47%GPT 6 Astra
The green body, black roof and trim, sedan layout, rear lip spoiler and paired exhaust details capture the target’s broad appearance. However, the slab-sided body, flat overhanging roof, open side windows, small wheels and rectangular grille and lights miss the RS 3’s curved proportions and distinctive angular front and rear styling.
46%Claude Fable 5.1
Bright green body with black roof, black lower bumpers, red tail lights and a dark front grille give the right basic colour scheme and a sedan-like three-box silhouette, but the cabin is open-sided with no side glass or proper pillars, the body is boxy and slab-sided, and the distinctive RS 3 details (wide single-frame hexagonal grille, flared arches, slim LED lamps) are only crudely suggested.
42%Claude Opus 5.5
The bright green sedan colour, black roof, black grille between white headlights, red tail lights and a three-box sedan layout loosely match the RS 3. However, the model is very boxy: the roof is a flat, overhanging slab with open sides and no side windows, the glass sits recessed, the wheels are small grey rims, and the side profile lacks the car's sleek sloping roofline.
