Why FLUX 3 Image Klein is worth a try
Short prompts, full scenes
Klein is trained on long scene descriptions, so Pixel Dojo expands your short prompt into one before it renders. One line about a ramen bowl comes back with the steam, the wood grain and the light worked out.
Words that read
Put the words in quotes and say where they go. On our festival poster, NIGHT ORCHARD fills the top and the date line sits at the bottom, both spelled exactly as typed.
Edits from up to 10 references
Attach reference images and the prompt becomes an instruction. Keep a product and move it to a new scene, restyle a room, or combine people and objects from several photos.
1K or 2K, seven frames
Pick about 1 or 4 megapixels and 1:1, 4:3, 3:4, 3:2, 2:3, 16:9 or 9:16. With a reference, Auto keeps the shape of your first image.
Unlimited on Relax
Every plan can run FLUX 3 Image Klein in Relax, a slower queue that uses no credits. Pick Relax next to Generate when you are not in a hurry.
FLUX 3 Image Klein vs FLUX 3 Image on a festival poster
We sent the same poster prompt to both models at 2K in a 2:3 frame. FLUX 3 Image Klein answered with huge stacked amber letters over a glowing moon and rounded fruit trees. FLUX 3 Image drew a detailed full moon above a long orchard row in a cream and plum palette. Both set every word as written. Klein made its poster for 1 credit, FLUX 3 Image for 1.5.
Same prompt: Screen print festival poster, bold stacked letters "NIGHT ORCHARD" across the top, a giant pale moon over rows of glowing fruit trees, deep plum and amber palette, small text at the bottom reading "SEPT 20, VALLEY STAGE"

Edit a product shot with one sentence
We gave FLUX 3 Image Klein our coffee dripper photo from the showcase as a reference and asked for the same product on a snowy cabin windowsill at dawn.
One reference image and one sentence: the dripper, stand and carafe kept, the scene moved to a frosty cabin window at dawn.
Put the coffee dripper and carafe from image 1 on a snowy cabin windowsill at dawn, frost on the glass, keep the product exactly as it is
- Name what to keep. "Keep the product exactly as it is" held the dripper, the walnut stand and the carafe while the whole scene changed around them.
- With a reference and Auto, the new image keeps the shape of the photo you attached, so a 4:3 product shot stays 4:3.
