# FLUX 3 Klein is here

2026-10-20 · AI Image Studio

Black Forest Labs' fast FLUX 3 image model is now in the image generator, for quick pictures and edits of up to 10 photos.

FLUX 3 Klein, the compact model in Black Forest Labs' new FLUX 3 family, is now in the image generator. Pick it from the model list. It is built to be fast, so it suits jobs where you try many versions and keep one. Every other model stays where it was.

## What you can do with it

- Make a picture from a prompt at 1K, 2K or 4K.
- Upload up to 10 photos and say what to change: a new background, different clothes, new words on a poster, or several photos combined into one scene.
- Choose from nine shapes, from tall 9:21 to wide 21:9. When you edit, Auto keeps the shape of your first photo.
- Write prompts in any language.

In our first tests each image came back in under half a minute, and edits kept the face, pose and layout we asked to keep.

The [FLUX 3 Klein page](https://ai-image.studio/flux-3-klein) shows those test results with their prompts, including the edits and a picture combined from two uploads.
