Cyberpunk & Sci-Fi — Side-by-Side Results
Prompt
"A 20s Asian woman with shoulder-length black hair and wispy bangs, wearing an oversized gray hoodie, biker shorts, and chunky sneakers, holds her phone at arm’s length for a casual selfie video while glancing near the camera, mid-laugh, standing under a neon awning on a rain-slick cyberpunk street. Behind her: glowing pink-blue holographic menus, steaming street-food stall, and futuristic scooters passing by with LED signage reflecting in puddles. Natural phone-camera look with soft ambient neon lighting and a little motion blur like a TikTok story clip."

Flux Ultra 1.1 Strengths
- Exceptional micro-detail for cyberpunk environments (signage, cables, rain sheen, reflective pavement) with a premium, photoreal finish
- Strong sense of lighting realism—neon glow, rim light, volumetric haze, and night contrast often look more cinematic and cohesive
- Great for “hero” frames: close-up tech props, character portraits in neon light, and high-impact key art where texture fidelity matters
- Consistent high-end output when you want a grounded, believable near-future look rather than a heavily stylized illustration
Seedream 4.5 Strengths
- Image-to-image editing makes it easier to iterate cyberpunk scenes (swap signage, adjust armor design, change colorways) without restarting from scratch
- Versatile styling for sci-fi: can pivot between gritty dystopia, glossy futurism, anime-leaning neon, and concept-art looks
- Strong for production workflows—refining compositions, maintaining a base scene, and generating variations for campaigns or series posts
- High-resolution output that holds up well for wide neon cityscapes and layered skyline compositions
Verdict
If your goal is premium, photoreal cyberpunk key art—where every raindrop highlight, metal texture, and neon reflection needs to feel “real”—Flux Ultra 1.1 is the stronger pick for final-frame impact at the same 16-credits-per-image cost.
If you anticipate lots of iteration (alternate dystopian billboards, different tech silhouettes, evolving outfits, or consistent series branding), Seedream 4.5’s editing workflow and style flexibility typically deliver faster creative refinement—especially for building multiple variations from a single approved base.
