Black Forest Labs
An AI image generation company known for its Flux series of models, which employ flow matching technology to achieve efficient and low-cost image generation.
Core Facts
Black Forest Labs was founded by members of the original Stable Diffusion team.
Grok's image generation capability is based on the Aurora model, with early versions using the FLUX engine from Black Forest Labs.
Flux is developed by Black Forest Labs and is one of the mainstream diffusion models currently available.
Timeline (last 90 days)
Black Forest Labs released Flux 3 Image in early October, featuring pixel-locked multi-step editing that keeps the remaining pixels bit-for-bit identical when one region is changed.
An independent check of vendor-supplied samples found that the editing feature Flux 3 Image calls pixel-perfect editing produced small pixel shifts in regions that should have remained identical.
On October 15, 2025, Black Forest Labs released the open-weights Flux 3 Image Klein, with 5.6B parameters, which can run on an NVIDIA GPU with 8GB of VRAM after INT8 quantization.
Flux is an image generation model released by Black Forest Labs, and its GGUF quantized versions are often used in ComfyUI to reduce VRAM usage.
FLUX.3 Image Klein is a 5.6B-parameter image model from Black Forest Labs that supports text rendering and image editing with up to 10 reference images, and can run on a GPU with 24 GB of VRAM.
PageRank over the lineage shows that the most depended-upon model on the entire Hugging Face Hub is black-forest-labs/FLUX.1-dev, a non-commercial model.
If Black Forest Labs changed FLUX.1-dev to Apache-2.0, after copying the 43,700-model family with GRAPH.COPY and recomputing, 27,592 models would still retain the non-commercial tag, because their own cards copied FLUX's license and uploaders would need to modify them manually.
FLUX 3 Image offers a 50% discount in its first week of release.
Not all FLUX series models are open source: the team typically distinguishes open weights (locally deployable, with license restrictions) from hosted versions available only via API, and the specific licensing terms vary by model.
Black Forest Labs (BFL) released the FLUX 3 Image image generation model on the social platform X.
