Authentic user-generated content style — see how these models compare with real AI-generated outputs.
Full comparisonCompare Models (select 4)
UGC Creator visuals work best when they look real: natural lighting, imperfect details, believable environments, and “shot-on-phone” vibes that feel like everyday content—not a polished campaign. Flux 2 and Seedream 4.5 both generate strong UGC-style images in Influencer Studio, but they approach realism, editing, and repeatability differently.
Below is a practical comparison focused on authentic UGC output: how quickly you can get a believable creator look, how well each model handles edits and variations, and what you get for the credits you spend.
UGC Creator — Side-by-Side Results
Prompt
"A 20s UGC creator with shoulder-length wavy dark hair in a cropped hoodie and high-waisted leggings holds a skincare serum up near her face while filming on her phone, glancing slightly off to the lens like she’s mid-sentence. Casual bathroom/bedroom vanity setup with a slightly messy countertop, warm morning window light, handheld front-camera vibe with natural skin texture and minimal makeup. Candid “first impressions” moment, not posed, like a TikTok review screenshot."

Flux 2 Strengths
- LoRA support for repeatable UGC looks (consistent creator identity, wardrobe, or brand styling across many images)
- Versatile image-to-image editing for iterating on “real” details (background swaps, prop tweaks, framing changes) while keeping the candid feel
- Up to 4MP output for sharper “phone photo” crops, product close-ups, and multi-platform resizing without losing clarity
- Strong style transfer controls to dial in common UGC aesthetics (bathroom mirror selfie, kitchen counter demo, car interior shot)
- Face-swap support for creator-style variants when you need multiple talent options or quick localization
Seedream 4.5 Strengths
- High-quality text-to-image that can quickly land on a believable UGC baseline with minimal prompt complexity
- Strong image-to-image editing for cleanup and refinement (lighting balance, background simplification, composition adjustments)
- Versatile styles for switching between everyday UGC scenarios (unboxing, GRWM, gym mirror, desk setup, street daylight)
- Competitive per-image cost (16 credits) for teams producing many UGC variations or rapid A/B creative testing
Verdict
Choose Flux 2 if your UGC pipeline depends on consistency and control—especially if you want to reuse a specific creator look repeatedly (via LoRA), generate higher-resolution outputs (up to 4MP), or rely on advanced editing options like face-swap and style transfer for scalable variations.
Choose Seedream 4.5 if you want a straightforward, cost-efficient model that produces strong UGC-style images quickly and edits them reliably, without needing fine-tuning workflows. At 16 credits per image, it’s also the simpler pick for high-volume iteration.
