Full comparisonCompare Models (select 4)
Flux Ultra 1.1 and GPT-Image 1.5 are two strong options in Influencer Studio for creating game and film concept art—especially environment design, keyframes, and mood-driven scene exploration. Both handle text-to-image well, but they differ in how they trade off photoreal finish, controllability, and iteration cost.
If your workflow involves rapid worldbuilding passes, readable silhouettes, and consistent prompt intent, you’ll likely notice GPT-Image 1.5’s adherence and flexibility. If you need premium, high-impact frames with exceptional micro-detail and a more photographic finish, Flux Ultra 1.1 is built to deliver that “final key art” look.
Concept Art — Side-by-Side Results
Prompt
"A 20s woman with shoulder-length wavy dark hair in a loose hoodie and biker shorts holds her phone slightly above eye level for a casual front-camera selfie, mid-laugh while glancing near the lens, one hand wrapped around an iced coffee. She’s in a bright neighborhood café by a window with street reflections, messy tote bag and earbuds on the table, natural morning light and subtle motion blur for a real Instagram story feel. Render as AAA game/film concept art pre-production: painterly brushstrokes, dramatic but believable composition, environmental storytelling and matte-painting quality while keeping it authentically candid and unpolished."
