V1.3 or Vx.3 is more artistic and is trained on fuwafuwa mix as base model. It's to most accurate to the character's likeness.

V2 consists of updated tags, V2 & V2.1 are SD1.5 base model.

V1.4.1 base model is SD1.5 and V1.4 is nai. Both are more human / anime specific, but fail as a character Lora. V1.4.1 should be used as a cat girl lora.

V1 and V1.2 were earlier experiments trying to tune and experiment with Kohya, base model is Meinamix (my preferred model).

Tags / prompts I found work well for V1 models were,

Linechu (Trigger Word), a boy with blue hair and cat ears, holding a penguin plushie, wearing a black top, flat chest, slightly chubby,

Keep at strength 1.

Laying on the side is bad for ai prompts, as much as I would like it. various laying poses and non-standing generations always produce weird results. Makes sense if you look at art like olympia, or try drawing trapeze artists.
