Flat lay content lives or dies by composition: clean top-down perspective, intentional spacing, consistent shadows, and a cohesive styling story. In Influencer Studio, Seedream 4.5 and Z-Image Turbo both support text-to-image flat lays, but they differ in how precisely they handle arrangement, refinements, and repeatable aesthetics.
Below is a practical comparison focused on common flat lay needs—product grids, lifestyle spreads, seasonal kits, and brand mood boards—covering composition reliability, edit workflows, speed, and credits per image.
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."

Seedream 4.5 Strengths
- Stronger flat-lay composition fidelity for tidy top-down layouts (clean spacing, fewer awkward overlaps)
- More reliable refinement via image-to-image editing—useful for nudging object positions, removing clutter, and correcting small styling issues
- Higher perceived detail for product surfaces (labels, textures, packaging) and more polished lighting/shadow transitions
- 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
- LoRA support can help lock in a consistent flat-lay look (brand palette, tabletop material, prop style) across batches
- Solid baseline text-to-image and image-to-image for straightforward top-down arrangements without heavy retouching
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.
Choose Z-Image Turbo when speed and volume matter most. For quick flat-lay concepting, prop exploration, and generating many variations on a theme—especially when paired with LoRA for consistent styling—it delivers strong value at half the per-image cost.
