Architecture & Exterior — Side-by-Side Results
Prompt
"Handheld phone photo (vertical 9:16) of a woman in her mid‑20s with wavy dark-brown hair, wearing an oversized beige trench coat, white tee, and sneakers, standing on a city sidewalk and casually glancing near the camera while holding an iced coffee. Behind her is a striking modern glass-and-concrete building exterior shot from a dramatic low angle with strong leading lines and reflections, golden hour sunlight hitting the façade and a soft warm sky. Candid influencer vibe like an Instagram story—slightly imperfect framing, natural street lighting, a bit of motion blur from walking."

- Reliable for complex, multi-element scenes (building + context + lighting + camera angle) without losing the brief
- Flexible quality tiers (8/16/32 credits) to match iteration speed vs final-render needs
Seedream 4.5 Strengths
- Image-to-image editing for exterior iterations (facade swaps, material changes, signage/streetscape tweaks) while preserving the base composition
- High-resolution output well-suited for presentation boards and close-up facade crops
- Versatile architectural styles (modern, brutalist, vernacular, neo-classical, conceptual) with strong aesthetic range
- Simple per-image pricing (16 credits) that’s easy to predict for standard deliverables
Verdict
Choose GPT-Image 1.5 when you need dependable prompt control and high-fidelity exterior scenes from scratch—especially for early concept generation where accurate adherence to constraints (style, materials, camera, context) matters.
