Alibaba Releases HappyOyster 1.0 World Model: Real-Time Interactive AI Worlds with Physical Controls and Narrative Branching
English summary
Alibaba released HappyOyster 1.0, a world model that learns state transition dynamics from natural videos to generate interactive digital worlds from text or image prompts, ensuring long-range consistency. It features World Exploration mode with physical controls like attack, jump, and vehicle driving, and Real-time Director mode offering pause, backtrack, and branching narrative. The model targets gaming, virtual companionship, interactive short dramas, and tourism. Alibaba is collaborating with Nanjing University to create the first benchmark for world model evaluation. The product is available for registration on its official website, with full API access planned for the near future.
