GPT-Image 1.5 vs Z-Image Turbo
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 content lives or dies by composition: clean top-down geometry, believable shadows, consistent materials, and styling that feels intentionally arranged rather than randomly scattered. In Influencer Studio, both GPT-Image 1.5 and Z-Image Turbo can produce aesthetic flat lays, but they differ in how they handle detail, control, and iteration speed.
This comparison focuses on the practical needs of flat lays—product grids, desk setups, recipe ingredient spreads, fashion accessories, and branded content—looking at prompt adherence, consistency across variations, and how quickly you can refine a layout to match a specific art direction.
Flat Lay — Side-by-Side Results
Prompt
"Top-down flat lay photo taken on a phone camera: a 20s woman with shoulder-length wavy brown hair, wearing an oversized gray sweatshirt (her face naturally peeking into the corner, looking up toward the camera with a relaxed, candid expression) beside an aesthetically arranged spread on a white duvet—oat milk latte in a mug, open journal with a pen, phone showing a TikTok draft screen, claw clip, lip balm, and a small croissant on a napkin. Cozy bedroom “Sunday reset” vibe, slightly messy but intentional layout, soft window daylight, realistic shadows and everyday textures (wrinkled sheets, coffee ring on the mug). Authentic influencer story feel, not polished or editorial."

GPT-Image 1.5 Strengths
- Stronger prompt adherence for precise top-down composition notes (e.g., spacing, symmetry, negative space, and object counts)
- Higher-fidelity textures and materials that matter in flat lays (paper grain, fabric weave, metal reflections, packaging finishes)
- Better handling of dense, detailed scenes (many small props) while keeping the arrangement readable
- More reliable lighting and shadow coherence for “studio tabletop” aesthetics, reducing the need for rerolls
- Flexible output quality tiers (8/16/32 credits) for quick drafts vs. premium hero images
Z-Image Turbo Strengths
- Ultra-fast generation for rapid flat lay iteration—great for testing multiple layouts, palettes, and prop combinations
- Cost-effective predictable pricing (8 credits per image) for high-volume concepting and moodboard exploration
- Image-to-image support to refine an existing flat lay (tighten spacing, adjust styling, or shift color mood without starting over)
- LoRA support for consistent brand styling (e.g., recurring packaging look, tabletop textures, or a signature prop set)
- Strong choice for standardized “good quality” flat lays when speed and throughput matter most
Verdict
Choose GPT-Image 1.5 when the flat lay needs to be camera-ready: crisp product edges, premium material realism, and tight adherence to layout instructions (especially for hero images, ads, and detailed prop styling). The quality tiers also make it easy to draft cheaply, then upscale the same concept for final delivery.
Choose Z-Image Turbo when you’re iterating fast or producing lots of variations: it’s well-suited to exploring multiple top-down arrangements quickly, leveraging image-to-image to “nudge” an existing composition, and using LoRA to keep a consistent brand look across a series.
