Full comparisonCompare Models (select 4)
Choosing the right image model for anime-style characters and manga aesthetics comes down to two things: how well the model locks onto your prompt (style, outfit, pose, mood) and how cleanly it renders cel-shading, linework, and facial features without drifting into semi-realistic artifacts.
Below is a practical comparison of Flux Ultra 1.1 and GPT-Image 1.5 in Influencer Studio, specifically for anime workflows—character sheets, key art, dynamic action frames, and panel-like compositions—along with what you get for the credits.
Anime — Side-by-Side Results
Prompt
"Anime-style cel-shaded illustration of a 20s woman with shoulder-length teal hair and big expressive eyes, wearing an oversized gray hoodie and biker shorts, holding her phone up for a slightly messy mirror selfie while looking just off-camera with a shy half-smile. She’s in a small apartment bedroom doing a “GRWM” moment—unmade bed, laundry basket, skincare bottles on the dresser, soft morning window light and a tiny bit of phone flash glare for that real Instagram story feel. Candid, approachable vibe with subtle motion like she just adjusted her hoodie drawstrings mid-shot."

Flux Ultra 1.1 Strengths
- Excels at ultra-crisp detail that can elevate anime key art (hair strands, fabric texture, accessories) when you want a premium finish
- Strong for polished, poster-like compositions where you want a “high-end render” look with clean edges and depth
- Great when you need consistent high quality per output (single pricing tier at 16 credits per image makes budgeting straightforward)
- Useful for anime images that intentionally blend cel-shading with more realistic lighting and material definition
GPT-Image 1.5 Strengths
- Strong prompt adherence for anime specifics (character traits, outfit elements, color palettes, camera angles, and scene requirements)
- Versatile output across anime looks—from softer manga tones to sharper cel-shaded styles—depending on how you prompt
- Flexible pricing tiers (8/16/32 credits) let you iterate cheaply on concepts and then upscale quality for finals
- Handles detailed scenes well for anime environments (streetscapes, classrooms, fantasy interiors) while keeping the prompt’s structure intact
Verdict
Pick Flux Ultra 1.1 when your priority is premium, ultra-detailed anime key art—especially if you like a slightly more “rendered” finish with rich lighting and crisp micro-details. At 16 credits per image, it’s a reliable choice for final outputs where you want maximum polish per generation.
Pick GPT-Image 1.5 when control and iteration matter most for anime production: tight prompt adherence, dependable scene compliance, and the ability to draft at 8 credits before committing to higher-fidelity passes. It’s often the better fit for building a character design through multiple revisions, then producing finals at medium or high.
