Description:
A dat2 4x upscaling model, similiar to the [4xNomos2_hq_mosr](https://github.com/Phhofm/models/releases/tag/4xNomos2_hq_mosr) model, trained and for usage on non-degraded input to give good quality output.
I scored 7 validation outputs of each of the 21 checkpoints (10k-210k) of this model training with 68 metrics.
[The metric scores can be found in this google sheet](https://docs.google.com/spreadsheets/d/1NL-by7WvZyDMHj5XN8UeDALVSSwH70IKvwV65ATWqrA/edit?usp=sharing).
The corresponding image files for this scoring can be [found here](https://drive.google.com/file/d/1ZTp9fBMeawftNqzg4RN9_zIvHtul5jVc/view?usp=sharing)
Screenshot of the google sheet:

Release checkpoint has been selected by looking at the scores, manually inspecting, and then getting responses on discord which chose B to this quick visual test, A B or C, which denote different checkpoints: https://slow.pics/c/8Akzj6rR
Checkpoint B is 140k which is 4xNomos2_hq_dat2. But I added checkpoint A (4xNomos2_hq_dat2_150000) and checkpoint C (4xNomos2_hq_dat2_10000) model files additionally here if people want to try them out).
