On Influencer Studio, Flux Ultra 1.1 and GPT-Image 1.5 both generate high-quality portraits from text prompts, but they differ in how they handle realism, control, and cost.

LinkedIn Professional Photo — Side-by-Side Results
Prompt
"A candid phone-camera selfie of a 30–40-year-old professional influencer with neat shoulder-length dark hair, light natural makeup, wearing a navy blazer over a simple white tee and tailored trousers, holding a laptop sleeve and coffee cup while looking near the camera with an approachable confident smile. Shot in a real coworking café corner with a neutral wall and a small plant in the background, slightly off-center framing like an Instagram story thumbnail, natural window light with soft indoor fill. Authentic everyday vibe—mid-step, keys on a lanyard visible, nothing overly posed or editorial."

Flux Ultra 1.1 Strengths
- Exceptional photorealism for headshots, with crisp facial detail and refined skin texture when prompts specify natural retouching
- Premium-looking lighting and depth that can resemble studio portraiture (soft key light, subtle rim light, realistic shadows)
- High-detail output that holds up well for LinkedIn crops (1:1 or 4:5) without the face looking “soft” or overly processed
- Strong results for classic corporate aesthetics: neutral backdrops, tailored suits, and polished yet believable finishes
GPT-Image 1.5 Strengths
- Strong prompt adherence for business constraints (e.g., “no heavy makeup,” “neutral background,” “conservative suit,” “no props,” “no dramatic lighting”)
- Versatile quality tiers (8/16/32 credits) for quick drafts vs. final LinkedIn-ready renders
- Reliable control over composition and styling details (framing, wardrobe color, background tone, expression) when prompts are specific
- Good fidelity for professional portrait variations (different outfits/backgrounds) while staying aligned to the requested corporate look
Verdict
If your priority is a premium, photorealistic LinkedIn headshot with studio-like polish, Flux Ultra 1.1 is the stronger pick—especially when you want maximum facial detail and a high-end finish at a predictable cost (16 credits per image).
If you care most about following exact LinkedIn-safe instructions (wardrobe rules, background requirements, expression, framing) and want flexible budgeting across drafts and finals, GPT-Image 1.5 is a practical choice—use low/medium for iteration and high when you need the cleanest, most controlled final output.
