Krea V3 Edit: edit one photo or combine up to eight
Krea V3 Edit changes a photo from a sentence or merges up to eight references into one image. How to number images in the prompt, Berry or Jam, and seeds.
Most edit models take one picture and one instruction. Krea V3 Edit takes up to eight pictures and lets you point at each one by number in the prompt. That small detail changes what you can ask for. Not only 'make the sky stormy', but 'put the lamp from the second image on the desk in the first, and paint the whole room in the colours of the third'. This guide is about getting that kind of request right the first time.
The one rule: images have numbers
The images you upload are numbered in the order you add them, and the prompt refers to them as <image-1>, <image-2> and so on. The first image is usually the one you are editing, the base the result is built on. Every image after it is a donor: an object, a texture, a style, a colour palette. If the order is wrong, the model may happily paint your living room onto the lamp, so check it before you press Generate.
Write the prompt in two halves. First what changes, naming the donors by number. Then what stays, in plain words: the layout, the people's poses, the camera angle, the light. The examples on the model page do exactly this, and they end with a long 'preserve' sentence for a reason: a model that is told what to keep changes less by accident.
Three edits worth stealing
Replace the plain white mug on the table in <image-1> with the ceramic mug from <image-2>, matching the light direction and the shadow on the table. Keep the hand, the table, the window and the background exactly as they are.Redecorate the room in <image-1> in the style of <image-2>: the wall colour, the wooden floor and the textiles. Add the armchair from <image-3> in the empty corner by the window. Keep the room's walls, windows, ceiling and camera angle unchanged.Turn the paper map on the desk in <image-1> into a raised relief model of the same coastline, with tiny cliffs, turquoise shallows and a small lighthouse, as if carved from painted plaster. Keep the desk, the pencils, the coffee cup and the lighting unchanged.Berry or Jam?
Under the advanced settings there is a choice of two variants. Berry is the default and favours quality; Jam favours speed. A sensible habit: draft the wording on Jam, where a bad prompt costs you less waiting, and switch to Berry for the take you keep. One detail to know: the negative prompt applies to Berry only, so on Jam anything you write there is ignored.
Next to it sits the reasoning level, low by default or medium. Medium spends longer reading the prompt, which helps when the instruction has several parts and several numbered images. For a one-image, one-change edit, low is enough.
Size and format
Leave the size empty and the model picks one on its own, which is what you want when the result should match the base photo. Fill it in as width*height when the result has a fixed home, a banner or a square for a feed; it goes up to about four megapixels. The output is PNG by default, which keeps clean edges for further edits; JPEG is the smaller file for the web. If you are not sure which frame suits the job, the aspect ratio guide helps you choose.
Who should pick it
Pick Krea V3 Edit when the job has more than one source: a product placed into a scene, a room restyled from a mood board, a character put into a new setting with a prop from somewhere else. For a single-picture fix, such as removing a sign or changing the time of day, every edit model on the models page will do, and the edit prompts guide applies to all of them. For combining references with a stronger focus on lettering, compare the Flux 3 multi-image guide.
The honest limitation
Eight images is a ceiling, not a target. Every donor is one more thing the model has to balance, and one more chance that it takes the wrong piece, or blends two references you meant to keep apart. Start with two or three images and add more only when the simple version works. If a donor keeps getting ignored, crop it so the thing you want fills the frame, and name it in the prompt with both its number and a short description, for example 'the green velvet armchair in <image-3>'.
Questions
How many images can Krea V3 Edit take?
One to eight, referred to in the prompt as <image-1>, <image-2> and so on, in the order you upload them.
What is the difference between Berry and Jam?
Berry, the default, favours quality and is the only one that uses the negative prompt. Jam favours speed and is handy for testing the wording.
Can I set the output size?
Yes, as width*height up to about four megapixels. Leave it empty for automatic sizing.
