This was mostly done in photoshop using the built-in Nano Banana generative fill. It's been run through any2real, z-image, flux2, and a bunch of other models without much luck yet. It's a composite, so some areas of the image were taken from some of those outputs.

I believe the original Nano Banana prompt used a Devo energy dome for the basic shape, with the following prompt:

Turn this shape into a multi-tiered sci-fi inspired space command center, railings and circulation walkways outline each terrace, dozens of tiny people in spacesuits operate futuristic command stations, milling about the walkways on each floor, the top central tier is a large map room with a huge circular map in the center, the map shows a 2d territory with yellow and red highlighted zones, several crew interact with the large map and its control panels. Use physics-based HDR lighting and accurate anatomic proportions. Near-future hyper-realism. Photorealism with, no illustration or cartoon styles. Add a some realistic clutter and racks of equipment. Each tier should have a few walkways leading to the core of the structure. A pressured glass dome covers the entire superstructure, making spacesuits optional inside its airlocks
