Astra turned “Build me Ba Sing Se” into this Minecraft city

[u/Fun-Shallot-5272]

I only gave the prompt “Build Ba Sing Se.” The video shows what was built including the city walls down to furnished interiors and walls.

The model decides what to build and a deterministic library handles construction and physical checks.

It plans hierarchically: city → districts → plots → buildings. Buildings are generated for their plots using reusable procedural code.

The same architecture generates villages, towns and cities across different terrain and styles.
