# Model Introduction

This image generation model, based on Laxhar/noobai-XL_v1.0, leverages full Danbooru and e621 datasets with native tags and natural language captioning.

Implemented as a v-prediction model (distinct from eps-prediction), it requires specific parameter configurations - detailed in following sections.

Special thanks to my teammate euge for the coding work, and we're grateful for the technical support from many helpful community members.

# ⚠️ IMPORTANT NOTICE ⚠️

## **THIS MODEL WORKS DIFFERENT FROM EPS MODELS!**

## **PLEASE READ THE GUIDE CAREFULLY!**

## Model Details

- **Developed by**: [Laxhar Lab](https://huggingface.co/Laxhar)
- **Model Type**: Diffusion-based text-to-image generative model
- **Fine-tuned from**: Laxhar/noobai-XL_v1.0
- **Sponsored by from**: [Lanyun Cloud](https://cloud.lanyun.net)

# How to Use the Model.

## Method I: [reForge](https://github.com/Panchovix/stable-diffusion-webui-reForge/tree/dev_upstream)

1. Install reForge by following the instructions in the repository;
2. Switch to `dev_upstream_experimental` branch by running `git checkout dev_upstream_experimental`;
3. Launch reForge WebUI;
4. Find "_Advanced Model Sampling for Forge_" accordion at the bottom of the "_txt2img_" tab;
5. Enable "_Enable Advanced Model Sampling_";
6. Select "_v_prediction_" in the "_Discrete Sampling Type_" checkbox group.
7. Generate images!

## Method II: [ComfyUI](https://github.com/comfyanonymous/ComfyUI)

TODO

## Method III: [WebUI](https://github.com/AUTOMATIC1111/stable-diffusion-webui)

Note that dev branch is not stable and **may contain bugs**.

1. (If you haven't installed WebUI) Clone the repository:

```bash
git clone https://github.com/AUTOMATIC1111/stable-diffusion-webui
```

2. Switch to `dev` branch:

```bash
git switch dev
```

3. Pull latest updates:

```bash
git pull
```

## Method IV: [Diffusers](https://huggingface.co/docs/diffusers/en/index)

```python
import torch
from diffusers import StableDiffusionXLPipeline
from diffusers import EulerDiscreteScheduler

ckpt_path = "/path/to/model.safetensors"
pipe = StableDiffusionXLPipeline.from_single_file(
    ckpt_path,
    use_safetensors=True,
    torch_dtype=torch.float16,
)
scheduler_args = {"prediction_type": "v_prediction", "rescale_betas_zero_snr": True}
pipe.scheduler = EulerDiscreteScheduler.from_config(pipe.scheduler.config, **scheduler_args)
pipe.enable_xformers_memory_efficient_attention()
pipe = pipe.to("cuda")

prompt = """masterpiece, best quality,artist:john_kafka,artist:nixeu,artist:quasarcake, chromatic aberration, film grain, horror \(theme\), limited palette, x-shaped pupils, high contrast, color contrast, cold colors, arlecchino \(genshin impact\), black theme,  gritty, graphite \(medium\)"""
negative_prompt = "nsfw, worst quality, old, early, low quality, lowres, signature, username, logo, bad hands, mutated hands, mammal, anthro, furry, ambiguous form, feral, semi-anthro"

image = pipe(
    prompt=prompt,
    negative_prompt=negative_prompt,
    width=832,
    height=1216,
    num_inference_steps=28,
    guidance_scale=5,
    generator=torch.Generator().manual_seed(42),
).images[0]

image.save("output.png")
```

4. Launch WebUI and use the model as usual.

**Note**: Please make sure Git is installed and environment is properly configured on your machine.

# Usage Guidelines

## Caption

```
<1girl/1boy/1other/...>, <character>, <series>, <artists>, <special tags>, <general tags>, <other tags>
```

## Quality Tags

For quality tags, we evaluated image popularity through the following process:

- Data normalization based on various sources and ratings.
- Application of time-based decay coefficients according to date recency.
- Ranking of images within the entire dataset based on this processing.

Our ultimate goal is to ensure that quality tags effectively track user preferences in recent years.

| Percentile Range | Quality Tags   |
| :--------------- | :------------- |
| > 95th           | masterpiece    |
| > 85th, <= 95th  | best quality   |
| > 60th, <= 85th  | good quality   |
| > 30th, <= 60th  | normal quality |
| <= 30th          | worst quality  |

## Date Tags

There are two types of date tags: **year tags** and **period tags**. For year tags, use `year xxxx` format, i.e., `year 2021`. For period tags, please refer to the following table:

| Year Range | Period tag |
| :--------- | :--------- |
| 2005-2010  | old        |
| 2011-2014  | early      |
| 2014-2017  | mid        |
| 2018-2020  | recent     |
| 2021-2024  | newest     |
