Happy Oyster is an open-ended world model that lets people create and interact with evolving scenes in real time. It understands text, voice, and images, then responds with synchronized audio and video as the world keeps changing. There are two main modes: Directing, where users act like live directors and change camera angles, characters, or story direction on the fly; and Wandering, where users explore infinitely extendable worlds in first person. It’s built for things like real-time film production, interactive drama, world creation, and immersive exploration.
