Full comparisonCompare Models (select 4)
Seedream 4.5 and Z-Image Turbo are two Influencer Studio image models commonly used for character design—from original characters and game concepts to brand mascots. While both support text-to-image and image-to-image workflows, they’re optimized for different priorities: refinement and edit control versus speed and volume.
This comparison focuses on practical character design needs such as consistent silhouettes, readable costumes, expressive faces, style range (cartoon to semi-real), and iteration speed for exploring variations before locking a final hero design.
Character Design — Side-by-Side Results
Prompt
"Casual phone-camera selfie of an original influencer character (early 20s, warm brown skin with a faint cheek beauty mark, big round glasses, two-tone curly hair—dark roots fading to copper ends) looking slightly off-lens and mid-laugh, wearing an oversized mint hoodie, pleated tennis skirt, and chunky sneakers with a mini crossbody bag. She’s standing in a bright neighborhood café by the pastry case, one hand holding an iced latte and the other angling the phone, natural window light with soft indoor shadows; include clear character-design readability with a strong silhouette, distinctive accessories, and a subtle turnaround-ready stance (feet planted, shoulders angled, hair shape clearly defined). Background feels real and lived-in (menu board, tiled floor, people blurred), candid TikTok/IG story vibe—not editorial."
