The idea behind this model merge is to create a perfect mix capable of generating artistic photography: artful portraits and beautiful landscapes.
Both HotArt and HotArt2 as well as HotArt3 are great in their own way, try both with the same seed/sampler = then use the one according to your taste ;)
This rich Checkpoint/LORA mix series is an experiment that worked out very well ;)
For HotArt2 better hands - use both of the suggested resources (LORAs) at low ~0.333 level.
See below for more examples of generation capabilities ?
