Erato
The muse of lyric erotic poetry
Use for making nude men with the correct privates, works most of the time. It is a versatile model and can do a variety of styles. It can produce SFW and NSFW images. It can make male private parts without the need of LoRA. Although men was the focus, the model is very versatile, and can yield great results with the right prompt. All images in the showcase are straight prompt generations without inpainting, some were upsized in img2img or HiRez fix. It has some RPG knowledge and can produce from close to photoreal to something that approaches anime if prompted correctly.
V4
Brought the model merge more toward photographic style. The settings outlined below for Version 3 still apply. It is better now at making a penis by simply putting the word naked or nude, but it doesn't always work. Hi-Rez fix might yield you better results.
V3
The previous version was not converting to Diffusers so I felt an obligation to fix it. Instead I had to remake it. As before this model produces body variety and ages, unlike Euterpe that produces muscle guys with huge privates.
You do not need heavy prompting to get decent results, for best results:
Use Sampling steps between 25 and 40
Use CFG between 6.5 and 9
Sampling method DPM++ 2M Karras works well, Euler works as well, but leads to blurry results when upsizing. Feel free to experiment
You may not need many negatives, the folowing are recommended:
JuggernautNegative-neg
BadDream
UnrealisticDream
ng_deepnegative_v1_75t
verybadimagenegative_v1.3
If prompting a nude male you will most likely get something close to proper privates anatomy without using the word "penis", If it's close enough, go to img2img and you will most likely get something realistic. Not using penis should allow you keep women from having one as well.
If prompting "penis" you will definitely get one, larger and sometimes unrealistic, so use with care.
V2
The model was fully re-build from scratch. It now produces better body variety even when using generic negatives. It is versatile and can be used for more than photography. Be warned that it will not produce female private parts appropriately, and you will most likely end up with a futanari if you don't use negatives to take the private parts off.
NOTE: Version 2 does not convert to Diffusers and I am unable to repair the checkpoint. Feel free to use it in Automatic1111 and ComfyUI, but it will not work in InvokeAI. If you merge V2 with another checkpoint, the same thing will happen with the result. I do not want to take it down because it produces some nice outputs.
My other mixes:
Terpsicore: Muse of dance and mother to the sirens
This model used to reside here, not it has its own listing. Click the name of the muse to see that version. Use it to make Furry characters and hairier men.
Euterpe: The muse of flutes and music
Euterpe is a male focused nsfw model, it will generate private parts or similar even when not prompted and tends to avoid clothing. Good for fit men and possibly futa.
Description
Rebuilt because V2 did not convert to diffusers. This one works on InvokeAI
Although results are different than V2, I think they are improved. Still generates a variety of body types and art styles.
If you would like to get realistic sized male private parts, do not mention them explicitly and you will often get something close, upsize in img2img to improve them. If you would like something larger or well defined from the get go, then mention it explicitly.

Emm,V3 doesn't work well at tag "realistic" or "photo" ,so sad.Put "realistic" tag on ,but still got a pic in 2.5D
Realistic may not be a good token, it implies it’s trying to be real, use photo and maybe add camera setting to the positive. Do add the Juggernaut negative embedding (https://civitai.com/models/81563) and UnrealisticDreams (https://civitai.com/models/72437?modelVersionId=77173), and maybe illustration, cartoon to the negatives.
@Muserato still doesn't work. I'll go back to V2,Thx any way.
What actually is the difference between the Erato & Eutepe models? Both seem like they're turning out similar output...
Euterpe was an unintentional offshoot while mixing. The Euterpe version likes them very muscular, and naked with larger penis and will tend to include one even without prompting, it is also a bit more painterly. Erato can give you more body variety, especially without negatives. Using EasyNegative will make them muscular again. Erato defaults to clothed usually, unless prompted.
Erato is supposed to be more realistic, but because of a bad mix, Erato V2 ended up not converting to Diffusers because of one of the checkpoints that was mixed in it, so it did not work in InvokeAI for one (works fine in Auto1111 and others). I tried to fix it and could not find a way, so I tried to rebuild it without the problem checkpoint mixed in, but i never got it back to the same photo like qualities of V2. If you’d like more realistic outputs I recommend V2, but keep in mind that it you mix it with something else it will inherit the diffusers issue.
@Muserato I can second this. This is exactly what I found. I found Euterpe to be great but tended to move away from the photo realism I could get more easily with Erato. I still use both.
