GPT-Image 1.5 vs Z-Image Turbo
Hyperrealistic renders indistinguishable from photographs — see how these models compare with real AI-generated outputs.
Full comparisonCompare Models (select 4)
When your goal is true photorealism—images that read as real camera captures—small differences in detail, lighting behavior, and prompt accuracy matter. GPT-Image 1.5 and Z-Image Turbo both generate realistic imagery in Influencer Studio, but they’re optimized for different priorities.
This comparison focuses specifically on hyperrealistic results: believable skin texture, natural depth of field, accurate materials (glass/metal/fabric), clean edges, and consistent scene logic. We’ll also factor in workflow fit (speed, iteration, and controls) and how pricing affects high-volume photorealistic production.
Photorealistic — Side-by-Side Results
Prompt
"Hyperrealistic DSLR-quality photo of a 22–28-year-old woman with shoulder-length wavy brown hair and light freckles, wearing an oversized gray hoodie and black leggings, holding her phone slightly above eye level for a casual front-camera selfie while glancing near the lens with a relaxed half-smile. She’s sitting at a small café window table with an iced latte, messy bun hair tie on her wrist, and a tote bag on the chair, with soft natural daylight spilling in and gentle reflections on the glass. The scene feels like an Instagram story “quick coffee run” moment—slight motion blur in the background, natural skin texture and imperfections, true-to-life colors and lighting."

GPT-Image 1.5 Strengths
- High-fidelity photorealism with strong micro-detail (skin, hair, fabric weave, reflections)
- Strong prompt adherence for precise camera, lighting, and composition instructions
- Handles complex, detailed scenes with better coherence (objects, backgrounds, and lighting consistency)
- Versatile output quality options (low/medium/high) to balance realism vs cost per render
Z-Image Turbo Strengths
- Ultra-fast generation for rapid photorealistic iteration and concept exploration
- Cost-effective, predictable pricing (8 credits per image) for high-volume testing
- Image-to-image support for refining an existing realistic frame (pose, lighting, styling tweaks)
- LoRA support to steer toward a specific photorealistic look (brand style, wardrobe, product aesthetic)
Verdict
Choose GPT-Image 1.5 when photorealism is the primary KPI and you need the most convincing “shot on a camera” finish—especially for close-ups, premium product realism, and scenes where lighting/material accuracy must hold up under scrutiny. Its stronger prompt adherence also helps when you’re directing specific lens, exposure, and staging details.
Choose Z-Image Turbo when speed and iteration volume matter most, or when you want to leverage image-to-image and LoRA workflows to converge on a realistic look quickly. It’s a strong fit for fast pipelines, consistent budgeting, and guided photorealism where you’re refining from a starting image rather than generating perfection in one pass.
