Full comparisonCompare Models (select 4)
Seedream 4.5 and Z-Image Turbo are both strong options in Influencer Studio for creating stock-photography style visuals—clean, versatile, and suitable for broad commercial use cases like blogs, ads, landing pages, and product storytelling. The key difference is emphasis: Seedream 4.5 prioritizes higher-end output and robust editing, while Z-Image Turbo focuses on speed and cost efficiency.
For stock imagery, the practical questions are less about “wow factor” and more about consistency, realism, neutral styling, and how quickly you can iterate on variations (poses, backgrounds, crops, and seasonal updates) without introducing artifacts. Below is a focused comparison based on common stock-photo workflows.
Stock Photography — Side-by-Side Results
Prompt
"A diverse woman in her mid-20s with shoulder-length curly hair, wearing a casual oversized hoodie and high-waisted leggings, holds her phone slightly above eye level for a candid selfie while looking near the camera with a relaxed half-smile. She’s in a bright neighborhood café by a window with a latte and open laptop on the table, background softly showing other patrons and simple décor. Clean stock-photo composition with even natural window light, realistic smartphone perspective, unposed “quick Instagram story check-in” vibe."

Verdict
Choose Seedream 4.5 when you need premium, versatile stock-photo realism and expect to do meaningful edits—cleaning up scenes, adjusting details, and producing multiple licensable variations from a strong base image. It costs more per render (16 credits), but can reduce rework when quality and polish are the priority.
Choose Z-Image Turbo when your stock workflow is volume-driven: generating many options quickly, building large sets on a budget, or using LoRA-driven consistency for repeatable campaigns. At 8 credits per image, it’s a practical choice for fast iteration and cost-effective production, especially when “standard quality” is sufficient.
