Google introduces Genie 4 as a research-preview model for interactive worlds

Google introduced Genie 4, describing it as its most realistic and interactive world model. According to the description, it can steer dynamic environments in real time—including events, camera angles, and actions—generate audio matched to a world, simulate photorealistic scenes and real-world physics, and create more coherent multi-step events through Gemini reasoning. Google has begun rolling it out as a research preview; one participant said they did not yet have access and suggested an application to an early-access program might be required. The hosts discussed possible uses in video games and creator tools, such as virtual backdrops and real-time set extensions. These were forecasts and examples of potential applications, not confirmation that commercial tools with these capabilities are already available.
