### 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              |
|----------------------------|-----------|-----------|--------------------|-----------------|----------------------|-------------------|
| Fluxmania Legacy (25 step) | BF16      | --        | 175.08             | 0.895           | --                   | --                |
