I could say something cute like "special sauce" but I'll just list the ingredients:

This is PonyRealism gently cross-mixed with JuggernautXL until I could get better photorealism and IPAdapter response while maintaining minimal knowledge loss.

Some LoRAs have been baked in to skew results more body/age positive, another form of added realism. One unexpected result of the blending in of Juggernaut, there is also a greater ethnic diversity in the results. You may find this model less "horny" than other Ponys, if desired it can be brought back by adding "nsfw" to the prompt.

Steps 25-40 (as low as 16 with attention tricks like PAG)

CFG 4-8

This one shines with a Latent Upscale type workflow where the resulting image is upscaled ~1.6x and denoised again at about 0.33.
