Krea2 TextFusion Refusal-Reduction [by Capitan01R]

indeed. @CraigToomy we gotta never take things for granted and must all stay greedy and download and hoard everything. who knows if civit . red will remain intact long term.

No, it's technical, but the bottom line is the higher versions "go deeper" in the model substructure, so they provide a deeper coverage at the price of more skew to the gen output.

The thing is, with Krea2 that skew to the gen isn't necessarily a bad thing, 'cause the innate NSFW refusal is so strong it actually skews gen output by default, which is why base Kerea2 actually has worse prompt adherence than when u add a refusal reduction /any NSFW lora to it.

So... it's complicated.

And each gen is different, no way to give a hard rule which to use.

But still, If you have no clue, I'd advise use v1, or v2 is also good, but if you see your particular prompt/lora combo needs more NSFW unlock then you'll need to go with the deeper fix.

@ravemry9 deeper fix means the v2 full rank, right?

@ralphjx yeah, v2 full-rank is deepest, then goes v2, and v1 is lightest.

@ralphjx I've just heard from @oneluckyluke that v2 (non full-rank) has an artifact problem

Yep, In order of usefulness: V2 full rank, V1, then V2. For it's size, V1 gets me about 95% of all the unlocks I need so it's hard to justify using the full rank version given its size.

Also, you should know that the base krea 2 model only has so much knowledge of NSFW concepts, you can't unlock what the model doesn't know. Finding a good finetune (e.g Kroma ODP) that has a huge amount of NSFW knowledge baked in should be the place to start.

Lastly, this helps with more than just NSFW, it also helps with prompt adherence to facial expressions, actions and even art styles. For example, krea2 turbo struggles showing people sneezing or spitting or furious, this lora enables the model to do that. There is a wide range of things that the model interprets as "unsafe" for no good reason and it will refuse to portray it or simply dampen its effect.

@oneluckyluke thx.
BTW, you mention Krea2 turbo so I just wanna add that I've had the same prompt adherence struggles (including facial expressions) with full Krea2.
P.S. I love the Krealism and Gonzolamo fine-tunes, you have any idea if they have the added NSFW range on par with KromaODP?

@ravemry9 I haven't tried those fine tunes yet but I will check them out soon! Thanks for putting me onto them

@oneluckyluke So, is this LoRA—in its v1 or v2 full-rank version—better than the "bypasslora" that’s also available here on Civitai?

@ralphjx In my limited experimentation, I think so. I started out using the bypass lora and switched to this one because I was getting better results with it.

@oneluckyluke @ralphjx

same here. I did a bunch of tests with several NSFW-unlock loras before deciding this is the best. (but some of them weren't poorer quality, just heavier style bias or similar subjective preferences. I do think capitan01r's is the most comprehensive unlock with the least side effects; objectively).

@ravemry9 I tried version v1, and the difference in terms of adherence was night and day compared to BypassLora. I’m definitely sticking with this one. Thanks, guys, for the response.

V1, hands down. other 2 must be overtrained or something because for me they give boring results.

Yes, it helps, but it's usually not necessary, their use-cases overlap.

It's a matter of personal taste, but imo mystic has more of style and composition bias and this lora is more of a pure NSFW-unlock.

In my experiments, mystic works great for NSFW concepts that the base model doesn't have. This lora helps with prompt adherence for things that are damped by the base model's safety filters like facial expressions, open/closed mouths and other non-NSFW poses. Mystic tampers with art styles since it's mostly trained on realistic content.

Best combination I've found for NSFW is using kroma-ODP and this refusal lora. Kroma gives you more NSFW concepts than mysticxxx and incredible prompt adherence including styles.

@oneluckyluke This is very useful info, thx.

I hadn't realized the krea problem with facial expressions would be fixed by NSFW unlocks! stupid of me, should've realized. Thanks a lot. I've been fighting with krea for a long time to get grumpy cats, almost never works, do you know if animal expressions are in the same boat?

Also, I'm into bondage (light; just basic ropework) and base krea is pretty bad at it, do you know if mystic is better at it?

@ravemry9 Yes, animal expressions are definitely in the same boat, I tested this with krea2 turbo and refusal v1. Tried to generate angry 3d monkeys. Without the refusal Lora, best I could get is "mildly annoyed", the safety filters soften the expressions to make them non-threatening. Once I added the refusal lora, the monkeys are way more furious and menacing, bearing fangs and claws, angry skin folds on the face etc. The difference is night and day.

I have no idea if mystic is any good at bondage, I dropped it as soon as I tested Kroma-ODP as my base model for NSFW. It is trained on a much wider range of NSFW concepts. There's also "Sick ollie" and "Lustify" that might work for your use case.

@oneluckyluke got it, all the info is much appreciated XOXO

@oneluckyluke May I join your discussion? I have a question: I recently discovered the Crea2 Turbo model and this LoRA. I wanted to ask—if I use them to generate anime-style NSFW content, what might happen? I also noticed a mention of "kroma-ODP"—what is that? Thanks!

@Sputnik_Art I'm not sure what you mean by "what might happen", I'm assuming you are asking about the quality of the generated image? If so, it depends on a lot of things, Krea 2 turbo generally produces decent anime quality images with only prompt descriptions. The model contains a "safety lock" that will steer away from NSFW images. If you use this LoRA combined with Krea 2 turbo and a good anime prompt or anime LoRA, you will get an NSFW anime image. This LoRA will remove the "safety lock" so the Krea 2 Turbo model can generate NSFW.


"Kroma ODP" is a model based on Krea that has been trained on more NSFW and anime images so it "knows" about a lot of different NSFW and anime concepts. Krea 2 turbo may understand human anatomy well and some basic sexual concepts but Kroma understands more advanced and complex sexual concepts. However, because it was trained in such a way that it preserves a lot of the original Krea's capabilities, it sometimes suffers from the same "safety lock" issue so you may need to unlock it (not always though). Kroma also produces more variety for the same prompt and it understands prompts a lot better than Krea 2 turbo. I have noticed for example that it understands style prompts much better.

Hope this helps.

@oneluckyluke Understood, thank you for the response. I used a translator, as English is not my native language. Thank you.

I don't know, but announcement on his profile said a few days ago that his reddit account was banned or something like that.

@RisingV damn.

Hope the peanut gallery didn't drive him away, he made good work and seemed a good guy -- afaict this is the best krea2 unlock (for pure nsfw unlock, the others like mystic are great but have so much style/concept bias)
