E-commerce Photography — Side-by-Side Results
Prompt
"A mid-20s woman with shoulder-length wavy dark hair wears a relaxed beige knit sweater and light-wash jeans, holding a minimalist stainless-steel insulated tumbler (logo facing out) while taking a casual mirror selfie and glancing toward the phone camera with a natural half-smile. Shot in a bright, tidy bedroom corner with a clean white wall and a small nightstand, soft window daylight and catalog-ready even lighting, crisp focus like a Shopify lifestyle listing. Include a “multiple angles” feel by framing her full upper body in the mirror while the tumbler is closer to the camera in the foreground for clear product detail."

Seedream 4.5 Strengths

Verdict
Pick GPT-Image 1.5 when you’re generating product-on-model images from scratch and want tight prompt control, realistic detail, and consistent e-commerce composition across many SKUs. Its tiered pricing can be cost-effective for early drafts and rapid concepting.
