Full comparisonCompare Models (select 4)
Creating convincing UGC (user-generated content) visuals is less about “perfect” images and more about believable moments: natural lighting, realistic environments, casual framing, and product-in-hand shots that feel like they came from a real creator.
Seedream 4.5 and Z-Image Turbo both support text-to-image and image-to-image workflows inside Influencer Studio, but they differ in what they optimize for. Seedream 4.5 leans into higher-quality output and stronger editing control, while Z-Image Turbo prioritizes speed, cost efficiency, and LoRA-driven consistency for repeatable UGC looks.
UGC Creator — Side-by-Side Results
Prompt
"A 20s woman with shoulder-length wavy brown hair in a cozy oversized gray hoodie and biker shorts holds her phone at arm’s length, looking slightly off-camera mid-sentence like she’s filming a quick “morning routine” TikTok. She’s in a small, slightly messy kitchen with a coffee maker and cereal boxes visible, one hand stirring an iced coffee in a mason jar on the counter. Soft natural window light, casual phone-camera quality with a tiny bit of grain and imperfect framing, authentic UGC ad vibe."

Seedream 4.5 Strengths
- Higher-quality output that helps UGC scenes look clean while still natural (skin texture, fabric detail, indoor lighting)
- Stronger image-to-image editing for refining “creator realism” (adjusting framing, background clutter, product placement) without restarting
- Versatile style handling for different UGC sub-genres (bathroom mirror selfie, kitchen counter demo, unboxing flat-lay, coffee shop lifestyle)
- High-resolution generation that holds up for ads, product pages, and crops across multiple placements
Z-Image Turbo Strengths
- Ultra-fast generation for rapid UGC iteration (many angles, outfits, rooms, and hooks in one session)
- Lower cost per image (8 credits) for high-volume testing of UGC concepts and variations
- LoRA support for consistent creator aesthetics (repeatable faces, wardrobe vibe, room style, or brand look across a campaign)
- Solid standard-quality output that’s often “good enough” for authentic, slightly imperfect UGC feeds
Verdict
If your UGC workflow relies on refining a base image into multiple polished deliverables—tightening product visibility, fixing small realism issues, and exporting higher-res assets—Seedream 4.5 is the better fit thanks to its quality and editing strength (16 credits/image).

Many teams use Z-Image Turbo for exploration and volume, then switch to Seedream 4.5 for final selects that need extra realism and detail.
