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.

Genie 4 delivers enhanced photorealism, fluid movement, and native audio. All accompanying sounds featured above are produced directly by Genie 4.

Genie 4 advances four key capabilities 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 With Genie 4, you can use natural language to modify a simulation in real-time — like changing the weather, moving the camera, or introducing a new person or object — and Gemini will contextually adapt your prompt to match the surrounding scene. Between your inputs, Gemini also monitors and steers the scene to keep the world progressing cohesively.

Prompt: Use the reference image as the exact first frame and visual basis for the scene. Preserve the same floating rectangular platform, weathered concrete edges, wild grasses, ferns, twisted small tree, warm glowing amber sphere, and the same middle-aged man in a loose brown suit playing a brass saxophone. A cinematic, highly naturalistic documentary scene, photographed on 16mm film with subtle grain, soft photographic detail, extremely low contrast, muted natural colors, lifted shadows, gentle highlights, and soft diffuse overcast light. Absolutely no HDR, no dramatic contrast, no glossy digital rendering, no artificial cinematic lighting. The platform floats in the middle of a vast, quiet lake surrounded by distant misty forests. Thin layers of fog drift above the water. The sky is pale blue-gray and overcast, with a soft, almost monochromatic atmosphere. The warm amber sphere provides a delicate contrasting glow, softly illuminating the surrounding vegetation and reflecting in the lake. Begin with a slightly closer view of the saxophone player than in the reference image, while keeping the platform, glowing sphere, tree, and surrounding lake visible. The man continues playing his saxophone naturally, with subtle breathing, finger movements, and gentle body swaying. The camera moves independently and can freely explore the entire environment, gliding smoothly over the water with gentle, controlled movement. The camera is not attached to the man or the platform. Maintain realistic spatial continuity and natural camera movement. Everything must remain photographic, physically believable, documentary-like, extremely low-contrast, and softly desaturated throughout the entire experience. One continuous shot. Natural lake ambience, distant wind, soft water movement, and realistic saxophone sound. No background music beyond the instruments physically present in the scene.

Environment prompt: A wide, sun-drenched hilltop meadow filled with tall green grass and scattered purple, white, and yellow wildflowers swaying in a warm breeze. Low green shrubs dot the right side of the field while distant blue-green rolling hills stretch along the left horizon beneath a bright, partly cloudy sky. Character: Winding in sweeping S-curves through the center of the grassy meadow from the immediate foreground far into the distance is a long, continuous stream of glossy bubblegum-pink satin fabric. The shimmering pink cloth billows, ripples, and lifts softly above the wildflowers like a flowing river of silk as the wind moves beneath its folds.

Environment prompt: A sweeping aerial view over the vast, frozen landscape of Antarctica, featuring endless snow-covered glaciers, jagged icy mountain peaks, and sculpted blue icebergs bathed in crisp polar sunlight under a clear, pale blue sky. Numerous hot air balloons dot the horizon at varying altitudes, with a large cream, red, and blue striped balloon floating prominently in the mid-distance above the ice sheet. Character prompt: Shot from a first-person POV standing inside the woven wicker basket of a flying hot air balloon, looking out over the leather-trimmed basket edge on the right side of the frame, where black padded support poles, metal rigging chains, and the dark base of the balloon canopy overhead frame the drifting polar vista.

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...
