Black Forest Labs ships FLUX 3 Image Klein as open weights
Black Forest Labs
On October 15, 2026 Black Forest Labs released FLUX 3 Image Klein, a 5.6B-parameter open-weights model under the FLUX Kommunity License (free commercial use under $5M revenue). It supports text-to-image, image editing, and multi-reference generation with up to 10 reference images, native 4K output, and leads BFL's blind evaluations among open models; API pricing starts at $0.009 per 1K images and INT8 builds run on 8 GB GPUs.
Why it matters
A compact open-weights editor/generator that runs on consumer GPUs undercuts closed leaders and challenges Qwen-Image 2.1 and Krea 2.
Importance: 3/5
notable release (major version, significant open-weights drop, or regulatory shift)
