Duo: A Reciprocal World Model for Full-Duplex Interaction

Duo v1 is a full-duplex world model that continuously perceives audiovisual inputs while responding to users in real time. The Reciprocal World Model treats intelligence and physical reality as equally fundamental to what constitutes a world. Duo v1 uses autoregressive modeling for continuous interaction reasoning and constructs chunk-specific conditions and synchronize tokens across Intent and Realization on a unified timeline.
