AstraBrain

AstraBrain is Galaxy Universal's self-developed embodied intelligence foundation model, branded in Chinese as "银河星脑" (Galaxy Brain). Per Source Code Capital's March 2026 coverage, it claims to be the world's first end-to-end full-body, full-hand embodied large model integrating "brain-cerebellum-neural control" into a single architecture — a generational leap over the conventional approach of splitting task planning, motion control, and dexterous manipulation into separate modules . The model's core breakthrough is high-dimensional generalization: rather than executing pre-programmed trajectories for specific tasks, AstraBrain uses reinforcement learning to let robots acquire general "how to interact with the physical world" capabilities through billions of virtual-world trials, enabling adaptive, human-like "see-think-act" behavior . Its capabilities were demonstrated on the Spring Festival Gala stage, where it performed tasks like walnut-rolling with fingertip force control and real-time deformation adaptation while folding clothes . By August 2026, Galaxy Universal had extended the AstraBrain ecosystem with AstraBrain-WBC 0.5, a general cerebellar foundation model with 80.4 million parameters trained on roughly 20,000 hours of human motion data, alongside a WAM-TTT test-time training framework that adapts to new environments from minimal human video without extensive robot trajectory data .
