<hr/>

 same as "pure" HotArt4 but with added equally 4 most popular LoRas for enhancement of artfulness and details (Faetastic details, More Details, More Artful, ... and the "SPO") - as a result = different output artistic style and even more rich details on your generated images!

 About this version


 This version adds Step-aware Preference Optimization (SPO) LORA, [a novel post-training approach that independently evaluates and adjusts the denoising performance at each step, using a step-aware preference model and a step-wise resampler to ensure accurate step-aware supervision... blah, blah, blah = makes the output way artfully beautiful, a.k.a. - NICER !!!]


 P.S.: The SPO approach is better than Direct Preference Optimization (DPO) that has extended its success from aligning large language models (LLMs) to aligning text-to-image diffusion models with human preferences. Unlike most existing DPO methods, which assume that all diffusion steps share a consistent preference order with the final generated images, this assumption neglects step-specific denoising performance and that preference labels should be tailored to each step's contribution.


 The idea behind this model merge is to create a perfect mix capable of generating artistic photography: artful portraits and beautiful landscapes.


 This rich Model/LoRA mix series is an experiment that worked out very well ;)
