Cyberpunk & Sci-Fi — Side-by-Side Results
Prompt
"A candid phone selfie of a 20s woman with shoulder-length black hair and subtle neon-pink streaks, wearing an oversized gray hoodie, bike shorts, and chunky sneakers, looking slightly past the camera while holding a takeaway coffee and adjusting her hood. She’s standing under a glowing ramen-shop awning on a rain-slick cyberpunk street with blue/purple/pink neon reflections, holographic ads drifting above the sidewalk, and a few futuristic scooters behind her. Natural rainy-night street lighting with phone-camera flash fill, casual TikTok/IG-story vibe with slight motion blur like she just started recording."

Flux 2 Strengths
- LoRA support for consistent cyberpunk styling (e.g., a repeatable “neon-noir” look across a series)
- Versatile image-to-image editing for iterating on city density, signage, haze, and lighting without restarting from scratch
- Up to 4MP output for sharper architecture lines, holographic UI details, and readable signage elements
- Style transfer options that help push distinct dystopian aesthetics (gritty, retro-future, neon-gloss) from reference images
- Face-swap support for maintaining a consistent protagonist/creator persona in sci-fi scenes
Seedream 4.5 Strengths
- Strong editing capabilities for fast refinements to mood, lighting, and composition in neon-heavy scenes
- High-quality output that suits polished sci-fi key art and clean futuristic tech renders
- Versatile styles for switching between glossy “future lab” aesthetics and gritty dystopian street looks
- Straightforward pricing at 16 credits per image, useful for frequent iteration and batch generation
Verdict
Choose Flux 2 when you need maximum control and repeatability for cyberpunk series work—especially if consistent styling via LoRA, higher-detail 4MP exports, or character continuity (via face-swap) are important to your workflow. It’s a strong fit for creators building a recognizable neon-dystopian “signature look” across many posts.
Choose Seedream 4.5 when you want high-quality sci-fi and cyberpunk outputs with strong editing and an efficient per-image cost. It’s a practical option for rapid concept exploration—trying multiple neon palettes, tech designs, and scene variations without credit overhead.
