Excited to share Genie 4 today our most realistic and interactive world model:

- steer dynamic environments in real time, shaping events, camera angles, and actions

- generate native audio matched to the world, from realistic background sounds to characters who can converse in real time!

- simulate photorealistic scenes and real-world physics

- create more coherent multi-step events through reasoning from Gemini

We've started to roll out as a research preview to trusted testers. Coming soon to Google AI Ultra subscribers in Project Genie and early access partners via the Gemini API and AI Studio.

The demo above shows how all these capabilities come together in real time. Prompt “traffic light green,” and Gemini reasons through what happens next as the signal changes: the engine revs, and the motorcycle accelerates down the coast.

Full prompt here:

Environment: A sun-drenched coastal highway viewed right at the white stop line of a beachfront intersection, where an overhead traffic light hangs prominently in the immediate foreground glowing bright red. Running parallel to the road strictly along the right-hand side is a golden sandy beach and shoreline with rolling turquoise ocean waves under a clear blue sky.

Character: Shot from a first-person POV seated on a motorcycle positioned right up close to the traffic light, facing straight ahead over the handlebars, side mirrors, and dashboard. With the sea and shore visible on the right side of the frame, the rider rolls the last few feet up to the white crosswalk line and comes to an idling stop directly beneath the glowing red signal, gloved hands resting on the grips while waiting for the light to change.
