Stock Photography — Side-by-Side Results
Prompt
"A diverse woman in her late 20s with shoulder-length wavy dark hair, wearing a beige hoodie and high-waisted light-wash jeans, holds her phone slightly above eye level for a casual selfie and looks near the camera with a relaxed half-smile. She’s seated at a bright neighborhood café by a window with a latte and an open laptop on the table, background softly showing other patrons and menu boards. Natural daylight from the window, clean stock-photo composition, realistic smartphone-camera feel like an Instagram story."

- Versatile image-to-image editing tools for stock workflows (refining composition, swapping backgrounds, adjusting styling while keeping realism)
- Up to 4MP output for sharper stock deliverables and more cropping flexibility
- Style transfer options that can help match a client’s existing stock library aesthetic without over-stylizing
- Face-swap support for controlled talent variations when you need consistent, non-identifying lifestyle imagery
Seedream 4.5 Strengths
- Strong all-around text-to-image quality for clean, modern stock compositions across multiple categories
- High-resolution output geared toward crisp, detail-rich stock visuals

- Straightforward pricing at 16 credits per image, making large stock batches easier to budget
Verdict
If your stock photography workflow depends on repeatable brand consistency—like producing a cohesive pack of images for a campaign, marketplace listing set, or a long-running content series—Flux 2 stands out thanks to LoRA support, solid editing flexibility, and up to 4MP output. It’s especially useful when you need the same “house style” to hold across many prompts and revisions.
If you want a simple, cost-efficient model that delivers strong, versatile stock visuals with minimal setup, Seedream 4.5 is a great default choice. At 16 credits per image, it’s often the better fit for high-volume stock generation where speed, broad style coverage, and predictable budgeting matter most.
