About

FLUX.2 [klein] 9B is a member of Black Forest Labs' FLUX.2 [klein] family, described by the vendor as its fastest models. It is a step-distilled, guidance-distilled model (4-step inference) that handles text-to-image generation, single-reference editing and multi-reference editing in one model. It is aimed at real-time and interactive applications.

The weights are published on Hugging Face and run through the diffusers Flux2KleinPipeline. The 9B variants use the FLUX Non-Commercial License, unlike the 4B variants, which are Apache 2.0. Commercial use of the 9B weights therefore needs a separate license from Black Forest Labs. Related variants include 9B KV, which uses KV caching and is faster for multi-reference editing, and 9B Base (50-step), intended for fine-tuning and LoRA training.

It is also available through the Black Forest Labs API on a pay-as-you-go basis, and in the vendor's playground. A YouTube creator reported that in-painting through a third-party app failed with a rejected endpoint URL error when using a Flux model. That points to an integration issue and is not a documented limitation of the model.
