genie creates visuals; a Gemini Robotics experiment had a Gemini 4 Argon model break tasks into steps that Genie 4 simulated in real time. Genie 4 is available now to trusted testers and 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 Google AI Studio.
