AstraBrain

Galbot's embodied model family, connecting a “brain” that plans with a “cerebellum” that handles real-time whole-body control.

AstraBrain is Galbot's umbrella name for its embodied model family; the Beijing-based humanoid company describes it as an end-to-end “brain–cerebellum–neural control” architecture. AstraBrain-WAM is the “brain,” a world-action model (predicting future images and generating actions at the same time); Galbot's website lists it at 3 to 13 billion parameters, outputting high-level commands at 5–10Hz and handling task understanding and long-horizon planning, and the company says it can draw on simulated and real-robot data, and human and robot data, with or without action labels, all in one framework. AstraBrain-WBC is the “cerebellum,” an 80-million-to-300-million-parameter Transformer that does real-time whole-body and hand control at 100–250Hz, trained on large-scale human motion data. AstraBrain-Dex is a world model aimed at dexterous hands. WAM 0.5, WBC 0.5, and a test-time training framework called WAM-TTT, all disclosed in 2026, belong to this same family. Most of these figures and claims come from the company itself.

ExampleIn a 2026 demo, Galbot showed a humanoid robot autonomously playing tennis — seeing the incoming ball, predicting its trajectory, moving into position to hit it, and keeping its balance — which the company describes as whole-body control achieved jointly by the brain and cerebellum models.
