| **Dataset:** 4xRealWebPhoto_v4 |
| **Dataset Size:** 8492 |
| **OTF (on the fly augmentations):** No |

| |
| **Description:** The first real-world drct model, so I am releasing it, or at least my try at it, maybe others will be able to get better results than me, I think I'd recommend my [4xRealWebPhoto_v3_atd](https://github.com/Phhofm/models/releases/tag/4xRealWebPhoto_v3_atd) model over this one if a real-world model for upscaling photos downloaded from the web is desired. |
| This model is based on my previously released drct pretrain. Used mixup, cutmix, resizemix augmentations, and mssim, perceptual, gan, dists, ldl, focalfrequency, gradvar, color and luma losses. |
