In Influencer Studio, Flux Ultra 1.1 and Seedream 4.5 are both premium options priced at 16 credits per image, but they excel in different parts of a headshot workflow.
Below is a focused comparison for corporate and professional headshot photography—covering photoreal fidelity, consistency, retouch-like polish, background control, and how easy it is to iterate toward “LinkedIn-ready” results.
Professional Headshot — Side-by-Side Results
Prompt
"A candid, selfie-style professional headshot of a 25–32-year-old woman with shoulder-length dark brown hair (soft waves), wearing a smart-casual blazer over a plain white tee, holding her phone slightly above eye level and looking near the camera with a relaxed, confident half-smile. She’s standing by a bright café window with a clean, muted light-grey wall behind her (simple uncluttered background), natural daylight as key light with soft shadows, minimal makeup, subtle earrings, authentic “just stepped in for a coffee” vibe like an Instagram story thumbnail. Crisp, realistic smartphone photo look, no editorial posing, no dramatic styling."

Flux Ultra 1.1 Strengths
- Outstanding micro-detail for headshots (skin texture, hair strands, fabric weave) with a high-end, photoreal finish
- Strong studio-portrait look with convincing lighting and depth (clean separation, realistic shadows, natural specular highlights)
- Produces premium-looking results quickly when you have a clear prompt and want a “final” image with minimal iteration
- Excellent for crisp corporate aesthetics: sharp eyes, refined contrast, and high perceived resolution
Seedream 4.5 Strengths
- Image-to-image editing makes it easier to refine an existing headshot (adjust background, wardrobe, crop, or overall polish) without restarting
- Versatile styling for different corporate needs (traditional studio, modern startup, editorial, or softer lifestyle headshot looks)
- Efficient iteration for consistency across a team: you can evolve a preferred look and keep adjusting toward a uniform brand standard
- High-quality output with strong control for practical headshot fixes (background cleanup, light rebalancing, and subtle variations)
Verdict
Choose Flux Ultra 1.1 when your priority is maximum photoreal detail and a premium, studio-finished headshot straight from text-to-image—ideal for standout executive portraits and crisp corporate profiles.
Choose Seedream 4.5 when your workflow benefits from editing and iterative refinement—especially if you need to standardize headshots across multiple people, update an existing image, or quickly test background/wardrobe variations while keeping a consistent professional look. Since both cost 16 credits per image, the best value depends on whether you need “best-in-class generation” (Flux Ultra 1.1) or “best-in-class refinement” (Seedream 4.5).
