Happy Oyster
Open-World 3D Model
A real-time world engine that generates physically consistent 3D environments from text or images. Stream, interact, and direct — all in real time.
About Happy Oyster
Happy Oyster is an open-world model product from Alibaba's ATH division. Named after Shakespeare's "The world is your oyster," it represents the second release in the "Happy Universe" series following HappyHorse.
Streaming Generation
Break the linear "prompt → render → output" workflow. Continuously receive user commands and respond in real time.
Physics Simulation
Deep simulation of gravity, collision, and lighting changes. Maintains high stability during perspective transitions.
Audio-Visual Sync
Native joint audio-video generation architecture. Environmental sound effects automatically match visual content.
Active World Simulation
Transforms content production from passive generation to active world evolution simulation — closer to a real-time rendering engine.
Core Modes
Wander Mode
First-person perspective exploration. Generate a complete 3D space from a single sentence or image with physical consistency.
Director Mode
Switch cameras, direct character actions, and change storylines at any point during video generation.
Use Cases
Game Development
Rapidly generate playable prototypes, lowering the barrier to game content production.
Film Production
Real-time storyboard generation with modification at any node, dramatically improving creative efficiency.
Education & Tourism
Walk into famous paintings or historical civilizations from a first-person perspective.
Robotics Training
Provide simulation training environments for robots and autonomous driving systems.
