Architecture & Exterior — Side-by-Side Results
Prompt
"A candid phone-camera selfie of a woman in her mid-20s with long dark hair in a low ponytail, wearing an oversized beige hoodie, black leggings, and white sneakers, holding an iced coffee and glancing near the camera with a relaxed half-smile. She’s on a city sidewalk in front of a striking modern glass-and-concrete building exterior shot at a dramatic upward angle with strong leading lines, reflections in the façade, and a warm golden-hour sky. Natural light, slight handheld motion blur like an Instagram story, everyday street background with a crosswalk and a few pedestrians."

Flux 2 Strengths
- Versatile exterior workflows: strong for iterative concepting with text-to-image plus image-to-image editing
- LoRA support for architectural consistency (e.g., repeating a signature facade language, material palette, or brand style across a series)
- Up to 4MP output for sharper facade textures, signage, and window grids when you need higher-resolution deliverables
- Style transfer for exploring architectural moods (minimalist, brutalist, Mediterranean, neo-futurist) while keeping the same massing
- Face-swap support for lifestyle exterior scenes (e.g., people near entrances/terraces) when marketing compositions require it
Flux Ultra 1.1 Strengths
- Exceptional micro-detail for exteriors: crisp material definition (stone grain, brushed metal, concrete pores) and realistic reflections
- Photorealistic output suited to client-ready hero shots of buildings, streetscapes, and facade close-ups
- Strong lighting realism for golden hour, overcast, night exteriors, and high-contrast glass-and-steel scenes
- Simple premium pipeline: optimized for “generate final render” moments without relying on extra tuning steps
Verdict
If your Architecture & Exterior work involves lots of iteration—adjusting massing, swapping cladding, refining window rhythms, or keeping a consistent design language across a campaign—Flux 2 is the more flexible choice thanks to image editing, style transfer, LoRA support, and up to 4MP output.
If your priority is a smaller number of presentation-grade exterior renders with maximum realism and surface fidelity, Flux Ultra 1.1 is the better fit. Notably, Flux Ultra 1.1 is also priced at 16 credits per image, matching Flux 2’s lower-cost option and undercutting Flux 2’s 22-credit standard tier—making it compelling for final photoreal deliverables.
