Image generation and editing models from Black Forest Labs
FLUX is a family of image generation and editing models from Black Forest Labs, a German lab founded by former Stable Diffusion researchers. Some variants have open weights, under Apache 2.0 or a non-commercial license, and can run locally or be fine-tuned. The most capable Pro and Kontext models are offered through a paid API and many partner platforms. Kontext edits existing images from text instructions.
