GPT-Image 1.5 vs Z-Image Turbo
3D renders, CGI scenes, and digital art — see how these models compare with real AI-generated outputs.
Full comparisonCompare Models (select 4)
Influencer Studio offers two strong options for 3D Graphics creation: GPT-Image 1.5 for high-fidelity, prompt-accurate CGI imagery, and Z-Image Turbo for rapid, cost-effective generation with flexible style tuning. If your work includes 3D renders, cinematic CGI scenes, or polished digital art, the right choice depends on whether you prioritize detail and control or speed and iteration.
This comparison focuses on practical 3D outcomes—materials and lighting realism, geometry-like consistency, scene complexity, and how well each model supports common workflows like concept exploration, look-dev, and stylized “3D illustration” art.
3D Graphics — Side-by-Side Results
Prompt
"Photorealistic 3D render (Blender/Unreal Engine look) of a 20s woman with shoulder-length wavy dark hair in a cozy oversized hoodie and biker shorts, holding her phone at arm’s length for a casual front-camera selfie, eyes looking just past the lens like she’s mid-sentence for an Instagram Story. She’s standing in a small sunlit kitchen next to a messy countertop with a half-made iced coffee and grocery bags, soft natural window light with subtle volumetric rays, realistic skin subsurface scattering and physically-based materials (ceramic mug, stainless fridge, wrinkled fabric). Slight handheld framing, candid expression, everyday clutter, authentic UGC vibe (not editorial, not cinematic)."

GPT-Image 1.5 Strengths
- Higher-fidelity 3D look: sharper surfaces, cleaner edges, and more convincing material detail (metal, glass, skin, plastics)
- Strong prompt adherence for complex CGI direction (camera angle, lens feel, lighting setups, environment cues)
- Handles dense, detailed scenes well (multi-object compositions, layered props, intricate set dressing)
- Better for “final-frame” renders where polish matters more than rapid iteration
- Flexible output style range—from photoreal CGI to stylized 3D digital art—without losing structural clarity
Z-Image Turbo Strengths
- Ultra-fast generation for rapid 3D concept iteration (blocking scenes, trying lighting variants, exploring silhouettes)
- Cost-effective at a flat 8 credits per image, making it easier to run many variations
- Image-to-image support for refining an existing 3D concept, adjusting composition, or pushing a render toward a new look
- LoRA support for consistent 3D aesthetics (specific character style, studio look, product-render vibe) across batches
- Great for early look-dev, mood boards, and style exploration where speed and volume matter
Verdict
Choose GPT-Image 1.5 when your 3D Graphics need high-end fidelity—cleaner detail, stronger prompt control, and more reliable results for complex CGI scenes that read like finished renders.
Choose Z-Image Turbo when you want to iterate quickly and cheaply, especially if you rely on image-to-image and LoRA workflows to lock in a consistent 3D style or evolve an existing concept. Many creators use Turbo for exploration and GPT-Image 1.5 for the final polished frames.
