I was dinking around with dynamic prompts for Stable Diffusion again, and at one point ended up getting a robotic catgirl. This seemed like a fine idea, so I stripped it down to the basics and tried to build back up into a specific look. I was getting reasonably consistent results with one model, but it was weak on backgrounds. TL/DR, I ended up running the same prompt and seed through 64 models because I wasn’t able to get all the elements at the same time: clearly robotic body, metal skin and face, metal cat ears and tail, pretty face, sexy figure, naughty bits covered, interesting background, requested pose.
So I ran the exact same prompt and seed through 64 models:
4k, crisp, high budget, highly detailed, intricate, ultra textured.
photorealistic, hyper realistic, ((robot girl)) at ((Towering spires
of glass piercing a sea of swirling mist)). ((robot face)), ((silver
metal skin)), ((silver metal face)), ((metal hair)), tiny breasts,
silver metal cat tail, black metal cat ears, full body, teen height,
teen face, teen body, wearing ((black metal corset bodysuit)), ((black
metal stockings)), ((black metal long gloves)), ((black metal collar))
with ((glowing crystal bell)). Cross-legged on floor, hands on knees,
upright posture, calm and collected with a cheerful expression.
I tried to bias it toward a slender look with “teen face/body/height” and “tiny breasts” (which generally produces B-C instead of D-H). I moved the location to the beginning because I kept getting just floors and solid-color backgrounds with the occasional generic room interior. Repeating the colors for each item helps to keep them from bleeding into other elements, but, as usual, doesn’t always work.
Definitely a catgirl, mostly-correct costuming, matte silver skin except for neck and eyes, plausibly robotic arms and legs, terrible tail (fur, broken), robot cat-ears, cute face, sleek little body, appealing pose but doesn’t match the prompt, nice background that matches prompt.
Very robotic cat-faced catgirl, WTF tail, cool-looking but WTF hair, sexy body, only used two costume elements, appealing pose but doesn’t match the prompt, completely generic background.
Catgirl but the tail grows out of her hand, head seems to have been imported from a completely different art style, nice work on the costume (except the feet), great background, nothing screams “robot”.
Definitely a robot catgirl, with metal hair and liquid-metal tail, decent costuming, cute face but shame about the lack of facial expression, sleek little body, some elements of the requested pose, generic background.
Definitely a robot catgirl, glowing bell, liquid-metal tail, excellent costume match, sexy body but definitely not “tiny breasts”, generic background, shame the face just isn’t very pretty.
Girl wearing cat-ears, nothing robotic about her except the bored-fashion-model expression, bell is just stuck to her skin rather than attached to the collar, dull face, sexy body, excellent costume except for the WTF vajazzling, mostly-correct pose, excellent background.
Prettier than the last one, but otherwise pretty much the same description applies. I kinda wonder where her lower legs are, though.
Wow, this one took the “teen” part seriously, the “tiny breasts” are actually tiny for once, not a catgirl but cute with a nice smile, I think there’s a messed-up bell in the collar somewhere, good costume, good pose, cool background, but WTF on that cat-ear headpiece.
(this is actually one of the best results I’ve gotten from bigASP for any prompt…)
I’d say this is more of a cyborg catgirl because of the human ears and skin tones that overrode the prompt in places, glowing crystal bell, segmented metal tail, pose that has nothing to do with the prompt and is more “power” than “sexy”, good costume, generic background.
(Bolero is one of my favorites for anime-style art, but I usually get much better backgrounds from it)
Another cyborg catgirl due to the skin tones, pity about the furry tail, good costume, cute-but-blank face, sleek little teen body, nice pose that ignored the prompt, generic room background.
(another favorite for anime-style, also usually delivers better backgrounds)
Organic catgirl in space armor, very cute, little smile, sleek teen body, almost-correct pose, some costume elements, generic background. Can I keep her?
Setting aside the furry tail, I think this robot catgirl was sent back from the future to kill Sarah Connor. Otherwise, nice costume, terrific background, pose completely ignores prompt.
This blank-faced Fetish Queen Of Venus has a great costume and a terrific background, but nothing cat-girly about her.
Her cousin (yes, the models are related) at least seems to have had cybernetic cat-ear implants, but her take on the costume looks more like armor. Prettier, but will probably shoot you on sight.
This one wins the Cutest Teen Cosplayer award, no tail, tacked-on ears, nothing robotic about her, good pose, excellent costume, cool background.
Armored Sorceress Queen staring blankly out over her domain, cool costume, pose ignores prompt, great background.
Not a single cat or robot element, pose ignores prompt, gorgeous gal with sexy body, great costume, great background, could use a more lively expression.
Sci-fi catgirl rather than robot, good pose, decent costume, pretty-but-blank face, nice body, generic background.
I’m declaring this one a cyborg catgirl rather than a robot because I want all that exposed skin to be warm and lickable, even though I’m pretty sure she’s the assassin-bot type. Good costume, usual random appealing pose, great background.
Erotic cosplayer, good pose, good costume, excellent background.
To no surprise, a furry model made a cat-faced catgirl, but it also made her a proper robot, got the costume right, gave her a glowing bell, and made an excellent background. Not sure what’s going on in back, with what looks like a stubby metal tail and an ass-mounted thruster. Cute and shapely, though I’d like to see a better pose.
Definitely a robot catgirl, good costume, tail doesn’t seem to be attached and apparently has a rabbit’s foot at the end, nice body, something a bit off in the face, background is not generic but ignores prompt.
