PixVerse R2 scales its real-time world model into persistent, playable video worlds
- PixVerse released R2, the successor to R1 (January 2026), a real-time world model that keeps a generated world running and holding its state while a user navigates it live.
- R2 splits generation into two stages on one foundation: Omni Causal AR scales a single model across more data, input types, tasks, and longer sessions, and a real-time acceleration layer compresses it to run live, so speed is not traded for capability.
- In PixVerse's internal evaluations, R2 cut visual drift across a long session by 35.8%.
- Inputs persist inside a session in R2: an earlier action stays true later in the same session, and the model accepts text, references, audio, and action controls within one running world.
- Creator Xiaolongbao built Zero Mark, an interactive film-game on R2 where the story branches from player input (a dragon or a leaf for a creature) and each outcome is generated live.
