Flat Lay — Side-by-Side Results
Prompt
"Top-down flat lay shot on a sunlit café table: a 20s woman with shoulder-length wavy brown hair leans into the edge of frame looking up toward the phone camera, wearing a cozy cream knit sweater and simple gold hoops, mid-reach for her iced latte like she’s filming a quick “coffee break” story. Neatly arranged around her are a croissant on parchment, sunglasses, a lip balm, a small notebook with a pen, and her phone with the camera app open, all on a clean light-wood surface with soft, even natural window light. Authentic, casual UGC vibe—slight imperfections like a few crumbs and a folded receipt for realism."

Flux Ultra 1.1 Strengths
- Exceptional micro-detail for flat lays (textures like linen, matte paper, wood grain, and subtle scuffs read convincingly)
- Highly photorealistic lighting and shadows, useful for premium product flat lays and editorial-style compositions
- Strong material rendering (glass, metal, glossy packaging) that helps items feel “placed” rather than floating
- Premium polish for hero images where realism and crispness are the priority
GPT-Image 1.5 Strengths
- Strong prompt adherence for precise flat lay layouts (specific object counts, positions, spacing, and styling rules)
- Versatile output across styles (minimalist, colorful, lifestyle, seasonal) while maintaining high fidelity
- Flexible quality tiers (8/16/32 credits) to balance iteration speed vs final-detail renders
- Reliable for repeatable series: consistent composition instructions and scene requirements across multiple generations
Verdict
Choose Flux Ultra 1.1 when your flat lay needs premium photorealism—high-end product shots, editorial textures, and crisp lighting that sells “real camera” credibility. At 16 credits per image, it’s a straightforward pick for final assets and hero visuals.
Choose GPT-Image 1.5 when layout control and repeatability matter most—especially if you’re building a flat lay content system (same template, new products) or need fast iteration. Its 8/16/32 credit tiers make it easier to draft compositions cheaply and reserve high-cost renders for the final selects.
