The marble texture was generated locally with the SDXL 1.0 model, licensed
under CreativeML Open RAIL++-M:
https://huggingface.co/stabilityai/stable-diffusion-xl-base-1.0/blob/main/LICENSE.md
The book-binding grain, tooled stone relief, steel grime and the three
stained-glass panels were generated locally with the same SDXL 1.0 model.

The pier ornament was generated locally with SDXL 1.0 and ControlNet Union
SDXL, licensed Apache-2.0:
https://huggingface.co/xinsir/controlnet-union-sdxl-1.0

The Hari Seldon statue was generated locally. Z-Image-Turbo drew the concept,
with its Qwen3 4B text encoder, both licensed Apache-2.0:

BiRefNet (MIT) removed the background: https://github.com/ZhengPeng7/BiRefNet
TRELLIS.2 (MIT) turned the image into a mesh:

The palace gardens' images (the palace, the city's towers, the sprigs of
leaves, the clipped box and the bark of the trees and hedges, the grain of the
terrace's stone and paving) were generated locally with the same Z-Image-Turbo
model. BiRefNet cut out the palace and the sprigs. Lotus-D v1.1 depth,
licensed Apache-2.0, with Stability AI's sd-vae-ft-mse, licensed MIT, found
the sky over the city's towers:

The trees, the clipped yews and the hedges' sprays, the self-balancing
scooter, the balusters, pedestals and lanterns are meshes made in Blender by
scripts written for this scene; Blender's Cycles rendered the trees' distant
views.

The people in the gardens (a courtier, a lady, a walker and a gardener, with
no face and no costume from any film or series) are meshes made in Blender by a
script written for this scene; a shader of our own walks them.

The Imperial Palace, the parterre's clipped box and yews, the basin with its
fountain and the city's six landmark towers are meshes made in Blender by
scripts written for this scene; Blender's Cycles baked the palace's light and
rendered the image of it that the canal mirrors. The city's street plan and
the lights of its ground were drawn by a script written for this scene, which
groups the districts and traces the boulevards with IX, the author's own
library: https://github.com/GuitarAlchemist/ix The gardens' ground (gravel,
crushed brick and lawn) and the towers' night facades were generated locally
with the same Z-Image-Turbo model, from text prompts only. The fountain show's
spray texture and the drone's hum were synthesised by scripts written for this
scene.

No model weights are included in this distribution.
