3D Graphics — Side-by-Side Results
Prompt
"Photorealistic 3D render (Blender/Unreal Engine look) of a mid-20s woman with shoulder-length wavy brown hair wearing an oversized beige hoodie and black bike shorts, holding a phone at arm’s length for a casual front-camera selfie, eyes looking near the lens with a slightly messy “just woke up” expression. She’s in a small sunlit kitchen making iced coffee, one hand stirring a glass on a cluttered counter (oat milk carton, coffee grounds, sticky notes), warm natural window light with soft volumetric rays, subsurface scattering on skin, and realistic physically-based materials on glass/metal surfaces. Authentic UGC vibe like an Instagram story frame—slight motion blur, imperfect framing, and lived-in details, not polished or editorial."

GPT-Image 1.5 Strengths
- Strong prompt adherence for complex 3D scene briefs (camera angle, lighting, composition, props)
- High-fidelity detail that supports “rendered” looks (sharp surfaces, small elements, dense environments)
- Reliable for generating fully new CGI scenes from text without needing a starting image
- Flexible credit tiers (8/16/32) that can match draft-to-final workflows and resolution needs
Seedream 4.5 Strengths
- Best fit for iterative 3D art workflows thanks to image-to-image editing (refine an existing render or concept)
- High-resolution output that holds up for crisp 3D-style presentation and close-up crops
- Versatile style handling—useful for shifting between realistic CGI, toon 3D, and hybrid digital art looks
- Simple per-image pricing (16 credits) for predictable costs when doing consistent edits/variants
Verdict
Choose GPT-Image 1.5 when you need prompt-accurate, high-detail 3D scene generation from scratch—especially for complex CGI compositions where following the brief matters most.
Choose Seedream 4.5 when your 3D workflow depends on editing and refinement—for example, iterating on a base render, adjusting style direction, or polishing a concept through controlled image-to-image changes. For many creators, GPT-Image 1.5 is the stronger “scene generator,” while Seedream 4.5 is the stronger “scene editor.”
