Full comparisonCompare Models (select 4)
Flux 2 and Seedream 4.5 are two powerful image models in Influencer Studio, but they can feel very different when your goal is true photorealism—hyperrealistic renders that read as real camera photos. This comparison focuses on the details that matter most: natural skin texture, believable lighting, lens-like depth of field, realistic materials, and how well edits hold up without introducing artifacts.
Below, we break down where each model shines for photorealistic workflows, including text-to-image results, image-to-image editing, consistency across variations, and how pricing impacts high-volume production.
Photorealistic — Side-by-Side Results
Prompt
"Hyperrealistic photo of a 22–28-year-old woman with shoulder-length wavy dark brown hair, minimal makeup with natural skin texture, wearing an oversized gray hoodie and black bike shorts, holding her phone at arm’s length and glancing toward the front camera mid-sentence like an Instagram Story. She’s in a bright kitchen with a messy counter (coffee mug, opened cereal box, keys), one hand stirring an iced coffee, morning window light casting soft realistic shadows and true-to-life color. DSLR-quality realism, candid slightly imperfect framing, subtle motion blur in her stirring hand, authentic “UGC morning routine” vibe (not editorial, not cinematic)."

Flux 2 Strengths
- LoRA support for photorealistic consistency (e.g., locked-in identity, wardrobe, or product look across shoots)
- Up to 4MP output for crisp, camera-like detail in skin texture, hair, fabrics, and small product features
- Versatile image-to-image editing for targeted photoreal changes (pose, background, lighting mood) while preserving realism
- Style transfer and face-swap support for controlled, photo-like variations and campaign adaptations
Seedream 4.5 Strengths
- Strong photoreal output with reliable results from simple prompts, especially for clean commercial and lifestyle imagery
- Effective image-to-image editing for realistic refinements without heavy prompt engineering
- High-resolution generation suitable for social, web, and many ad placements where “photo credibility” matters
- Cost-efficient at 16 credits per image for iterative photoreal exploration and batch generation
Verdict
If your photorealistic workflow depends on repeatability—keeping the same subject identity, product geometry, or brand look consistent across many images—Flux 2 is typically the better fit thanks to LoRA support and its high-detail 4MP output. It’s particularly strong when you need a controlled “photoshoot series” feel rather than one-off hero images.
If you want high-quality photoreal images quickly and at a lower per-image cost, Seedream 4.5 is a compelling choice for everyday production. It’s well-suited to fast iteration and broad photoreal styles, especially when you don’t need custom fine-tuning for consistency.
