Pixel Alchemy V13 It's a merge of 4 checkpoints and 3 LORAs (see list below). One of the main goals is was to obtain a very versatile checkpoint. It's NSFW one.
Quite efficient in rendering landscapes, realistic portraits, surrealism and gives better results with noise reinjection in ComfyUI (see below, the recommended extension)
