Stock Photography — Side-by-Side Results
Prompt
"A diverse woman in her late 20s with shoulder-length curly dark hair, wearing a casual beige hoodie and black leggings, holds her phone at arm’s length and looks near the camera with a relaxed half-smile while walking through a sunny neighborhood street. Candid influencer vibe like an Instagram Story, one hand holding an iced coffee, crosswalk and storefronts softly blurred in the background, bright even natural daylight and clean stock-photo composition. Shot on a front-facing smartphone camera feel, minimal retouching, authentic everyday moment."

- Flexible credit tiers (8/16/32) for fast iteration vs higher-detail finals depending on your shot list
Seedream 4.5 Strengths
- Best choice when you need image-to-image editing to refine a stock candidate (swap background, adjust framing, iterate on a selected winner)
- High-resolution output suited to stock use cases that demand crisp detail and cleaner edges
- Versatile styles for covering multiple stock libraries (lifestyle, editorial-leaning, minimal product scenes, seasonal themes)
- Predictable per-image pricing (16 credits) that’s easy to budget for standard deliverables
