Full comparisonCompare Models (select 4)
Pet photography demands more than “cute”—it needs believable fur detail, accurate anatomy, expressive eyes, and natural lighting that feels like a real moment with your dog or cat. On Influencer Studio, Flux Ultra 1.1 and Seedream 4.5 both target high-quality results at the same price point, but they excel in different parts of the workflow.
Flux Ultra 1.1 is built for premium, photorealistic image generation with ultra-high detail—ideal when you want a finished, camera-like pet portrait straight from a text prompt. Seedream 4.5 pairs strong generation quality with image-to-image editing, making it a practical choice when you need to iterate on an existing pet photo or refine a generated image into multiple variations.
Pet Photography — Side-by-Side Results
Prompt
"Casual phone-camera portrait at a sunny neighborhood park: a woman in her 20s with shoulder-length wavy brown hair, wearing an oversized hoodie and leggings, crouching at eye level while holding her golden retriever’s leash, glancing near the camera with a natural half-smile like an Instagram story. The dog is centered and adorable with sharp focus on its eyes, ears slightly perked, warm golden-hour lighting, soft background blur of grass and a walking path for a real pet-IG vibe. Shot handheld on a smartphone, natural light only, candid and unposed."

Flux Ultra 1.1 Strengths
- Exceptional fur and whisker detail for close-up dog and cat portraits
- Strong photorealistic lighting and depth for “real camera” pet lifestyle scenes

Seedream 4.5 Strengths
- Image-to-image editing for refining existing pet photos or improving generated outputs

- Efficient for iterative workflows: quick variations on pose, background, or accessories
Verdict
If your priority is a standout, photoreal pet portrait with ultra-fine detail—especially fur texture, eyes, and realistic lighting—Flux Ultra 1.1 is the stronger pick for text-to-image pet photography.
If you expect to revise, remix, or enhance images (for example, adjusting backgrounds, changing styling, or iterating on an existing dog/cat photo), Seedream 4.5 is the more versatile option thanks to its image-to-image editing. Since both cost 16 credits per image, the best choice depends on whether you value maximum “straight-out-of-generation” realism (Flux Ultra 1.1) or editing-driven flexibility (Seedream 4.5).
