MODEL OVERVIEW
Develop manga character sheets and painted scenes with FLUX.3. Start from text or up to ten visual references, then choose 1K, 2K or 4K.
Create with FLUX.3 Klein
Describe the hairstyle, clothing and expression of one original character. Compare the face and silhouette with your design before choosing a variation.
Upload a sharp photo and name both the change and what should stay: for example, replace the background while keeping the product shape and viewpoint. The model can also change unintended details, so compare faces, labels, edges and proportions with the original before using the edit.
Use JPG, PNG or WEBP references of up to 10 MB each. Explain each image's role, such as the subject, setting or colour direction, and avoid contradictory views. Ten is the upload limit, not a guarantee that every identity or detail will be preserved; fewer well-chosen images may make your request clearer.
CORE CAPABILITIES
Develop manga character sheets and painted scenes with FLUX.3. Start from text or up to ten visual references, then choose 1K, 2K or 4K.
Describe the main subject, setting, light and framing before adding style details. For a product concept, specify its material and the space around it. Start with one clear composition rather than several conflicting scenes; you can refine the next attempt after reviewing the first image.

Use 1:1 for square placements, 4:3 or 3:2 for landscape layouts, 3:4 or 2:3 for portraits, and 16:9 or 9:16 for wide or vertical compositions. Auto uses a square for text-only generation and lets an image edit follow its references. Describe where the subject should sit if you need room for later typography.

BEST USE CASES
Anime & Manga
Describe the hairstyle, clothing and expression of one original character. Compare the face and silhouette with your design before choosing a variation.
Build a rain-soaked street or a quiet studio around a readable subject. Keep the light direction and palette consistent with the adjacent panels.
Give each composition one narrative purpose. Review the framing and the position of the subject before assembling it with other panels or shots.
Plan wide or vertical framing for the intended screen. Add exact captions in an editor and review the downloaded file before sharing.

PROMPT EXAMPLES
Anime & Manga
An original manga heroine in a quiet atelier, navy coat, soft window light, clear silhouette, delicate watercolor background.
A fox spirit under a cherry tree at dusk, restrained pink petals, cool shadows, a simple readable composition.
An anime city after rain, reflections on the pavement, one cyclist in the foreground, clean perspective and cinematic framing.
WHAT TO REVIEW
Plan wide or vertical framing for the intended screen. Add exact captions in an editor and review the downloaded file before sharing.
Upload a sharp photo and name both the change and what should stay: for example, replace the background while keeping the product shape and viewpoint. The model can also change unintended details, so compare faces, labels, edges and proportions with the original before using the edit.
Try a tabletop product scene, a seasonal background or a consistent colour direction for a campaign concept. Keep the reference product visible and change one major element at a time. Compare the generated silhouette, packaging and logos with your source; a visually appealing concept is not proof of an exact catalogue match or permission to use a brand.
