### Quality Evaluation
Below is the quality and similarity evaluated with 256 samples from MJHQ-30K dataset. (BF16 is the unqauntized model. INT W4A4 is INT4 and NVFP4 is FP4)
| Model | Precision | Method | FID | IR | LPIPS | PSNR |
|----------------------------|-----------|-----------|--------------------|-----------------|----------------------|-------------------|
| CenKreChro (25 Steps) | BF16 | -- | 135.52 | 0.842 | -- | -- |
| | INT W4A4 | SVDQ | 135.50 | 0.795 | 0.255 | 20.64 |
| | NVFP4 | SVDQ | 134.19 | 0.849 | 0.219 | 21.30 |
