What's New

What's New in Krea 3?

Krea's image editing model: fast 2K edits that leave alone what you didn't mention. Here's what that means on architecture work.

Changes one thing

We gave it a warehouse kitchen and a product shot of a sofa. It swapped the sofa in and kept the floor, the island, the table and the light as they were.

Line drawing to finished room

It follows a detailed brief: Krea's own example turns a hidden-line drawing and a six-colour palette into a finished room, each colour where the brief put it. That's a model export to a material study in one edit.

Reasons before it renders

Krea 3 works out the edit before it draws it, so it takes longer than Flux 3 Klein. We use it for edits that need that care: a reference to place, or one piece to change.

Three quality levels

Medium for quick rounds, High to keep everything outside the edit as it was, Ultra for the most effort on a hard edit.

Workflow

How Do You Use Krea 3?

Upload a view, pick Krea 3 Edit in Edit or Edit Area, say what stays and what changes, then choose the quality and 1K or 2K. Nothing to install.

Step 1

Upload the view

A render, a model export, a line drawing or a photograph. JPG or PNG.

Step 2

Pick Krea 3 Edit

In Edit, or in Edit Area to paint the part to change. Add up to seven reference images alongside the view.

Step 3

Say what stays, then what changes

Name what to keep first, then describe the change the way a photographer would. With several images, say what each one is for.

Step 4

Pick the quality and download

Medium to explore, High to hold the rest of the view, Ultra for a hard edit. 1K or 2K.

Prompts

Which Krea 3 Prompts Work for Architecture?

Start with what stays, then the change, then what each image is for. Use only when the edit should touch one thing. Three edits and the exact prompt behind each.

01Edit

Line drawing and a palette to a finished room

Keep the room, the camera and every line of the drawing exactly as they are. Turn image 1 into one photorealistic architectural photograph in soft morning light. Take every material from the palette in image 2: A on the kitchen island, B on the roof trusses and the table, C on the window frames, D on the floor, E on the walls, F on the taps and the pendant lamps.

02Edit

Replace only the sofa

Keep the room, the light and everything else exactly as it is. Replace only the sofa by the window in image 1 with the sofa from image 2, at the same size and position.

03Edit Area

One material, painted in

Keep everything outside the painted area as it is. Change only the floor to wide reclaimed oak boards with a matte oil finish.

Krea 3 FAQs

What you'll want to know before putting Krea 3 on a client job.

Krea 3 is Krea's image editing model, released on 15 October 2026. It changes the part of an image you ask for and keeps products, people and text intact elsewhere, generating natively at 2K. In Fenestra it's Krea 3 Edit, in Edit and Edit Area.
Krea 3 is built to edit an existing image; Krea 2 is Krea's earlier image generator, known for its eye for style. Krea says Krea 3 keeps that eye for style, so paintings, ink drawings and vector art stay in their own medium when you edit them. Fenestra has Krea 3 Edit.
Use Krea 3 Edit for edits to an existing view that follow a detailed brief, like a line drawing and a material palette, with Medium, High or Ultra quality at 1K or 2K. Use Flux 3 Klein to create from text, for Regional Edit boxes, for 4K, or for quick low-cost rounds. Both are in Fenestra, so run the same edit through each and keep the better one.
It's included on every Fenestra plan and uses credits like our other models. The cost depends on the quality level, the resolution and how many images you send, and the exact figure is on the generate button before you run it.
Yes. Everything you generate on a paid plan comes with full commercial rights, covering client presentations, competition submissions, your website and social channels.
Open a project, choose Edit or Edit Area, and pick Krea 3 Edit. Start the prompt with what should stay, then describe the change, and say what each reference image is for, such as image 1 is the room, image 2 is the sofa. Use only when the edit should touch one thing. Then pick Medium, High or Ultra and 1K or 2K.
There's no independent comparison yet. Krea built Krea 3 for edits that change one thing and keep the rest, and that's where we'd use it: placing a product from a reference into an existing view. For anything else, run the same edit through Nano Banana Pro from the model picker and keep the better one.
Medium for quick rounds. High when everything outside the edit has to stay exactly as it was; on a single image it keeps those pixels in place. Ultra spends the most effort on a hard edit and always renders at 2K. Higher levels take longer and use more credits.
A JPG or PNG view as the base image, plus up to seven more images as references: product shots, material samples, palettes, photographs or a mood board. Refer to them by number in the prompt.
