Motubrain: A World Action Model
Built on the proprietary UniDiffuser framework and a three-stream MoT architecture, Motubrain unifies perception, planning, and execution within a single model. It integrates world prediction and action generation into a unified framework, supporting tasks such as VLA, world modeling, video generation, inverse dynamics modeling, and video-to-action prediction. With strong cross-embodiment adaptation, cross-task generalization, and long-horizon execution capabilities, Motubrain enables robots to develop human-like physical intuition and reliably accomplish complex end-to-end tasks across real-world environments, including homes, industrial facilities, and commercial settings.
Real-World Task Demonstrations
Motubrain can execute long-horizon task sequences end-to-end, involving more than ten atomic actions while maintaining stable subtask transitions and temporal consistency. The physical action dynamics it models exhibit strong generalization and cross-embodiment transferability, enabling unified generalization across diverse robotic embodiments.

World Action Model Motubrain: A New Paradigm for Multi-Task Generalization and Scalable Evolution in Embodied Intelligence
Motubrain is built on the UniDiffuser unified modeling framework. Through Cross-Modal Prior Fusion, it integrates vision-language knowledge (VLM), video dynamics knowledge (Video Generation Models), and action skill knowledge (Action Experts) within a single model, enabling unified representation and generation across language, video, and actions.
Top-Ranked on Two Leading International Benchmarks
Motubrain ranked first on two leading international benchmarks, demonstrating strong performance in the unified modeling of perception, planning, and action.
