Portrait — Side-by-Side Results
Prompt
"Portrait photo of a 20s woman with shoulder-length dark wavy hair in a relaxed hoodie and leggings, holding her phone at arm’s length for a casual selfie while glancing slightly off-camera with a soft, genuine smile. She’s in a sunlit kitchen making iced coffee on the counter, a few everyday items and a messy dish towel in the background, shallow depth of field with warm natural window light and creamy bokeh (85mm lens feel). Keep it candid and approachable like an Instagram story frame, realistic skin texture, minimal makeup, no editorial styling."

Flux Ultra 1.1 Strengths
- Exceptional micro-detail for close-up headshots (skin texture, hair strands, subtle lighting falloff)
- Highly photorealistic portrait rendering suited to premium editorial or beauty-style looks
- Strong perceived depth and material realism in environmental portraits (background bokeh, fabric, accessories)
- Consistent “premium quality” output when the goal is realism over graphic design elements
Nano Banana Pro Strengths
- Industry-leading text rendering for portraits that include typography (titles, taglines, packaging, poster layouts)
- Up to 4K output for high-resolution portrait deliverables and crops without losing clarity
- Multimodal understanding for workflows that reference mixed inputs (useful when steering pose, styling, or scene context)
- Marketing-grade polish for ad-ready portrait compositions and branded creative
Verdict
Choose Flux Ultra 1.1 when your portrait success metric is pure photorealism and fine detail—especially for tight headshots where skin, eyes, and hair realism make or break the image. At 16 credits per image, it’s also the more predictable option for premium-looking portraits on a per-image basis.
Choose Nano Banana Pro when your portraits are part of a designed asset (social ads, thumbnails, covers) that must include clean, readable text, or when you need 4K output. Pricing is resolution-based (22 credits for 1K/2K and 44 credits for 4K), making it a better fit when higher resolution or typography accuracy is the deciding factor.
