Flux Ultra 1.1 vs Grok Imagine
3D renders, CGI scenes, and digital art — see how these models compare with real AI-generated outputs.
Full comparisonCompare Models (select 4)
Flux Ultra 1.1 and Grok Imagine are two Influencer Studio image models that can both produce impressive 3D graphics—ranging from photoreal CGI product shots to stylized digital art scenes. While they overlap on core text-to-image generation, they differ in how they balance realism, creative flexibility, and cost per render.
This comparison focuses on 3D renders and CGI workflows: material realism, lighting behavior, scene coherence, and how reliably each model delivers “render-like” results for environments, characters, and product visualization.
3D Graphics — Side-by-Side Results
Prompt
"Photorealistic 3D render (Blender/Unreal Engine), casual phone-camera selfie of a 22–28-year-old woman with shoulder-length wavy dark hair in a loose hoodie and biker shorts, holding an iced coffee and looking slightly past the lens with a relaxed half-smile. She’s seated at a small window table in a cozy neighborhood café with a pastry plate and laptop stickers visible, candid “work day” vibe, subtle volumetric morning light streaming through the glass and soft subsurface scattering on skin. Realistic PBR materials (ceramic mug, condensation on the cup, worn wood table), shallow depth of field, natural handheld framing like an Instagram story."

Flux Ultra 1.1 Strengths
- Exceptional micro-detail for 3D-like surfaces (metal, plastic, fabric, stone) and crisp edge definition
- Strong photoreal CGI look with convincing lighting, reflections, and high-end “studio render” polish
- Great for premium product-style 3D renders where clean geometry and sharp textures matter
- Reliable at producing high-resolution, portfolio-ready stills with minimal post-processing
Grok Imagine Strengths
- Cost-efficient for iterative 3D concepting and exploring multiple compositions (lower credits per image)
- Image-to-image support for refining existing 3D drafts, paintovers, or render passes into new variants
- Strong creative scene building for stylized CGI, key art, and imaginative digital art environments
- Solid photoreal quality with good detail, especially when you need many options quickly
Verdict
If your priority is premium, photoreal 3D renders—especially product CGI, studio lighting setups, and ultra-crisp material detail—Flux Ultra 1.1 is the stronger pick, albeit at a higher credit cost per image.
If you value speed, iteration, and flexibility for 3D concept art (and you want image-to-image to evolve an existing look), Grok Imagine is the better everyday choice—delivering strong results for a fraction of the per-image credits.
