Flux 3 Klein creator guide
Use Flux 3 Klein when these strengths match the brief before spending credits.
From 2 credits at 1K and 7 credits at 4K, the same price for text-to-image and editing.
Guide an edit with up to 10 JPEG, PNG or WebP images in one request.
Move from a 1K draft to a 4K render with the same model and prompt.
Generate square, landscape, portrait, panoramic and tall formats directly, with Auto for edits.
Use Flux 3 Klein on AISnapEdit when you want many quick image drafts or edits at a low credit cost, with 4K available for the final version.
At 2 credits per 1K image, Flux 3 Klein suits briefs where you expect to try several prompts, ratios or references before choosing one.
Use image to image to change one element of a photo, such as a color, a background or an object, while asking the model to keep everything else.
Up to 10 references let you supply a product, a person, a material and a style board in the same edit.
Keep drafts at 1K or 2K, then render the chosen direction at 4K without switching models.
Use these Flux 3 Klein prompt ideas for text to image drafts and reference-based edits.
Replace the background with [new setting], keep the subject, pose, clothing and lighting direction unchanged, realistic shadows on the ground.
Short prompts are fine for text to image
Text-to-image prompts are expanded into a fuller description before generation, so a short idea can still produce a detailed image. Add specifics only where they matter to you.
Write edits as precise instructions
Edits use your instruction as written. Say what to change and what must stay the same, for example pose, lighting, background or text.
Give each reference a role
With several references, say which image supplies the product, which the setting and which the style, for example "the product from image 1".
Use Auto to keep the source framing
When editing, Auto keeps the aspect ratio of the first reference image. Pick a fixed ratio only when the result needs a new format.
These Flux 3 Klein examples show how to brief a text-to-image draft, a single-change edit and a multi-reference composite.
Use this when you need a quick, mood-driven image for a social post or blog header.
A corgi wearing a yellow rain hat sitting on wet stone steps after the rain, soft overcast light, reflections on the stones, shallow depth of field, calm and cozy mood.
Expected output: A single character image with a clear subject, wet-surface reflections and a soft background, ready to compare against other drafts.
Use Flux 3 Klein image to image when a product photo is right except for one detail.
Change the backpack to dark green and keep everything else unchanged: same pose, lighting, background and camera angle.
Expected output: The same photo with the backpack recolored, while the composition and lighting stay close to the original.
Use this when a product, a location and a style reference should come together in one campaign image.
Place the product from image 1 on the cafe table from image 2, match the warm film look of image 3, natural window light, realistic shadows, premium lifestyle photography, no text.
Expected output: A lifestyle composite that combines the product, the setting and the color treatment of the references.
