Full comparisonCompare Models (select 4)
Flux Ultra 1.1 and GPT-Image 1.5 are both strong options in Influencer Studio for e-commerce photography, especially when you need product-on-model shots and clean, conversion-focused imagery for online stores. They differ most in how they balance photorealistic detail, prompt precision, and cost control.
Below is a practical comparison focused on common storefront needs: consistent apparel fit, accurate product presentation, believable skin and fabric texture, simple studio backdrops, and producing multiple variations (angles, poses, colorways) without losing brand consistency.
E-commerce Photography — Side-by-Side Results
Prompt
"A mid-20s woman with shoulder-length wavy brown hair in a casual oversized oatmeal hoodie and black leggings holds a reusable insulated tumbler (the product) close to her face while looking slightly off-center toward the phone camera, like she’s filming an Instagram story “morning coffee” check-in. Shot in a bright kitchen with a mostly clean white counter and a few everyday items softly blurred behind her; natural window light, catalog-ready clarity with a subtle “multiple angles” feel (one hand showing the lid, then the full cup). Casual handheld phone-camera framing, authentic expression, minimal retouching, e-commerce product photo vibe suitable for a Shopify listing."

Flux Ultra 1.1 Strengths
- Exceptional photorealism for premium product-on-model hero images (skin, fabric, stitching, and material texture)
- Ultra-high detail that helps products feel tangible in close-ups (weave patterns, leather grain, reflections)
- High-end studio look well-suited to luxury and premium storefront positioning
- Strong performance for clean backgrounds and polished lighting that reads as professional catalog photography
GPT-Image 1.5 Strengths
- Strong prompt adherence for specific e-commerce requirements (pose, framing, background, styling, negative constraints)
- Versatile output for generating many listing variations quickly (angles, crops, lifestyle vs studio, seasonal sets)
- Tiered quality options (low/medium/high) to match the task—drafts, iteration, and finals—within a credit budget
- Reliable for detailed scenes when you need context (props, environments) while keeping the product as the focal point
Verdict
Choose Flux Ultra 1.1 when you’re producing fewer, higher-impact images—especially premium product-on-model hero shots where photorealistic detail and a luxury finish matter most. At 16 credits per image, it’s straightforward for final-quality outputs.
Choose GPT-Image 1.5 when you need tighter control over exact requirements and lots of variations for listings, A/B tests, or multi-SKU catalogs. Its 8/16/32 credit tiers make it easier to iterate cheaply and reserve the higher tier for final storefront-ready selects.
