FLUX.3 Image Klein trends on Hugging Face and enters Diffusers

FLUX.3 Image Klein is trending on Hugging Face and in Diffusers, while sources disagree on size, features, and license.

Black Forest Labs' FLUX.3 Image Klein, also listed as flux-3-image-klein and FLUX 3 Image Klein, ranked #29 on Hugging Face on 2026-10-13 with 3,241 downloads and 145 likes. A separate listing, flux-3-image-klein-comfy, ranked #30 on 2026-10-14 with 39 downloads and 164 likes. Both cards describe image-to-image weights, mark the license as other, and omit parameter counts and benchmarks. On 2026-10-15 Hugging Face announced Diffusers support without weights size, benchmarks, or license terms. The Decoder instead reports a 5.6-billion-parameter model for text-to-image generation, editing, and up to ten reference images, with native 4K, pixel-accurate editing, and bounding boxes; it says an INT8 build runs on 8 GB NVIDIA VRAM and produces an image in under nine seconds on an RTX 4070. Sources disagree on scope and licensing: The Decoder cites the FLUX Kommunity License, free commercial use below $5 million annual revenue, API pricing of $0.009 per 1,000 images, and internal Elo tests showing a 91-point gain over 9-billion-parameter FLUX.2 [klein] with 38 percent fewer parameters, above other open models, Ideogram V4.5, and FLUX.2 [pro].
