Professional Headshot — Side-by-Side Results
Prompt
"A candid phone-camera head-and-shoulders shot of a 20s–30s influencer with shoulder-length dark brown hair in a low ponytail, light makeup, wearing a smart-casual blazer over a plain crewneck tee, looking slightly off-center toward the camera with a relaxed, confident half-smile. They’re standing in front of a clean matte light-grey wall near a window in a small home office corner, natural daylight mixing with soft studio-style fill lighting for a crisp “LinkedIn headshot” feel. Subtle imperfections like a visible phone held at chest height and a tiny glimpse of a desk edge keep it authentic and everyday, not editorial."

Flux 2 Strengths
- LoRA support for brand- and role-specific headshot consistency (e.g., company look, repeated wardrobe, lighting style)
- Up to 4MP output for crisp facial detail and clean crops (useful for tight head-and-shoulders framing)
- Versatile image editing (image-to-image) for controlled refinements like background swaps, wardrobe tweaks, and lighting adjustments
- Style transfer to standardize a corporate “house style” across a team while keeping individuals distinct
- Face-swap support for headshot variations when you need to preserve identity across multiple looks (use with appropriate permissions)
Seedream 4.5 Strengths
- Strong editing capability for fast iteration on headshot polish (background, tone, and overall refinement)
- High-quality, high-resolution outputs suitable for professional profile use and marketing placements
- Versatile styles to match different corporate aesthetics (modern tech, traditional finance, creative agency)
- Straightforward pricing at 16 credits per image, helpful for predictable budgeting on batches
Verdict
Flux 2 is the stronger choice when corporate headshots need repeatable consistency across many people or sessions—especially if you plan to use LoRA workflows to lock in a specific brand look (lighting, backdrop, wardrobe vibe) and want up to 4MP output for sharper crops. It’s also well-suited to teams that rely on image-to-image editing and structured variations.
Seedream 4.5 is a great fit for high-quality headshots with efficient iteration and predictable cost. If you’re producing professional portraits without needing LoRA-based standardization, its strong editing and 16-credits-per-image pricing make it a practical option for ongoing headshot generation.
