Today, we are announcing Genie 4, our new world model, which unlocks unprecedented realism and improves real-time interactive simulation. Genie 4 is natively multimodal, enabling audio-like music, ambient noises, and interactive dialogue to be simultaneously generated with the world.

The Genie 4 model incorporates and builds on capabilities from the Gemini family: Gemini Omni anchors the simulations in real-world appearance and behavior, while other Gemini models provide the complex reasoning needed to help maintain a simulation’s coherence and continuity.

With this foundation, you can set an event in motion, and Genie 4 simulates what happens next: how the world responds, how it sounds, and how the people in it move, react, and speak.

Understanding and simulating the world is a crucial aspect of building AGI. Genie 4 advances our ability to create safe, infinitely variable simulations that can help with everything from developing training environments for robots and agents to unlocking the creation of new interactive experiences.

We have started rolling Genie 4 out as a research preview for trusted testers — gathering feedback before we release it to consumers and developers, starting with Google AI Ultra subscribers in Project Genie and early access partners of the Gemini API and Google AI Studio. Join the waitlist for Genie 4 in Project Genie here.

The following are recordings of real-time interactions from Genie 4, where users use standard keyboard controls for navigation and camera control, and text prompts to steer the scene as it evolves.

Shaping world simulation in real-time

Pushing the frontier in realism for physics and human action

Genie 4 introduces a new standard of realism to real-time interactive simulation. Built on an advanced physical understanding of the world, Genie 4 simulates real-world physics scenarios, such as aerodynamics, collisions, and more.
