This model is actually by https://civitai.com/user/Ikena
It's up on huggingface https://huggingface.co/iZELX1/Grapefruit with an Openrail ML license.
Author has put up some of his other "fruits" line, like Yuzu.
Nice model so thought it belonged here as well.
This one tends to have softer lines.

Does tend towards NSFW, but as you can see, does very nice SFW as well.

Rendering tips:

• Tends to like 30 steps

• Likes some samplers more than others. Sample images are rendered with StableSwarmUI, using Euler, and DPM++ 2m SDE GPU. It likes gpu version over non.

• Goes well with EasyNegative embedding

Generally, the more details you give it, the better results you will get.
