Same prompt, both models
The identical prompt, rendered by Leonardo AI and Stable Diffusion 3.5. Only verified outputs are shown — never another model's work.
“A neon-lit street at night, slow forward dolly, rain-slick reflections, cinematic”
“Close-up portrait turning toward camera, soft key light, shallow depth of field”
“Aerial drone gliding over a landscape at golden hour, long shadows”
“Product on a reflective surface, slow rotation, studio gradient light”
