Black Forest Labs opens FLUX 3 Image Klein: 5.6B text-to-image and editing model that runs in 8GB VRAM
As of Oct 15, FLUX 3 Image Klein ships as open weights (base for LoRA fine-tuning plus a step-distilled model) with native 4K output, bounding-box edits, and up to 10 reference images; the INT8 build runs on 8GB RTX GPUs via ComfyUI or Diffusers. It's under the FLUX Kommunity License (free commercial use under $5M revenue) and on the BFL API as flux-3-image-klein from $0.009 per image.
