BFL releases FLUX 3 Image Klein: 5.6B open weights, native 4K on one consumer GPU
Gradio · x · 2026-10-16
Black Forest Labs announced FLUX 3 Image Klein: open weights, 5.6B parameters, runs on a single consumer GPU, with native 4K output, bounding-box control, and pixel-perfect editing.
A side-by-side comparison by erhannah using the same crayon-mouse prompt and seed shows the new model's much stronger prompt adherence — FLUX.2 Klein (4B) produced a faceless hamster-like creature, while FLUX 3 Klein nails every detail: gray-brown mouse, upright pose, waxy crayon texture on cream paper.
