The long awaited followup to ICBINP, this model is merged to try and get the most realistic images possible. Version 3 now has that same realistic skin, but more details in the image, that more popular look (due to the merging with the DPO lora), and less reliance on the hi-res fix.
It's the ICBINP you all know and love, but now with all of the benefits of SDXL (recommended 832x1216)
The sample images are all made with the DPM++ 2M Karras, 30 steps, 832x1216, cfg 3, clip skip 1, and basic hi-res fix with 4x-Upscaler, and occassionally adetailer with the default settings (A1111). I liked the results I got with the Restart sampler as well, so that is recommended. I'm sure that some more experimentation and better workflows you will be able to achieve amazing results!
