Animagine XL 2.0
## Overview
**Animagine XL 2.0** is an advanced latent text-to-image diffusion model designed to create high-resolution, detailed anime images. It's fine-tuned from Stable Diffusion XL 1.0 using a high-quality anime-style image dataset. This model, an upgrade from Animagine XL 1.0, excels in capturing the diverse and distinct styles of anime art, offering improved image quality and aesthetics.
## Model Details
- **Developed by:** [Linaqruf](https://github.com/Linaqruf)
- **Model type:** Diffusion-based text-to-image generative model
- **Model Description:** This is a model that excels in creating detailed and high-quality anime images from text descriptions. It's fine-tuned to understand and interpret a wide range of descriptive prompts, turning them into stunning visual art.
- **License:** [CreativeML Open RAIL++-M License](https://huggingface.co/stabilityai/stable-diffusion-2/blob/main/LICENSE-MODEL)
- **Finetuned from model:** [Stable Diffusion XL 1.0](https://huggingface.co/stabilityai/stable-diffusion-xl-base-1.0)
## LoRA Collection
The Animagine XL 2.0 model is complemented by an impressive suite of LoRA (Low-Rank Adaptation) adapters, each designed to imbue the generated images with unique stylistic attributes. This collection of adapters allows users to customize the aesthetic of their creations to match specific art styles, ranging from the vivid and bright Pastel Style to the intricate and ornate Anime Nouveau.
## Gradio & Colab Integration
Animagine XL is accessible via [Gradio](https://github.com/gradio-app/gradio) Web UI and Google Colab, offering user-friendly interfaces for image generation:

## 🧨 Diffusers Installation
Ensure the installation of the latest `diffusers` library, along with other essential packages:
```bash
pip install diffusers --upgrade
pip install transformers accelerate safetensors
```
The following Python script demonstrates how to do inference with Animagine XL 2.0. The default scheduler in the model config is EulerAncestralDiscreteScheduler, but it can be explicitly defined for clarity.
```py
import torch
from diffusers import (
StableDiffusionXLPipeline,
EulerAncestralDiscreteScheduler,
AutoencoderKL
)
# Load VAE component
vae = AutoencoderKL.from_pretrained(
"madebyollin/sdxl-vae-fp16-fix",
torch_dtype=torch.float16
)
# Configure the pipeline
pipe = StableDiffusionXLPipeline.from_pretrained(
"Linaqruf/animagine-xl-2.0",
vae=vae,
torch_dtype=torch.float16,
use_safetensors=True,
variant="fp16"
)
pipe.scheduler = EulerAncestralDiscreteScheduler.from_config(pipe.scheduler.config)
pipe.to('cuda')
# Define prompts and generate image
prompt = "face focus, cute, masterpiece, best quality, 1girl, green hair, sweater, looking at viewer, upper body, beanie, outdoors, night, turtleneck"
negative_prompt = "lowres, bad anatomy, bad hands, text, error, missing fingers, extra digit, fewer digits, cropped, worst quality, low quality, normal quality, jpeg artifacts, signature, watermark, username, blurry"
image = pipe(
prompt,
negative_prompt=negative_prompt,
width=1024,
height=1024,
guidance_scale=12,
num_inference_steps=50
).images[0]
```
## Usage Guidelines
### Prompt Guidelines
Animagine XL 2.0 responds effectively to natural language descriptions for image generation. For example:
```
A girl with mesmerizing blue eyes looks at the viewer. Her long, white hair is adorned with blue butterfly hair ornaments.
```
However, to achieve optimal results, it's recommended to use Danbooru-style tagging in your prompts, as the model is trained with images labeled using these tags. For instance:
```
1girl, green hair, sweater, looking at viewer, upper body, beanie, outdoors, night, turtleneck
```
This model incorporates quality and rating modifiers during dataset processing, influencing image generation based on specified criteria:
### Quality Modifiers
| Quality Modifier | Score Criterion |
| ---------------- | --------------- |
| masterpiece | >150 |
| best quality | 100-150 |
| high quality | 75-100 |
| medium quality | 25-75 |
| normal quality | 0-25 |
| low quality | -5-0 |
| worst quality | <-5 |
### Rating Modifiers
| Rating Modifier | Rating Criterion |
| --------------- | ---------------- |
| - | general |
| - | sensitive |
| nsfw | questionable |
| nsfw | explicit |
To guide the model towards generating high-aesthetic images, use negative prompts like:
```
lowres, bad anatomy, bad hands, text, error, missing fingers, extra digit, fewer digits, cropped, worst quality, low quality, normal quality, jpeg artifacts, signature, watermark, username, blurry
```
For higher quality outcomes, prepend prompts with:
```
masterpiece, best quality
```

## Model Comparison (Animagine XL 1.0 vs Animagine XL 2.0)
### Image Comparison
In the second iteration (Animagine XL 2.0), we have addressed the 'broken neck' issue prevalent in poses like "looking back" and "from behind". Now, characters are consistently "looking at viewer" by default, enhancing the naturalism and accuracy of the generated images.
