MULTIPLAYER REAL-TIME INTERACTIVE VIDEO WORLD MODEL
Enter the same world.
See it from every perspective.
Parallax enables multiple players to enter the same AI-generated world from independent viewpoints—exploring, interacting, and shaping a shared reality in real time.
THE PLATFORM
Generative video can create compelling images, but a living world must be entered, remembered, and changed.
Parallax separates world state from visual rendering. The world updates first, then each player receives a view shaped by their position, actions, and perspective. Every player sees something different while sharing the same underlying reality.
PLAYER ACTS → WORLD UPDATES → OTHERS RESPOND → THE WORLD EVOLVES
Discover how Parallax worksCORE CAPABILITIES
From a single idea to a shared interactive world, Parallax combines personalized map creation, real-time visual transformation, and state-first simulation.
Build the world you want to play.
Describe the experience you want, and Parallax turns your idea into a playable map with its own layout, landmarks, routes, and atmosphere—ready for multiple players to enter together.
PROMPT → SCENE GRAPH → PLAYABLE MAP
Change the look, preserve the world.
Transform materials, lighting, color, and artistic direction in real time while preserving the map structure, player positions, and shared interactions underneath.
SAME WORLD → NEW VISUAL STYLE
One world state. Every player in sync.
Every player acts on the same shared world state. Objects, actions, and environmental changes remain consistent across independent viewpoints as the world continues to evolve.
ONE SHARED STATE → MULTIPLE PLAYER VIEWS

Do Independently Controlled Views Describe One Shared World?
MultiWorldBench evaluates whether independently controlled player views remain grounded in one shared and persistent world—with consistent state updates, separate control, and memory across time.
Explore the benchmarkBenchmark for multi world models.
Evaluation code, benchmark definitions and world controllers are released together with the MultiWorldBench paper.
Why interactive worlds need a shared source of truth.
When every player acts on the same world state, multiple generated views become parts of one evolving reality—not separate video streams.
A persistent world must remember not only what happened, but where it happened. Spatial memory retrieves past observations according to the player’s current position and viewpoint.
TEAM
Parallax is an AI technology startup founded by a core team from Tsinghua. We are working to move AI from generating a clip of video to continuously generating a world that people can enter, experience, and change—exploring what real-time response, multiplayer interaction, and shared worlds can become.
We hope to make experiences created by AI richer and interaction more natural, to create new connections between people and AI and between people, and to turn imagination into an experience you can take part in.
We are building the foundation for persistent, shared, and playable generative worlds.