Apart from the furry tail, this is an excellent robot catgirl, pretty face, nice smile, nice body, good costume, good match for the requested pose, generic background.
Newbie Cosplayer who’s a little freaked out by the way fan photographers drool and try to peek down her top.
Mostly flesh-and-blood catgirl who specializes in discipline, applied with her cybernetic left hand. Great costume, pretty gal, sexy body, nice background.
Sci-fi catgirl in skintight spacesuit, pretty face, sleek body, generic pose, generic background.
Cyborg catgirl, no tail, pretty face with barely enough expression, sexy body, good costume, pose pretty close to prompt, excellent background, probably hangs out with the queen and her cousin from earlier.
Pretty sure you can buy that entire outfit at the Hustler store, especially the buttplug-tail. Nice body, decent background.
Pretty little cyborg catgirl, shame her lower legs were crushed. Nice outfit, decent pose, excellent background.
Apart from a hint of fur at the tip of the tail, this checks almost all the boxes except the background.
Erotic cosplay with vajazzling and crushed lower legs. Nice costume, nice background, probably the best rendition of “tiny breasts” yet. Suspiciously similar to Lustify output, making me suspect they’ve got a common parent.
Definitely a robot catgirl, face a little too robo to be cute, sleek little body, kinky metal tail, excellent costume, pose made goofy by attempting to follow the part of the prompt that said “hands on knees” and nothing else, generic background.
Sexy cosplayer with cat-ear headphones, excellent costume, excellent pose, pretty gal, sexy body, simple-but-not-generic background.
Now that’s a sexy robot catgirl! Could use a little more expression, and a background, but she rocks the pose and the costume.
The face looks like it was pasted on a picture of a robot. Pretty much ruins it for me.
Oh, another one of those gals. Nothing new here, likely another related model.
…and another. I’d rank this one the sexiest of the lot, though.
Cool and hot, but since it has nothing to do with the prompt, I have no idea how I’d ever invoke this look again. I’m willing to try, though.
A lot of models build off of this one, but it’s not the origin of this much-seen look and feel. See below…
Sci-fi gal dressed as a catgirl; I’m sure the ears and tail are programmed to move. Cute, sweet teen body, excellent costume, excellent pose, excellent background.
Very similar to Nova Unreal; I think I prefer that one.
Obviously related to DynaVision, but this one at least gave her the ears. All the same comments apply.
Surprisingly faithful to the prompt, but as a plastic chibi instead of metal. Very cute, but an actual figurine of her would result in serious questions from visitors.
Solid effort across the board. Yummy.
The Cosplayer Who Tried Way Too Hard. Love the crotch bell.
Oh, FFS, another one?
Sigh.
Everything is descended from this, so this is where they all ultimately come from. Everything that’s not like this comes from the additional training data people other than Stability AI put into SDXL.
I’d say this one’s halfway between the base model and Princess Aura in the 1980 Flash Gordon film, in a good way. Sadly, not a robot catgirl, though.
Next!
This is more interesting than the other SDVN models, and also is the Queen Of Robot Catgirls.
We’ve seen this before, but at least this one’s not vajazzled.
A breath of fresh air, even if she’s more cyber-ogress-babe than catgirl. This is clearly a combat model, and the cleavage window in her armor is designed to distract enemies before she mercilessly slaughters them. Another non-catgirl to try to reproduce another time.
Next!
Next!
More stylish than the others of this type, although the gal looks like someone punched her awake.
Very faithful to the prompt, and suspiciously similar to Mistoon.
Speaking of suspiciously similar, Pornworks, Nova Hentai, and CyberRealistic Pony all did basically the same pic as this. I’d rank this one second, since the CRP gal was the cutest.
Third appearance for this gal, only this time she’s seated and has what looks like a sex toy on the end of her tail.
No crystal background this time, but otherwise a familiar picture. She’s cute enough to tie for second, or maybe edge out the WAI ANI NSFW Pony gal.
Let’s just back away slowly and pretend we never entered the room. Nice body, though.
Yep, another one.
Looks like this one had just enough training material to nudge her away from the overused template. I’m guessing a lot of K-Pop girls are in the mix.
I’m seeing a lot of DynaVision in this one, or maybe ProtoVision since it has cat-ears and enough artificial elements to qualify her for cyborg catgirl status. Excuse me, that’s smoking hot cyborg catgirl.
Well, I do have 9 Flux models, but I can’t use the exact same parameters. I had to take CFG down to 1, Steps to 35, Scheduler to DEIS, and Sampler to Simple. Flux Guidance was set to 2.
All of the Flux results look quite similar:
Nope.
Not a robot, not a cyborg, just a shiny forehead and some stick-on cat ears. Other than that, it followed the prompt pretty well.
Pretty much matches the prompt, except the face has a freakish uncanny-valley look to it.
Excellent match for the prompt, without an ounce of cuteness. I like the clawed robot arms, but the whole scene is kind of grim and industrial.
Even the base model does a good job with this, so any praise for the others comes from the additional training they supply.
I like the texturing on the face and body, but we lost the tail.
Unlike some earlier ones that mixed in human skin tones, this works, mostly because she’s really pretty with a nice smile and tasty cleavage. The cat-ears look cosmetic and literally bolted on, but again, hot catgirl.
Titties! Cosplayer with bad paint job on the face, otherwise usual good prompt adherence.
More titties! Prettier cosplayer without even a hint of robo.
