Overview
HappyOyster 1.0 is a **world model** released by Alibaba Cloud on 2026-06-18, featuring '**generate a real-time interactive digital world with one sentence**'. It is not a simple video generation model, but a true **interactive, explorable, and instantly adjustable AI digital world generator**—users can **give real-time commands to adjust the scene** during generation, allowing AI to respond like a director to your ideas.
Two modes: **Real-time Director** (users say a sentence, AI adjusts the scene: 'Make that dragon fly over', 'Darken the sky', 'The crowd cheers') + **World Exploration** (generate a complete digital world for users to explore in first/third person). The base is Alibaba Cloud's **native multimodal architecture**, **joint audio-video generation**—sounds/music/dialogue in the scene are generated synchronously, not post-stitched.
This is a new contender in the world model space alongside Google Genie 3, Tencent HunyuanWorld, Meta SAM-3D, etc. HappyOyster differs from HappyHorse (video generation), Wan2.7 (image generation), Qwen-image (image understanding)—it is the 'fourth piece' of Alibaba Cloud's AI matrix.
