Meta-prompt with long city descriptions (≥12 lines), developed subject lines (≥5 lines), free color-palette invention, and anti-default placement. Documentary realism constraints. Tested October 2026 with Grok expansion and Grok-image rendering.
[META-PROMPT]
Imagine a city in earth hyper-future in 500 000 to 1 M years ahead. Use the following broad principles:
-a city has a location(antigravity city floating in the sky 20%, ground based in a valley landscape 10%, near a sea shore 20%, around a river 15%)
-a city is a collection of heterogeneous artificial structures aimed at various purposes with a communication network.
-futuristic materials : organic self repairing fabric, pearlescent with alveoli, metallic nano-tech materials.
-the city shall have a coherent city style and be aesthetically pleasing while using futuristic materials.
City style suggestions: white, blue and gold with abstract Islamic-inspired forms 10%, iridescent pale white and organic shapes 10%, black, red with gold superstructures 10%.
Color palette invention: For the remaining probability mass, invent original, harmonious limited palettes. Explore unexpected combinations such as mineral greens with warm copper, smoky violet with silver, deep teal with champagne, oxidised turquoise with ivory, amber with graphite, or entirely new combinations. Treat these as inspiration, not a fixed list. Ensure the palette works coherently with the city's materials, lighting, location, and organic or technological character. Avoid defaulting to familiar science-fiction palettes.
Structure the prompt into Scene : with city description. Then Subject : and Style:
For the subject part develop the outfit (purple silk cape with silver decorations 10%, black velvet gold decorated cape 10%) , jewels,
(aluminium self configuring armour interleaved with decorated velvet 10%, cyberpunk decorated outfit 10%, complex & elegant outfit made of unknown materials 20%, white silk with gold decoration 20%).
Probability:
viewpoint : at ground level within the city 33%, on a terrace of a building 33%, from a flying camera 33%.
Guidelines : avoid uniformity, keep the city heterogenous, no recognisable or conventional architecture, no text in the image. Make sure the city description is developed to at least 12 lines.
Make sure the Subject description is developed to at least 5 lines.
Fixed : "Style : photo realistic , widescreen 16:9, documentary shot taken within the city (at ground level within the city 33%, on a terrace of a building 33%, from a flying platform 33%). Documentary realism: The image should feel like an actual photograph taken by an observer visiting this future city, not like concept art or a promotional illustration. Use physically coherent illumination, natural atmospheric perspective, believable material behaviour, subtle imperfections, incidental environmental details, and an observational camera position. Avoid theatrical composition, excessive glow, uniformly pristine surfaces, exaggerated cinematic lighting, and the conventional visual clichés of science-fiction concept art. The city may be extraordinary, but the photograph itself must feel un-stylised and observational.
Subject : An asian cyber princess of immense beauty stand between 2 to 30 meters from the viewer, part machine part human. Place the cyber princess off-center, on (an anti-gravity platform 25%, a building terrace 25%). When placement is not one of the listed options, invent a different position inside the city (ground, walkway, bridge, fragment…). Do not default to a platform or terrace.
