Looking to generate polished anime-style characters, crisp manga linework, or clean cel-shaded scenes in Influencer Studio? Flux Ultra 1.1 and Seedream 4.5 both deliver high-quality results at the same price point, but they excel in different parts of an anime workflow.
Flux Ultra 1.1 leans into ultra-fine detail and premium rendering, which can translate into richly textured anime illustrations (and anime-adjacent “semi-real” looks). Seedream 4.5 stands out for versatility—especially when you want to iterate, refine, or transform an existing image while keeping an anime aesthetic consistent.
Anime — Side-by-Side Results
Prompt
"Anime-style cel-shaded illustration of a 20s woman with shoulder-length teal hair and soft bangs, big expressive eyes, wearing an oversized beige hoodie and black biker shorts, holding her phone up for a mirror selfie while glancing slightly toward the camera with a relaxed half-smile. She’s in a small apartment bedroom doing a casual “outfit check,” messy bed and laundry basket in the background, warm morning window light and subtle phone flash reflection for a real Instagram Story vibe. Natural, imperfect framing with a little motion blur in her hand like a candid TikTok thumbnail."

Seedream 4.5 Strengths
- Image-to-image editing for refining faces, outfits, poses, and backgrounds without restarting from scratch

Verdict
Choose Flux Ultra 1.1 when your goal is premium, ultra-detailed anime key art—especially “high polish” renders with dramatic lighting, intricate costumes, and sharp finish. It’s a strong pick for hero images where the final frame matters more than rapid iteration.
Choose Seedream 4.5 when you want an anime model that supports an editing-driven workflow—iterating on an existing image, keeping character identity stable across variations, and dialing in cel-shading or manga aesthetics through controlled revisions. With both priced at 16 credits per image, the best value depends on whether you prioritize maximum detail (Flux Ultra 1.1) or flexible refinement (Seedream 4.5).
