Just Another Checkpoint aims at generating realistic pictures focused on humans (male and female) and excels at generating NSFW images. It is also good for landscapes.

Adetailer is not required but will greatly improve the results, I recommend its use.

This model is not enforced at all and sucks hard for the following concepts: animals, buildings, every concept the base model struggles with, anime and everything not realistic.

V2f

This version produces less realistic pictures but with greatly improved eyes, hands and NSFW scenes composition.

While not mandatory using both positive and negative prompts described below are advised (see prompts of showcase pictures above).

Prompting:

JAC supports natural verbose prompting, WD14 and the Pony template.

Recommended positive prompt:

As this model uses Pony as a base it reacts to the Pony aesthetic score:

score_9, score_8_up, score_7_up,

Realistic aspect can be enforced with additional prompt such as "source_photo, (realistic), detailed".

Recommended negative prompt:

draft, cropped, out of frame, cut off, censored, JPEG artifacts, out of focus, glitch, duplicate, 
(text,letters,ideograms,username, twitter username,copyright,patreon, patreon username, web address,watermark, signature, text font, username, error, logo, words, letters, digits, autograph, trademark, name:1.2),
long neck, long torso,bad hands, ugly, 
(censorship, censored, worst quality, low quality, normal quality, lowres, low details, bad photo, bad photography, bad art), (bad hands:1.4)

My usual go-tp negative prompt used for nearly all image generations.

Realistic aspect can be enforced with additional negative prompt such as "source_pony, source_anime, source_furry, source_cartoon".

V1f

V1 tries to generate pictures without specific or complicated prompting.

All the pictures on the showcase above are generated without negative prompt at all, no specific positive prompt and without Adetailer.

Prompting:

JAC supports natural verbose prompting, WD14 and the Pony template.

Positive prompt:

Just your prompt

Negative prompt:

bad hands

License and technical aspect:

This model use SDXL and Pony as a base and therefore inherits their Fair AI Public License 1.0-SD license. Please note that Pony license disallows the commercial use of their model and derivatives.

JAC model is for the most part a base Pony with injections of custom LoRAs made with high resolution photos (who were also used to create the Realism Enhancer LoRA). Details can be read in the checkpoint metadata.
