Flat Lay — Side-by-Side Results
Prompt
"Top-down flat lay on a white duvet in a small bedroom: a 20s woman with shoulder-length wavy brown hair in an oversized gray hoodie leans into frame from the top edge, looking up toward the phone camera with a relaxed, just-woke-up expression while reaching for her iced coffee. Aesthetic overhead arrangement of an open planner, pastel highlighters, lip balm, AirPods, a matcha powder tin, and a slightly messy skincare trio, balanced and casual on the sheet. Soft natural window light, subtle shadows, real Instagram-stories vibe with a little lived-in clutter."

- Versatile styling range for flat lays (minimal studio, cozy lifestyle, editorial, color-blocked brand palettes)
Z-Image Turbo Strengths
- Ultra-fast flat lay generation for rapid iteration on layout ideas and prop combinations
- Cost-effective at 8 credits per image—better for high-volume mood boards and A/B testing compositions

Verdict
Choose Seedream 4.5 when the flat lay needs to look “final”—clean geometry, premium lighting, and the ability to edit toward a precise arrangement. It’s better suited to hero images, product launches, and polished carousel covers where small composition flaws are noticeable.
