Full comparisonCompare Models (select 4)
Flux Ultra 1.1 and Reve are two Influencer Studio image models that can help you produce eye-catching, expressive YouTube thumbnail visuals from a simple text prompt. While both support text-to-image generation, they differ in how they handle photoreal detail, stylized aesthetics, and on-thumbnail typography.
This comparison focuses on thumbnail performance: attention-grabbing subjects, clean composition at small sizes, expressive faces and gestures, and the practical need for readable text overlays. We’ll also factor in credit cost per image (Flux Ultra 1.1: 16 credits, Reve: 8 credits) to help you pick the right model for your channel’s workflow.
YouTube Thumbnail — Side-by-Side Results
Prompt
"Close-up YouTube thumbnail-style selfie of a 20s influencer with shoulder-length wavy dark hair, wearing an oversized pastel hoodie and minimal makeup, making an exaggerated shocked expression (wide eyes, mouth slightly open) while holding an iced coffee up to the camera. Candid handheld phone-camera angle in a bright modern café by a window, bold colorful background signage, high-contrast natural daylight with punchy saturation and dynamic composition, looking directly at the lens like an Instagram story screenshot."

Flux Ultra 1.1 Strengths

Verdict
If your YouTube thumbnails depend on premium photorealism—crisp facial detail, cinematic lighting, and realistic textures—Flux Ultra 1.1 is the better fit, especially for creator portraits, dramatic reaction shots, and product-centric visuals where detail sells the story.
If your workflow emphasizes fast iteration, creative styling, and especially accurate in-image typography, Reve is a strong choice for thumbnail concepts that need readable text elements and bold art direction at a lower per-image credit cost. Many creators will use Flux Ultra 1.1 for final “hero” renders and Reve for rapid concept exploration and text-forward variants.
