Full comparisonCompare Models (select 4)
Concept art for games and film demands two things at once: strong visual storytelling (mood, composition, readable silhouettes) and rapid iteration (variations, lighting passes, and environment explorations). In Influencer Studio, GPT-Image 1.5 and Z-Image Turbo approach that balance differently.
GPT-Image 1.5 emphasizes high-fidelity renders and reliable prompt adherence for detailed scenes, while Z-Image Turbo is built for ultra-fast, cost-effective generation and supports image-to-image workflows plus LoRA styles—useful when you need many passes quickly or want to lock into a specific art direction.
Concept Art — Side-by-Side Results
Prompt
"Concept art, AAA game pre-production style with painterly brushstrokes and matte-painting realism: a 20s woman with shoulder-length wavy dark hair in a cozy oversized hoodie and black leggings, holding her phone slightly above eye level for a casual selfie video, glancing toward the camera with a relaxed half-smile like a TikTok “morning coffee check-in.” She’s seated by a rainy café window with a latte and open laptop on a small table, street reflections and passing umbrellas outside adding environmental storytelling; natural overcast window light, subtle motion blur from her hand, candid unpolished vibe."
