Full comparisonCompare Models (select 4)
Designing original characters, game characters, and mascots demands more than a nice render: you need reliable prompt adherence, controllable style, readable silhouettes, and consistent details like outfits, colors, and signature props. On Influencer Studio, GPT-Image 1.5 and Z-Image Turbo both generate character art from text, but they excel in different parts of the workflow.
GPT-Image 1.5 focuses on high-fidelity output and strong prompt-following for detailed character scenes and polished hero shots. Z-Image Turbo prioritizes speed and cost-effective iteration, adding image-to-image and LoRA support to help you refine a character direction quickly or align with a specific aesthetic.
Character Design — Side-by-Side Results
Prompt
"A candid phone-camera selfie of an original influencer character (mid‑20s, warm medium-brown skin, freckles across the nose, big round glasses, asymmetrical curly bob with one side shaved and a dyed teal streak) looking slightly off-camera while holding an iced coffee, wearing an oversized cream hoodie layered under a rust-orange utility vest, pleated tennis skirt, and chunky sneakers with mismatched socks. Real café setting by a window with natural morning light, messy tote bag and stickers-covered laptop on the table; pose is relaxed and mid-laugh, but with clear character-design silhouette and outfit details like enamel pins, keychain lanyard, and patterned phone case. Keep it authentic like an Instagram story still (subtle noise, imperfect framing, casual background clutter), not cinematic or editorial."
