FLUX 3 Image Klein MLX Q4

Unofficial affine 4-bit / group-64 derivative. Complete package includes Q4 DiT and Qwen3-VL text weights, FP32 VAE, tokenizer and original license/notices. Native Swift/MLX inference: zimageapp/zimage, Flux3CLI --model /path/to/package --prompt "a red apple" --output out.png.

Default: 1024 square, 16 distilled flow-map steps, no CFG. --fp16-dense selects attention projections; --cache-di-t enables approximate fixed-interval prediction reuse. Both are opt-in.
