Black Forest Labs releases FLUX.2 [klein] compact image models

Black Forest Labs has released FLUX.2 [klein], a family of compact image models, reported to come in 4B and 9B sizes and built for fast, near-real-time generation on consumer hardware. It is positioned as the openly licensed member of the new FLUX.2 generation.
What was released
FLUX.2 [klein] follows the FLUX.1 family, whose schnell version is Apache 2.0 and whose dev version is non-commercial. Positioning klein as the open, commercially usable option repeats that split at the new generation. The smaller 4B model targets speed on modest VRAM, with a larger 9B for more headroom. Image-quality and speed claims are the developer’s own until independent comparisons appear, and it is worth confirming the exact licence terms on the model card before building on it commercially.
Why it matters
The licence is the practical headline. As we cover in local image generation, FLUX.1 [dev]‘s non-commercial terms are a common trap for people who want to use generated images in their work. A capable, current FLUX model released openly gives commercial users a clearer option, alongside SDXL and Qwen-Image.
The context
Local image generation has settled into a few families: the SDXL ecosystem for customisation, FLUX for quality and text rendering, and newer permissive entrants like Qwen-Image. A new FLUX generation with an openly licensed, compact member keeps the fast-moving part of that landscape accessible to people running on their own GPUs, usually through a tool like ComfyUI.
We will add a FLUX.2 [klein] entry to the catalogue once its sizes, memory requirements, and licence are confirmed against the model card.
