About FLUX.2 [klein] 4B
FLUX.2 klein 4B is a distilled image-generation and multi-reference editing model developed by Black Forest Labs. The official checkpoint has 4 billion parameters and is released under Apache 2.0. Its model card reports approximately 13GB VRAM for local use; requirements depend on the runtime and configuration. It supports text-to-image and image-to-image workflows. Generated text may be distorted, and outputs can miss the prompt or reflect biases. This record refers to black-forest-labs/FLUX.2-klein-4B, not the base checkpoint or klein 9B.
