The X Brain team is building an intelligent system capable of continuous self-iteration, and the potential for imagination is quite large.

The entire architecture is divided into three layers, tightly integrated:

**The first layer is the world model**—equivalent to the central nervous system of the system. Its job is not just to process text, but to ingest large amounts of real and virtual data, then output predictions about physical laws and strategic recommendations. It sounds a bit abstract, but this is indeed the necessary path for general AI.

**The second layer is embodied intelligence**—bringing AI from the screen into the real world. No longer just software, but entities with perception capabilities and the ability to perform actions. They complete tasks in real environments while continuously feeding back underlying physical data, and this feedback loop is very critical.

**The third layer is spatial intelligence**—a highly realistic mixed reality environment where virtual training and the real world can interact and map in real time. This accelerates the evolution of intelligence by multiple orders of magnitude.

These three layers drive each other, forming a closed loop. And XB is the fuel that keeps this cycle running. Understanding X Brain's ecosystem layout from this perspective makes it clearer what they are working on.
