Professional Headshot — Side-by-Side Results
Prompt
"A candid smartphone portrait of a 20s–30s influencer with shoulder-length wavy brown hair, light natural makeup, wearing a smart-casual blazer over a plain white tee, looking slightly off-center toward the camera with a relaxed half-smile as if filming an Instagram story. Shot against a clean muted light-gray wall in a real apartment hallway, minimal clutter, soft window daylight from the side for a professional headshot feel while still everyday and approachable. Vertical 9:16, subtle imperfections like a tiny stray hair and natural skin texture, no heavy retouching."

Flux Ultra 1.1 Strengths
- Exceptional micro-detail for skin texture, hair strands, and fabric (suits, blazers), producing a premium headshot finish
- Highly photorealistic lighting and facial rendering that tends to read as “studio-grade” with fewer telltale artifacts
- Strong clarity at high resolution—useful for tight crops, profile avatars, and print-ready team pages
- Best fit when you want fewer retries and a consistently polished corporate look (at a higher per-image cost)
Grok Imagine Strengths
- Cost-efficient at 4 credits per image, making it practical for batch generation (teams, departments, multiple outfits)
- Image-to-image support helps when you want to refine an existing headshot concept, pose, or background direction
- Solid photorealistic quality with flexibility for varied compositions (different office backdrops, lighting moods, framing)
- Great option for rapid iteration—testing hairstyles, wardrobe colors, and background styles without high credit burn
Verdict
Flux Ultra 1.1 is the better pick when the priority is a premium, high-fidelity corporate headshot—crisp facial detail, clean wardrobe rendering, and a more “finished” studio portrait look. It’s well-suited for executive portraits, hero images, and any scenario where you’d rather pay more per image to reduce rerolls.
Grok Imagine is the value leader for professional headshots, especially when you need volume or want to iterate quickly. Its image-to-image capability is a practical advantage for refining a chosen direction, and the lower credit cost makes it ideal for generating consistent team sets—provided you’re comfortable doing a bit more selection and refinement.
