GPT-Image 1.5 vs Z-Image Turbo
Buildings, facades, and architectural visualization — see how these models compare with real AI-generated outputs.
Full comparisonCompare Models (select 4)
For Architecture & Exterior work—facade studies, building hero shots, streetscapes, and architectural visualization—image models live or die on geometry, material realism, and how reliably they follow design constraints. GPT-Image 1.5 and Z-Image Turbo both generate exterior-focused imagery in Influencer Studio, but they optimize for different priorities.
GPT-Image 1.5 targets high fidelity and strong prompt adherence for detailed, presentation-ready renders. Z-Image Turbo emphasizes ultra-fast iteration, image-to-image workflows, and cost-effective output—useful when you need many variations of massing, style, or facade patterns quickly.
Architecture & Exterior — Side-by-Side Results
Prompt
"Candid smartphone wide-angle selfie of a 20s woman with shoulder-length dark hair in a casual hoodie and black leggings, holding an iced coffee and glancing near the camera while standing on a city sidewalk in front of a striking modern glass-and-concrete building exterior. Dramatic architectural angle with strong leading lines from the façade and pavement converging behind her, golden hour sunlight and long shadows, slightly imperfect framing like an Instagram story. Natural phone-camera look, realistic skin texture, mild motion blur from walking, authentic street background with a few pedestrians and parked bikes."

GPT-Image 1.5 Strengths
- High-fidelity architectural visuals with strong material detail (glass reflections, stone texture, metal panels)
- Strong prompt adherence for design constraints (style, era, massing cues, facade rhythm, lighting direction)
- Handles complex exterior scenes well (streetscapes, landscaping, multiple structures, signage and context)
- Better suited for “final” hero images and client-facing mood renders where realism matters
Z-Image Turbo Strengths
- Ultra-fast generation for rapid exterior ideation and variant exploration (massing, rooflines, fenestration patterns)
- Image-to-image support for evolving an existing facade concept without starting from scratch
- LoRA support for maintaining a consistent architectural style across a series (e.g., specific modernist language or regional vernacular)
- Simple, cost-effective pricing (8 credits per image) for high-volume iteration
Verdict
If your priority is presentation-grade architectural exteriors—clean geometry, believable materials, and tight adherence to a detailed brief—GPT-Image 1.5 is typically the stronger choice, especially at medium/high settings when you need richer facade detail and more coherent scenes.
If you’re iterating quickly on building concepts, producing many facade variations, or need to steer an established look via image-to-image and LoRA, Z-Image Turbo is the practical workhorse. Many teams use Z-Image Turbo for fast exploration, then switch to GPT-Image 1.5 for the final hero renders.
