Top-down arranged compositions and aesthetic product flat lays — see how these models compare with real AI-generated outputs.
Full comparisonCompare Models (select 4)
Flat lay images live or die by the details: believable top-down perspective, clean object separation, natural shadows, and styling that feels intentionally arranged rather than randomly scattered. On Influencer Studio, both Flux Ultra 1.1 and Seedream 4.5 can produce high-quality flat lays, but they shine in different parts of the workflow.
Flux Ultra 1.1 focuses on premium, photorealistic generation with ultra-high detail—ideal when you want a “finished” top-down product scene in one prompt. Seedream 4.5 pairs strong generation with image-to-image editing, which is especially useful for iterating on composition, swapping items, or refining layout without restarting from scratch.
Flat Lay — Side-by-Side Results
Prompt
"Top-down flat lay overhead shot on a light wood kitchen table: a 20s woman with shoulder-length wavy brown hair and a cozy oversized grey sweatshirt leans into the frame from the edge, looking up toward the phone camera with a relaxed, just-woke-up expression while her hand reaches for a ceramic mug. A casually styled breakfast scene is neatly arranged—oat milk carton, matcha whisk, small bowl of berries, open journal with messy handwritten to-do list, gold hoops, lip balm, and phone with Instagram Story draft visible—balanced composition on a clean surface. Soft natural window light, slightly imperfect candid vibe like a real UGC morning routine post."

Flux Ultra 1.1 Strengths
- Exceptional micro-detail for flat lays (textures, fabric weave, label edges, subtle surface grain)
- Photorealistic lighting and shadow behavior that helps top-down scenes feel grounded and premium
- Strong material realism (glass, metal, paper, ceramics) for product-centric flat lay compositions
- Crisp, high-end look that works well for ecommerce-style overhead shots and hero images
Seedream 4.5 Strengths
- Image-to-image editing for flat lay iteration (rearrange items, adjust styling, refine spacing) without losing the overall scene
- Versatile style range (clean studio flat lay, lifestyle tabletop, editorial mood boards) from the same base concept
- High-resolution output that holds up for social crops (1:1, 4:5, 9:16) and detail punch-ins
- Practical for “client feedback” workflows—make targeted changes instead of regenerating entirely
Verdict
If your priority is a premium, photoreal flat lay that looks production-ready with minimal iteration, Flux Ultra 1.1 is the stronger pick—especially for product texture fidelity and convincing top-down lighting.
If you expect to iterate on layout (move objects, refine negative space, test alternate props) or you already have a reference flat lay to improve, Seedream 4.5 is often the more efficient choice thanks to its editing workflow. Pricing is identical at 16 credits per image, so the decision typically comes down to “best first-shot realism” (Flux Ultra 1.1) versus “best iteration and control” (Seedream 4.5).
