Portrait — Side-by-Side Results
Prompt
"Portrait photo of a 20s woman with shoulder-length wavy dark brown hair, minimal makeup, wearing an oversized gray hoodie and leggings, holding her phone slightly above eye level for a casual front-camera selfie while glancing near the lens with a relaxed half-smile. She’s in a cozy kitchen making iced coffee on the counter (mug, oat milk, a little clutter), soft natural morning window light, shallow depth of field with warm bokeh in the background, 85mm lens feel emphasizing her face and candid expression."

Flux Ultra 1.1 Strengths
- Exceptional facial detail for close-up headshots (skin texture, eyelashes, hair strands) with a premium photorealistic finish
- Stronger realism in lighting and depth-of-field for “camera-like” portraits, including convincing background separation
- More consistent anatomy and facial proportions in single-image portrait generations
- Great for high-end editorial, beauty, and lifestyle portraits where small artifacts are unacceptable
Z-Image Turbo Strengths
- Faster portrait iteration for exploring poses, outfits, and locations quickly—useful for concepting and mood boards
- Lower per-image cost (8 credits) for high-volume portrait testing and batch generation
- Image-to-image support for refining an existing headshot or re-styling an environmental portrait while keeping composition
- LoRA support for stronger style or character steering (e.g., consistent “brand face,” makeup style, or wardrobe aesthetic)
Verdict
Flux Ultra 1.1 is the better pick when your portrait needs to look premium and photographic—especially for tight headshots where viewers notice eye detail, skin rendering, and subtle lighting. At 16 credits per image, it’s best used for final selects and hero assets.
Z-Image Turbo is ideal when speed, budget, and control matter most. With image-to-image and LoRA support at 8 credits per image, it’s a strong choice for rapid portrait exploration, consistent styling workflows, and iterative refinement—then you can reserve premium generations for the final deliverables.
