For architecture & exterior work, the difference between a good image and a usable visualization often comes down to facade geometry, material realism, perspective accuracy, and how reliably the model handles signage and wayfinding text. Nano Banana Pro and Seedream 4.5 both produce high-quality building renders in Influencer Studio, but they shine in different parts of an architectural workflow.
This comparison focuses on exterior architectural visualization—buildings, streetscapes, facades, and marketing-style hero renders—looking at output quality, control, editing flexibility, and cost per deliverable resolution.
Architecture & Exterior — Side-by-Side Results
Prompt
"Casual phone-camera selfie of a 20s woman with shoulder-length dark hair in a beige hoodie and black leggings, holding an iced coffee and looking slightly past the lens with a relaxed half-smile while standing on a city sidewalk in front of a striking modern glass-and-concrete building; dramatic low-angle perspective with strong leading lines from the building facade and street curb. Golden hour natural light with warm reflections in the windows, subtle motion blur from passing pedestrians, authentic Instagram story vibe (handheld framing, imperfect crop, everyday candid moment)."

Verdict
Choose Nano Banana Pro when your architecture & exterior output needs to look client-ready—especially if your scene includes readable signage, branded storefronts, or any typography integrated into the facade. It’s also the better fit when you need 4K exports for boards and close-up crops.
Choose Seedream 4.5 when your workflow depends on iterative editing and fast variations from an existing image (image-to-image). For teams exploring multiple facade directions quickly, its editing strength and straightforward per-image cost can make iteration more efficient.
