Architecture — Zuba | The Full Stack, Engineered for Scale
> ARCHITECTURE

Five layers. One owner.

From silicon to substation, the full stack sits inside one ownership model — designed for what’s actually running frontier AI.

> THE STACK

to explore.

Each layer is engineered for a specific role in the AI compute stack. Zuba owns and leases the GPU Compute to the customer — the rest of the stack stays with the customer.
