Full comparisonCompare Models (select 4)
Choosing the right model for professional headshots comes down to three things: believable facial detail, controlled studio lighting, and consistency across a corporate look (wardrobe, background, and framing). Flux Ultra 1.1 and GPT-Image 1.5 both target high-quality image generation, but they excel in slightly different parts of the headshot workflow.
Below is a focused comparison for corporate and professional headshot photography, including how each model handles photorealistic skin texture, hair edges, suit fabrics, neutral backgrounds, and “brief-following” (pose, expression, crop, and lighting). We also break down credit costs so you can match quality needs to budget.
Professional Headshot — Side-by-Side Results
Prompt
"A late-20s woman with shoulder-length dark brown hair in a neat blowout wears a smart-casual navy blazer over a plain white tee, holding her phone at arm’s length and looking just off-camera with a relaxed, confident half-smile. She’s in a quiet coworking café corner with a clean matte light-grey wall behind her (no décor), laptop barely peeking into frame for an everyday “quick LinkedIn update” vibe. Soft natural window light from the side, front-facing phone camera selfie, minimal touch-up realism."

Flux Ultra 1.1 Strengths
- Exceptional photorealism for corporate headshots, with crisp micro-detail in skin, hair, and fabric textures
- Premium-looking studio output: clean tonal range, realistic specular highlights, and polished overall finish
- Strong results for close-cropped head-and-shoulders framing where detail and realism are most noticeable
- Consistently high perceived quality per image—useful for executive or client-facing headshot deliverables
GPT-Image 1.5 Strengths
- Strong prompt adherence for headshot requirements (crop, background color, wardrobe notes, expression, lighting direction)
- Flexible quality tiers (low/medium/high) to balance iteration speed with final delivery needs
- Reliable for producing specific “briefed” variations (e.g., neutral smile vs. serious, gray vs. white backdrop, different tie colors)
- Good all-around fidelity for corporate headshots, especially when you need controlled composition and repeatable specs
Verdict
If your priority is the most premium, photorealistic headshot finish—particularly for executive portraits where skin texture, hairline edges, and suit fabric realism matter—Flux Ultra 1.1 is a strong pick at 16 credits per image.
If you need tight control over the brief (exact crop, background, wardrobe, expression) and want pricing flexibility for drafts versus finals, GPT-Image 1.5 is often the more efficient workflow: generate fast iterations at 8 credits, then move to 16 or 32 credits for the final, most polished selects.
