Creating standout anime visuals in Influencer Studio often comes down to two things: how precisely a model follows your character brief (hair, outfit, pose, expression) and how well it renders the anime look—clean linework, cel-shaded lighting, and manga-friendly composition.
This comparison looks at GPT-Image 1.5 and Seedream 4.5 specifically for anime-style characters, manga aesthetics, and cel-shading. We’ll cover prompt adherence, consistency, scene detail, and when editing workflows matter most—along with how their credit costs typically play out.

Prompt
"Anime-style cel-shaded illustration of a 20s woman with shoulder-length vibrant teal hair and large expressive eyes, wearing an oversized beige hoodie and black biker shorts, holding her phone slightly above eye level for a casual selfie while glancing near the camera with a relaxed half-smile. She’s in a cozy neighborhood café by a window with soft morning natural light, iced latte and pastry on the table, a tote bag on the chair, and subtle story-caption vibes like a “day in my life” Instagram clip. Keep it candid and imperfect (slight motion blur, messy table crumbs), like a real TikTok thumbnail shot on a phone camera."
