FLUX 3 Image Klein

A 5.6B-parameter, open-weights member of the FLUX 3 Image family (covered in week 41) that runs on a single consumer GPU, with text-to-image generation, multi-target editing and multi-reference composition from one set of weights. It keeps the family's bounding-box layout control on a 0 to 1000 grid and ships as a distilled checkpoint for fast generation and an undistilled base for fine-tuning and research, with ComfyUI support. Weights are gated on Hugging Face under the FLUX Kommunity License, and product use needs a commercial licence. The repos went up on 13 and 14 October; BFL publishes no benchmarks or Klein-specific pricing.
