Pal #139, Nyafia

The bad catgirl. Sample pictures are all cherry-picked raw gens to demonstrate the model's capabilities in pure text2image. No inpainting or upscaling was done.

Prompting

Weight: 0.9 (maximum flexibility and expressiveness) to 1.0 (fewer reminder tags needed)

Trigger words: nyafia, semi-anthro and nyafia, anthro

The full nya: nyafia, semi-anthro, ambiguous gender, purple fur, pink hair, yellow eyes, hair over one eye, black dress, long sleeves, :3

Reminder Tags

In harder art styles, or more complex situations, the model might forget certain stuff. I've compiled a list of the tags you can use to improve your feline.

• purple fur, pink hair, yellow eyes, hair over one eye - It usually remembers this stuff, but if it starts making things that aren't nyafia at all, adding these will probably make it generate one again.

• :3 - Nyafia have resting smug face.

• black dress, long sleeves, pink fur trim - In particular, it forgets the sleeves pretty often. It can be tough to get the dress just right.

• flat chest - One way to convince it to not give them breasts. Also experiment with featureless chest and/or putting breasts in the negatives.

• no nose / noseless - If the style insists on giving them one.

• striped tail - It has trouble with the tail, but this helps a lot.

• 3 fingers, white claws - Hands are hard, what else is new with AI? This can help some.

• black feet - Only use if you actually want the feet in the frame, but if it's making them purple, this'll put the sock markings back on. You could also use socks \(marking\) to be more specific, but I haven't needed to.

Quality Indicators

Obviously, these are just my subjective ratings. But this is my experience so far.

★★★☆☆ Character Likeness

It can do the character, but in a lot of situations, it needs a whole pile of extra tags as reminders of what it's making. It fails the tail way more often than I would like. Overall, usable but could be better.

★★★★★ Flexibility

Side and back views work fine, and the back view mostly remembers to do the tail. Expressions are very expressive! Doesn't fight me on poses or costumes. It can even draw them upside-down! Although that mixes up which eye the hair is over more often than normal. (Of course it's still supposed to be over the eye, it's obviously glued there!)

★★★★★ Style Compatibility

Leaves most styles untouched. Some of the more unusual ones, like lineless art or really chibi stuff, gets a little lost.

★★★★★ Other Checkpoints

I haven't noticed anything specific that goes wrong when using other checkpoints. Realism comes out great in models like RealMondAI-SDG.

★★★★☆ Other Characters

When using regional prompting, nyafia-specific traits don't tend to leak into non-nyafia regions, even when they have a lot of similar attributes (pink hair, purple fur, black dress, and so on). Mixes traits badly if not using regional prompting, though.

★★★★★ Sanity

Has a bias toward adding dirt paths, bushes, and mountains. It's not hard to override. Anatomy remains pretty good. It occasionally decides the eyes should be glowing, not really sure why. Probably haunted.

Training Info

Base model: NoobAI-XL EPS 1.0

Concept data: 9 human-created images and 1 render of the in-game model (1/10 porn, 6/10 with breasts)

Regularization data: 100 AI-generated images from the base model, same captions as the concept data, without "nyafia", with randomized aspect ratios and quality tags

Balance: 1 regularization image per 1 concept image, same loss weight

Total Steps: 5000

Notes: You'd think 5000 steps would be enough to make it pretty reliable, but nope. Still, I've gotten it to do everything I've wanted it to do with a few retries and a lot of reminder tags.

Things Nobody Asked (Yet)

Another nyafia LoRA?

Yeah, there are already two Illustrious-based models for these critters, but this one is mine and I like it. I have no other excuse.

Can it make porn?

Asking the important questions! Yes, you can plap the cat.

Why do they have extra ears?

A lot of pals seem to have something like that. In the nyafia's case, the three sets of pseudo-ears are for radio communication: the big ones are AM/FM receivers, and the two sets below are for SiriusXM and 5G.
