dt-flux2-klein-4b

FLUX.2 [klein] 4B weights in the Draw Things (s4nnc .ckpt) format, mirrored unmodified from the Draw Things model CDN for use by JoyFusion's on-device inference. The conversion and quantization were done by the Draw Things project; the files here are byte-identical to the upstream ones.

File	Variant	Size	SHA-256
flux_2_klein_4b_q6p.ckpt	6-bit	3,117,088,768	ba42005a6d4e6c48430787db98ae8913aced4654682b59d0d0f1d9ccf820fe30

The shared components live in JoyFusionAI/dt-components:
