HappyOyster 1.0

Alibaba's HappyOyster 1.0 is an interactive world model that renders explorable video from a written prompt and a single opening frame. Model Studio lists three API models for it, released on 17 September 2026, although the product was unveiled in April 2026 with early access.

Main features

• Adventure: a user explores a world using direction, camera and action commands.
• Directing: builds a scene from written instructions or a script, with pause, rewind and resume.
• Acting: creates a character in a chosen persona, portrait 9:16 by default.
• Integration: a server-side REST interface sets up worlds and short-lived credentials, while client SDKs for Android, iOS and the web receive the output over a real-time audio and video channel.

Teams building interactive drama, film previsualisation, or role-play and video-call-style companions, according to Alibaba's description of its modes.

Key facts

• Regions: Adventure is the only mode listed for the China (Beijing) region.
• Status: Acting is an invitational preview.
• Hosting: the models are proprietary and hosted only, and each world is bound to the model that created it.
• Parameters: Alibaba publishes no parameter counts.
• Independent coverage: none was found for the September API release, and the 17 September date comes from Model Studio's listing.
