It was decided to implement the model based on NAI-XL, a crazy leap in quality compared to the latest LORA. Since the model is easy to fine-tune, it has improved detailing of the environment, eyes, improved anatomy, fingers, variety in clothing, and, importantly, reduced contrast, that is, if in version 3.0 the contrast was very high and it was difficult to use additional lora, it was necessary to use cfg scale 2.5, now cfg scale with the same contrast is about 4, which gives a reserve for using additional LORA.
When using Latent (nearest-exact) scaling, there are much fewer artifacts (sometimes they are absent altogether), which indicates a significant increase in quality and improvement of anatomy (when scaling, anatomy is much more often preserved within the correct limits)
