YARN: Yet Another Realistic NSFW

This is yet another realistic NSFW lora, hence the name. It applies a photograpic realistic look and kinda does it all : AI influencers, everyday fully clothed pictures, erotic pictures, sex scenes, different body types and skin tones.

v1.0:

Yarn v1.0 is here!

This version is based on Qwen 2512, and was trained during 110k steps on a huge dataset. After extensive tests, I'm quite confident this is amongst the best realistic NSFW Lora on Civitai.

Although it was almost exclusively trained on SFW and NSFW of woman-focused photographs, as well as B/G interaction, this Lora is very good at plain SFW realistic image generation.

This iteration is by far the most stable and can be composed with other Loras such as character Loras. All tests were performed using the nunchaku version of Qwen 2512, with the 8 steps Lightning Lora.

v0.3:

This is an intermediate training step of YARN based on Qwen 2512. It performs amazingly well, and is still improving with further training. Pictures often have a distinct "studio look", which I like. I'm even finding myself using the Lora for purely SFW generations.

Pros:

• Very good at photorealism

• Male and female anatomy are very good

• Diverse faces and body types

• Composition coherence is improved

• Retains high quality when stacked with a character Lora

Cons:

• Still issues differentiation between the two holes. This is a captionning issue (I used JoyCaption), which will not improve with further training

• Nude men are often missing the shaft if not specifically prompted

v0.2:

I changed the training settings and ran ~x5 training steps. This results in great improvements: v0.2 is much more stable, gives good results at strengths 0.5-1.5 and above. The artifacts present in v0.1 have disappeared. Overall, in my very biased opinion, this is a serious contender for best NSFW Qwen Lora on Civitai.

v0.1:

The lora is a tad too strong at the moment, works best at lora strengths 0.3-0.8.

Known issues : It knows the downstairs anatomy quite well, but can't really differentiate between the two holes in prompts.
