Made from the perfect blend of three NSFW models, Trifecta XL is capable of producing a much wider range of realistic NSFW images than any of its constituent parts. It scored higher on my prompt test than any other SDXL model and showed a very high level of understanding of positioning, posing, and the most common sexual acts. Trifecta was created from the painstaking evaluation of multiple rounds of merging and analysis of the individual u-net blocks from all three models until the perfect weight ratio and merge method was achieved.

The Trifecta model was created to be the base of a new generation of mixes, but it seems to work just fine on its own. However, its creativity is somewhat limited, and it tends to oversexualize everything. Which I guess is the point if you are going to use it straight up to generate images.

A note on watermarks: Yep, it's got them. However, they appear less often, are smaller, and are often positioned off the image. I managed to "push" many off or nearly off the generated image. Check below for usage tips for more information on how to limit them.

Usage Tips:

This is a replacement for using Pyro’s XL model as the base of some of my own future merges. It was optimized to produce ****. It doesn’t know many art styles, and it has a very narrow understanding of the world outside of ****. If you use it for something else, you are doing it wrong.
Noting the above, Trifecta does make an excellent base model to train LoRAs and use in your own NSFW merges. It has a very good understanding of anatomical structures, including hands and feet. Having training data that is a bunch of naked people doing all kinds of stuff with their hands and bodies will do that. And if you do use Trifecta to make or make a LoRA, let me know, and I’ll link to it.
Trifecta XL is capable of generating a wide range of soft and ******** images, but its conceptional understanding is also pretty vanilla – and that’s intentional. If you want something to cater to your darkest and most perverse desires, you’ll have to find a LoRA for it. Again, if you find or make LoRAs that work well, let me know, and I’ll link them to them.
The model knows what a penis is. It understands all the things that can be done with a penis. It does not always understand that a penis needs to be connected to a man. Perhaps the model is being progressive in its understanding of gender fluidity and that disembodied penises sometimes just float around giving and receiving pleasure. AI’s can be weird. If it happens, try another seed and make sure your prompt includes a male participant.
Keep your prompts simple when prompting NSFW images. The model gets confused easily if it thinks elements of the prompt conflict with each other, particularly when it comes to framing and points of view.
This model has much less of a watermark issue than other NSFW models – as long as you don’t mention it. Funny story: I tested this model out with 50 NSFW prompts to measure its abilities and comprehension. Out of 50 hard-core images, less than 1 in 5 were watermarked. Then I started generating images for the showcase, and EVERY image had a watermark. The only difference? I didn’t use a negative prompt or any quality keywords in my test. My showcase images all used “high resolution, best quality, 4k” in the positive prompt and a bunch of watermark terms and keywords in the negative prompt.

Prompting:

Natural language works best. Describe your subjects and what they are doing. As noted above, if you don't want watermarks, avoid using quality keywords in the positive prompt and mentioning watermark-type things (websites, logos, etc.) in the negative prompt. You'll still get some, but most are tiny or almost pushed off the image.

This model is not intended and does not tend to produce illegal acts and images. However, to be 100% safe, add "children, loli, child, kids, teens" to your negative prompt. The model understands "girl" = "woman," but it's safer to use the latter.

Because it's a merge of several models and LoRAs and was optimized for certain acts, most keywords, phrases, and concepts from any of the merged models still work. The examples below can be used but don’t need to be used in their entirety; a few of the phrases or keywords below out of the list usually work.

a woman titty fucking, penis, sex, titty ****
