About

FLUX 3 Image Klein is a 5.6B-parameter image model from Black Forest Labs. A single set of weights handles instruction-based image editing, text-to-image generation, and composition from up to ten reference images. It also supports layout control with bounding boxes, where each element gets a box and a description on a 0–1000 grid.

BFL releases an undistilled version for fine-tuning and research and a distilled version for fast editing and generation. The model is designed to run on a single consumer GPU. Output up to 4K is available through the BFL API. It is meant to be used with a prompt upsampler, which is included automatically in the API and available separately for self-hosted use.

Weights and the prompt upsampler are downloaded from Hugging Face and can be run in ComfyUI or a custom pipeline. They are released under the license on the Hugging Face model card. BFL states that running Klein in a product requires a commercial license for self-hosted deployment at scale. One YouTube reviewer described the license as non-commercial community and reported weak faces and anatomy in his tests.
