Flux Ultra 1.1 vs GPT-Image 1.5
Skincare, makeup looks, and beauty content — see how these models compare with real AI-generated outputs.
Full comparisonCompare Models (select 4)
Choosing the right image model for beauty content comes down to two priorities: how convincingly it renders skin, and how reliably it follows your creative direction. In Influencer Studio, Flux Ultra 1.1 and GPT-Image 1.5 both produce high-quality beauty imagery—but they excel in different parts of the workflow.
This comparison focuses on skincare visuals, makeup looks, and beauty campaign assets—where texture realism (pores, glow, foundation finish), shade accuracy (lip and blush tones), and consistency (repeatable looks across a set) matter most.
Beauty & Makeup — Side-by-Side Results
Prompt
"A candid front-facing phone camera shot of a 22–28-year-old woman with shoulder-length wavy dark brown hair, wearing an oversized grey hoodie and minimal jewelry, sitting on her bed in a slightly messy bedroom vanity corner. She’s looking near the camera while tapping concealer under one eye with a damp sponge, dewy skin and soft peach blush already on, with a small lineup of skincare + makeup (tinted moisturizer, concealer, cream blush, lip oil) neatly arranged on the vanity. Natural window light mixed with a gentle ring-light glow, casual “get ready with me” vibe like an Instagram story."

Flux Ultra 1.1 Strengths
- Exceptional photorealism for skincare close-ups (natural pores, specular highlights, dewy vs matte finish)
- Ultra-high detail suited to editorial beauty shots and premium campaign imagery
- Strong rendering of makeup textures (gloss, shimmer, metallics) with convincing light interaction
- Great for “hero” images where realism and polish are the top priority
GPT-Image 1.5 Strengths
- Strong prompt adherence for specific makeup directions (shade names, placement, finish, and styling notes)
- Versatile output across beauty formats (product + model scenes, lifestyle vanity setups, step-by-step look concepts)
- Quality options (low/medium/high) let you balance iteration speed with final-detail needs
- Reliable for generating multiple concept variations while keeping the brief intact
Verdict
Flux Ultra 1.1 is the better pick when your beauty content depends on premium, photoreal skin and makeup texture—think skincare “glass skin” close-ups, foundation finish comparisons, and high-end editorial portraits. At 16 credits per image, it’s straightforward for final selects and hero assets.
GPT-Image 1.5 is the better all-rounder for beauty teams that iterate often and need the model to follow precise makeup briefs. Its tiered pricing (8/16/32 credits) makes it practical for quick concepting on low, then switching to high for final outputs when detail and fidelity matter most.
