Full comparisonCompare Models (select 4)
Choosing the right model for a LinkedIn Professional Photo comes down to three things: credible facial realism, business-appropriate styling (wardrobe, grooming, background), and the ability to refine details without making the portrait look “generated.” Both Flux 2 and Seedream 4.5 can produce polished, modern headshots, but they excel in different parts of the workflow.
Below is a practical comparison focused on corporate-ready portraits—clean lighting, natural skin texture, accurate facial features, and subtle retouching—plus how much each option costs per image on Influencer Studio.
LinkedIn Professional Photo — Side-by-Side Results
Prompt
"A candid phone-camera portrait of a 28–35-year-old professional influencer with shoulder-length dark hair, light natural makeup, wearing a tailored navy blazer over a simple white tee and slim black trousers, holding their phone slightly off to the side while looking near the lens with an approachable, confident smile. Shot in a real coworking space corner with a neutral wall, a desk and laptop softly blurred behind them, morning window light (no harsh shadows), clean and LinkedIn-appropriate like an Instagram story “on my way to a client call” selfie. Natural, unposed posture, realistic skin texture, minimal background clutter, professional but everyday vibe."

Flux 2 Strengths

- Style transfer and face-swap support for controlled variations (e.g., updating attire or background while keeping the same face structure)
- Two pricing tiers (Standard 22 credits, Klein 9B 16 credits) to balance quality vs cost depending on the project
Seedream 4.5 Strengths
- Strong out-of-the-box quality for clean, professional portraits with minimal prompting and fewer iterations
- Versatile editing capabilities for quick improvements (background cleanup, lighting tweaks, and subtle polish)

- Reliable style range for corporate looks (neutral backdrops, natural light, and modern office aesthetics)
- Straightforward pricing at 16 credits per image for predictable budgeting
Verdict
Pick Flux 2 if your LinkedIn headshots need maximum control and consistency—especially when you’re matching a brand look across multiple portraits, doing iterative image-to-image refinement, or relying on LoRA-based repeatability. It’s also a strong fit when you need higher-detail exports (up to 4MP) and more specialized tools like face-swap for controlled variations.
Pick Seedream 4.5 if you want fast, high-quality professional portraits with less setup and a simple cost structure. For many single-person LinkedIn updates, it delivers polished results at a predictable 16 credits per image, making it a solid default for efficient headshot generation.
