The different variations are trained on different POVs
(a) Seated POV
Fairly flexible. Tags should include at least: "1girl, 1boy, oral, fellatio". Weight for most of these versions is optimal around 0.8. If you want a version of this with paizuri check out this model.
(b) Straddling / Guy on Top POV
Really wants to generate paizuri with an oral fixation. Not a bad thing, but not what it says on the tin. It's still definitely possible to generate fellatio with choice prompting. See the sample images. Can also help to mix in some of A or C (if you see Q or Z this is what that means). Looking for more data.
(c) Standing POV
Turned out pretty similar to A. Better than A at generating kneeling partner / higher perspective especially with tags like "kneeling, from above". Looking for more data.
(d) Lying / Under Sheets POV
Work in progress. Not quite there yet.
(q/z) Experimental
Blends of the above 4. May publish some if any turn out to be particularly good at anything
There is a lot of potential for experimentation and I'm not the person to do that. If you want all the files (dataset, outputs w/ diferrent epochs, samples, merges), download them from this magnet URL:
