This is a review for both for the main model and for the inpainting one.

I've been using Grapefruit for quite a while now, and it's good. It's really easy to get breathtaking images - both nsfw and sfw, but only if you're generating a girl solo.

Generating a decent sex scene that uses a pose that's more complex than cowgirl is a tricky quest. Grapefruit tends to fuse bodies, put them into monstrous positions, penises often disappear even with the emphasis on promp, and generating a scene that involves more than two characters (i.e. one girl and two penises) without getting mutants is such a tedious activity that I ended up just photoshopping dicks to pictures and sending them through img2img. Embeddings and loras help a lot, but not always.

Inpainting models is pretty decent too, but definitely has it's flaws - i.e. it seems like inpainting (at least for 4.1) model doesn't recognize a lot of booru tags that the main model does. Yesterday I spent ~1.5 hours trying to inpaint cum, because the model barely understands what I want from it.

Another main inpainting flow is a fact that the model tends to pick up shadows from the surrounding and turn it into black splotches/stripes that wouldn't come off (because there's more shadow around), or even blacking the whole inpainting zone.

All in all, this is the best hentai model around, but sometimes working with it is nerve-wrecking.

No matter what, lots of love to the author, can't wait to see how the model will evolve further!

P.S. Unedited images just to show off possibilities.
