Dating Profile Photo — Side-by-Side Results
Prompt
"A candid dating-profile style photo of an influencer (mid-20s, shoulder-length wavy brown hair, minimal makeup) wearing a relaxed white tee and light-wash jeans, holding a phone at arm’s length and looking near the camera with a warm, genuine smile. She’s on a sunny city sidewalk outside a cozy café with a latte in her other hand, soft natural daylight and slight street background blur like a real Instagram story selfie. Flattering slightly-above-eye-level angle, casual unposed posture, authentic “just grabbed coffee” vibe."

Flux Ultra 1.1 Strengths
- Exceptional photorealistic detail that supports believable skin texture, hair, and fabric—useful for close-up dating profile shots
- Strong natural lighting and depth that can produce “camera-like” portraits with flattering contrast and crisp facial features
- Premium polish for hero images (primary profile photo) where realism and clarity matter most
- Great for generating clean, high-end lifestyle portraits (coffee shop, city walk, outdoor golden hour) that read as authentic
Seedream 4.5 Strengths
- Image-to-image editing makes it easier to refine an existing photo into a more profile-ready version (adjust vibe, background, outfit styling)
- Versatile style control for dialing in “approachable” looks (soft daylight, casual candid, friendly smile) without over-glossing
- Strong for iterative improvements—swap backgrounds, tweak framing, or nudge expressions while keeping the overall concept consistent
- High-resolution output that works well for cropping into multiple dating-app formats (main photo, secondary shots, prompts)
Verdict
Flux Ultra 1.1 is the better pick when you want a top-tier, photorealistic hero portrait—the kind of crisp, natural-looking main photo that instantly signals quality and confidence. If your goal is maximum realism and premium detail from text prompts, it tends to shine.
Seedream 4.5 is the better pick when you expect to edit and iterate—especially if you’re starting from an existing image and want to refine it into a more attractive, approachable dating profile look. Since both cost 16 credits per image, the best value depends on whether you prioritize premium generation (Flux Ultra 1.1) or flexible editing (Seedream 4.5).
