AIsphere launches PixVerse R2, a real-time world model with session memory

AIsphere, maker of the PixVerse video platform, launched PixVerse R2, a general-purpose real-time world model that generates continuous, interactive audiovisual worlds instead of fixed clips. Released on September 23, it follows R1 from January and opens demo spaces for games, interactive films and digital humans at world.pixverse.video. R2 splits work between the causal autoregressive Omni Causal AR backbone and a Real-Time Acceleration layer.

• R2 launched September 23, following R1 introduced in January
• Users control characters with WASD, change camera and type prompts live
• Error Bank cut a long-horizon brightness-drift metric by 35.8% in internal tests
• Single-pass quality still trails leading offline video models
