What is changing?
Black Forest Labs released FLUX 3 Image Klein as open weights on October 15. The 5.6-billion-parameter model supports text-to-image generation, image editing, and multi-reference generation with up to 10 reference images. The company also says it offers native 4K generation and bounding-box controls that define object placement or restrict edits to a selected area.
The release includes a base model for fine-tuning, a low-latency distilled version, and FP8, INT8, and NVFP4 builds developed with NVIDIA support. Diffusers, ComfyUI, and several serving stacks are supported from day one. According to the provider, the weights require 11.2 GB in BF16 and 5.6 GB in FP8, while the INT8 build can run on GeForce RTX systems with 8 GB of VRAM.
The speed and quality results come from company and NVIDIA measurements and should not be treated as independent comparisons. The FLUX Kommunity License allows free commercial use for individuals and companies with annual revenue below $5 million; larger organizations need the API or a separate self-hosted license.
