## Model

### [hardcore-hentai-v12](https://modelslab.com/models/modelslab/hardcore-hentai-v12)

**Model ID:** hardcore-hentai-v12
**Category:** Stable Diffusion
**Type:** Sd1.5
**Provider:** Modelslab

https://civitai.com/models/136054?modelVersionId=232266

[This model is using BAKED VAE]

Prompt
best quality,

I like to keep the filler tags to a minimum, but you can get good result with more tags too.

Use danbooru tags or sentence-based prompts

Extension for tag autocompletion&nbsp;tagcomplete

Prompt Order for good composition
Tags at the start have more influence than the ones at the bottom.

The 7 blocks template&nbsp;(Work in progress):



view angle,



participants -&gt;1girl,&nbsp;1boy,&nbsp;sex acts,&nbsp;sexual positions,



posture, secondary actions,



body -&gt;&nbsp;breasts size, body fat, age, stature,&nbsp;body part focus,



hair color,&nbsp;hair style,&nbsp;eyes,&nbsp;face expressions,&nbsp;cum location,



clothing,



location, furniture, objects,



You don't need to fill in every category, it's just for reference.

Negative prompt
worst quality, low quality, normal quality,

And whatever you don&rsquo;t want to be on the image

Some people use the standard (worst quality, low quality: 1.4) + negative embeddings with good results too.

Samplers
I like&nbsp;DPM++ SDE Karras&nbsp;but you can use any sampler. Some samplers converge at a defined image, others keep changing with each step.

You can find better explanations&nbsp;here&nbsp;and&nbsp;here.

Steps
25+

CFG


7: standard



3&ndash;15:&nbsp;working range



Lower cfgs don&rsquo;t follow the prompt as much. Higher cfgs will make &ldquo;burned&rdquo; images

The extension&nbsp;sd-dynamic-thresholding&nbsp;can play around with different CFGs at different steps

Sizes


1:1&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; [512, 512], [768, 768]



2:3&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; [512, 768]



3:2&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; [768, 512]



You can use Hires fix to get a bigger picture with more details

Tags: nsfw, anime
