Cyberpunk & Sci-Fi — Side-by-Side Results
Prompt
"A 20s woman with shoulder-length teal-dyed hair in a messy half-up clip, wearing a black oversized hoodie, bike shorts, and chunky sneakers, holds her phone at arm’s length for a rainy street selfie, glancing near the camera with a relaxed “just stepped out” expression. She’s under a neon ramen shop awning in a futuristic cyberpunk city, rain-slick pavement reflecting pink/blue/purple signage and holographic ads drifting in the background, with a few commuters in LED jackets passing behind her. Natural phone-camera look with soft streetlight + neon spill, slight motion blur from drizzle, candid UGC vibe (like an Instagram story)."

GPT-Image 1.5 Strengths
- Strong prompt adherence for complex cyberpunk briefs (e.g., specific neon signage colors, camera angles, and mood cues)
- High-fidelity detail in dense scenes like layered skylines, street markets, and rainy alleyways
- Reliable generation of cohesive lighting (neon rim light, volumetric haze, reflections) across the full frame
- Flexible credit tiers (8/16/32) that suit quick explorations through to more premium renders
Seedream 4.5 Strengths
- Powerful image-to-image editing for refining cyberpunk shots (iterate on outfits, props, signage, or environment without restarting)
- High-resolution output that holds up for posters, thumbnails, and wide cityscape compositions
- Versatile style handling—from gritty dystopian realism to sleek, glossy sci‑fi concept art
- Simple per-image pricing (16 credits) that’s easy to budget for edit-driven workflows
Verdict
If your priority is nailing a detailed cyberpunk scene directly from text—especially when the prompt includes many constraints—GPT-Image 1.5 is the stronger starting point. It’s well-suited to generating neon cityscapes with coherent lighting and lots of micro-detail in a single pass, and the tiered pricing makes it easy to choose between fast drafts and higher-effort finals.
If your workflow involves heavy refinement—keeping a base composition while changing armor, tech props, color palettes, or dystopian set dressing—Seedream 4.5 is the better fit thanks to image-to-image editing and consistently high-resolution output. Many creators will use GPT-Image 1.5 for initial concept generation, then switch to Seedream 4.5 to iterate and polish hero frames.
