ying11231 · x · 2026-10-17
BFL releases FLUX 3 Image Klein, a 5.6B open-weights image model claiming frontier-level quality that runs on a single consumer GPU, with native 4K output, bounding-box control, and pixel-perfect editing.
The community project Miles-Diffusion already supports RL training on FLUX 3 Klein Base: the whole pipeline runs on a single node, with both LoRA and full-parameter RL validated end to end, plus a cookbook.
