Researchers have introduced InterCMDM, a novel block-causal latent diffusion framework designed for autoregressive human interaction generation. This model utilizes a Dual-Stream Causal Diffusion Transformer to maintain separate causal streams for each individual while modeling inter-person dependencies through unified dual-stream attention with multi-task attention masks. These masks allow for the control of diverse coordination behaviors, such as simultaneous actions, reactive responses, and leader-follower dynamics, by simply selecting the desired mask at inference time. The framework's block-wise diffusion objective enables stable latent rollouts over extended sequences without requiring repeated decode-encode cycles, achieving state-of-the-art performance on benchmarks like InterHuman and Inter-X by improving text-motion alignment, realism, and long-horizon continuity.
