Black Forest Labs releases 5.6B-parameter FLUX 3 Image Klein model

black forest labs has released flux 3 image klein, a 5.6 billion parameter open-weights model for text-to-image generation, image editing, and generation with up to ten reference images. it supports native 4k output, pixel-accurate editing, and bounding boxes for element placement. the model scores the highest elo ratings among all open models in internal testing, beating closed competitors ideogram v4.5 and even bfl's own flux.2 [pro] by 91 elo points, with 38 percent fewer parameters than that model's 9 billion. an int8 build lets it run on nvidia gpus with just 8 gb of vram, generating an image in under 9 seconds on an rtx 4070.
