Google DeepMind says Genie 4 can generate audio alongside an interactive world, including ambient sounds, music and dialogue. The company says the model can also respond to natural-language prompts in real time, changing details such as the weather or adding a person or object while keeping the scene coherent.

The model builds on the Gemini family: Google says Gemini Omni anchors simulations in real-world appearance and behaviour, while other Gemini models help maintain continuity. Users can steer scenes with text prompts and keyboard controls, according to Google.

Genie 4 is now rolling out as a research preview to trusted testers. Google says access will start with Google AI Ultra subscribers through Project Genie, alongside early-access partners using the Gemini API and Google AI Studio, before a wider release to consumers and developers.

Update What changed

OODALoop reports that Google DeepMind’s Genie 4 can generate interactive 3D environments at 720p and 24 frames per second. Those are specific performance figures absent from the earlier announcement and update; they come from OODALoop’s account, not a benchmark or technical document included here.

The report says users can create environments from text and image prompts, and describes the generated worlds as explorable and physics-consistent. It also says the model learns spatial dynamics and object permanence from video data, without requiring explicit game-engine coding.

These details offer a more concrete picture of the world model’s claimed capabilities, but the source provides no benchmark methodology or independent performance assessment. The figures are worth treating as reported specifications, not settled proof of how Genie 4 performs in practice.

Update What changed

A Google research experiment used Genie 4 to simulate a robot task broken into steps by a Gemini model, offering a possible way to test scenarios before trying them in the physical world. TechCrunch reports that the work used a Gemini 4 Argon model; it is an experiment, not evidence that Genie 4 is ready to train or validate real-world robots.

Google DeepMind engineer Tejas Kulkarni described a future in which Gemini could write code and text while Genie simulates the result at different levels of detail. That points to a potential role for interactive world models beyond making scenes to explore: they could help researchers rapidly prototype environments for robotics.

There are still rough edges. The report says details and objects can drift as simulations run longer, and the team has not yet solved audio accuracy or reliably legible in-world text.
