• Black Forest Labs open-weights FLUX 3 Image Klein, a 5.6B text-to-image and editing model with up to 10 references and bounding-box control

  Black Forest Labs released FLUX 3 Image Klein, a 5.6B-parameter open-weights model for text-to-image, image editing and multi-reference generation with up to 10 reference images, native 4K, pixel-perfect editing and prompt bounding boxes that place or confine edits. The release ships a base checkpoint for fine-tuning and a step-distilled model for low latency, plus FP8, INT8 and NVFP4 builds with NVIDIA, under the FLUX Kommunity License. BFL says Klein ranks first in its open-weights comparisons for text-to-image, multi-reference and editing, runs a 1MP image in about 4 seconds on an RTX 5090 in INT8 via ComfyUI, and is priced from $0.009 per 1K image on the BFL API as flux-3-image-klein. Hugging Face Diffusers added day-one Modular Pipeline support with LoRA training scripts.

API pricing is by resolution and half off until October 8; the company says an open-weights version is weeks away.
