Alibaba Cloud Launches HappyOyster 1.0, a World Model for Real-Time Interactive Digital World Generation
Alibaba Cloud has released HappyOyster 1.0, an open world model that generates complete, interactive digital worlds from a single sentence. The model learns physical state transitions, maintains long-range consistency, and supports multimodal input with real-time audiovisual generation. Unlike traditional one-shot rendering, it continuously responds to user instructions during generation. Two modes are offered: real-time directing, where users can pause and rewrite storylines, and world adventure, where users control characters with keyboard input to explore, fight, and traverse diverse environments. The product opened internal testing on April 16, 2025, and provides daily free experience points until July 17, 2025.
