Prompt

Create an illustration.
Create an original Japanese itasha vehicle based entirely on the uploaded illustration. Design a fully fictional vehicle and manufacturer naturally born from the artwork's universe, never resembling any real vehicle or brand.
First, carefully analyze the uploaded illustration and determine the single most suitable vehicle category. The choice must arise naturally from the character, worldbuilding, culture, technology, architecture, personality, lifestyle, and atmosphere.
The vehicle may be a kei car, hatchback, sedan, wagon, coupe, limousine, SUV, pickup, microvan, camper, utility vehicle, military vehicle, luxury vehicle, retro-futuristic vehicle, magical vehicle, or another original type. Never default to the same vehicle category. Each illustration must begin from a completely blank design process and produce a vehicle with a unique body architecture, proportions, roofline, cabin position, and driving purpose. Sports cars, race cars, GT cars, and supercars must only be chosen when the uploaded illustration clearly and naturally requires them.
The body shape, proportions, cockpit, wheels, lighting, materials, interior, and every design detail must naturally evolve from the illustration's atmosphere, colors, fashion, architecture, magic, technology, and worldbuilding.
All decals, logos, symbols, typography, crests, and sponsor-style graphics must be completely original fictional designs inspired only by the uploaded illustration.
If a character exists, preserve the original face, hairstyle, clothing style, colors, proportions, and personality, and place the character naturally beside or interacting with the vehicle.
Compose the illustration in a vertical 9:16 format. The full vehicle must remain visible while the character becomes the primary focal point. Use a dramatic low-angle perspective that emphasizes both the character and the vehicle, creating a powerful smartphone wallpaper composition.

Cinematic automotive photography, anime-inspired photorealism, masterpiece quality, ultra detailed, dynamic lighting, dramatic reflections, no watermark.

  • Cross-model retest: the recommended model is GPT Image 2, and this run used Grok Imagine. The result shows how the same prompt carries over to Grok Imagine; it does not show what the creator got with the original model.
  • The retest score is the mean of two AI judges (0–100) for this single generation. No person has reviewed it, and it is not a success rate.

The requested model is recorded, but the generation receipt did not expose a verifiable underlying model ID.
