Achieving a high degree of controllability and real-time interactivity in Genie 3 required significant technical breakthroughs. The system processes user inputs multiple times per second while maintaining 24 FPS generation, which requires sophisticated computational management. During the auto-regressive generation of each frame, the model has to take into account the previously generated trajectory that grows with time, meaning every new frame must consider the entire history of user interactions and environmental changes up to that point.
The real-time interaction system operates on two levels: immediate navigational responses and dynamic world modifications. For navigation, users can move through environments and the system responds instantly, generating new viewpoints and maintaining spatial consistency as they explore. The more complex interaction layer involves promptable world events, where users can issue text commands to modify the environment during exploration. To achieve real-time interactivity, this computation must happen multiple times per second in response to new user inputs as they arrive. This means the system must rapidly process both movement commands and environmental modification requests without breaking the immersive 24 FPS experience.
The technical challenge of real-time interaction lies in balancing responsiveness with consistency. Unlike traditional video generation where the entire sequence is planned, Genie 3 must make decisions about future frames based on unpredictable user inputs while maintaining coherence with past frames. The system accomplishes this through efficient memory management and computational optimization, allowing it to reference relevant information from previous frames (up to one minute back) while generating new content in real-time. This approach enables users to have meaningful agency over their experience, whether they’re simply exploring environments or actively reshaping them through text prompts.
