FLUX.3 Image Klein is a model you can download and run yourself. It makes images from a written description and edits them with reference images, holds a character or subject steady across a set of pictures, borrows a style from a reference and draws legible text. Within the FLUX.3 Image line it is the smaller, quicker model.

FLUX.3 Video makes video with matching sound from a written description, an image used as the opening and closing frame, or an existing clip you want to continue. Clips run 5 to 20 seconds, from HD up to 4K, in shapes up to 21:9. It suits controlled scenes, bringing a still picture to life and extending footage.

Send a clip and a written instruction to FLUX Video Edit and get the same clip changed: objects or characters added, removed or swapped, a new setting, rewritten on-screen text, new colors or materials, or translated speech with matching lip sync. Length, shape and soundtrack stay as filmed. The clip must be shorter than 15 seconds and under about 50 MB, and anything sharper than HD is reduced to HD.

FLUX Video Upscale takes one finished video and enlarges it 1.5 to 3 times, leaving the length unchanged, with an optional written instruction to guide the result. Choose the precise mode to stay faithful to the original, or the creative mode to let the model add detail. Use it to sharpen footage for a bigger screen. It creates nothing new: for fresh clips use FLUX.3 Video, and to change what happens in a clip, FLUX Video Edit.
