Prompt
"A diverse woman in her mid-20s with shoulder-length curly hair, wearing a casual oversized hoodie and high-waisted leggings, holds her phone slightly above eye level for a candid selfie while looking near the camera with a relaxed half-smile. She’s in a bright neighborhood café by a window with a latte and open laptop on the table, background softly showing other patrons and simple décor. Clean stock-photo composition with even natural window light, realistic smartphone perspective, unposed “quick Instagram story check-in” vibe."

Verdict
Choose Seedream 4.5 when you need premium, versatile stock-photo realism and expect to do meaningful edits—cleaning up scenes, adjusting details, and producing multiple licensable variations from a strong base image. It costs more per render (16 credits), but can reduce rework when quality and polish are the priority.
Choose Z-Image Turbo when your stock workflow is volume-driven: generating many options quickly, building large sets on a budget, or using LoRA-driven consistency for repeatable campaigns. At 8 credits per image, it’s a practical choice for fast iteration and cost-effective production, especially when “standard quality” is sufficient.
