AnimeBoysXL v1.0

It takes substantial time and efforts to bake models. If you appreciate my models, I would be grateful if you could support me on Ko-fi ☕.

Features

✔️ Good for inference: AnimeBoysXL v1.0 is a flexible model which is good at generating images of anime boys and males-only content in a wide range of styles.
✔️ Good for training: AnimeBoysXL v1.0 is suitable for further training, thanks to its neutral style and ability to recognize a great deal of concepts. Feel free to train your own anime boy model/LoRA from AnimeBoysXL.
❌ AnimeBoysXL v1.0 is not optimized for creating anime girls. Please consider using other models for that purpose.

Inference Guide

Prompt: Use tag-based prompts to describe your subject.
- Append , best quality, amazing quality, best aesthetic, absurdres to the prompt to improve image quality.
- (Optional) Append , year YYYY to the prompt to shift the output toward the prevalent style of that year. YYYY is a 4 digit year, e.g. , year 2023
Negative prompt: Choose from one of the following two presets.
1. Heavy (recommended): lowres, (bad:1.05), text, error, missing, extra, fewer, cropped, jpeg artifacts, worst quality, bad quality, watermark, bad aesthetic, unfinished, chromatic aberration, scan, scan artifacts, 1girl, breasts
2. Light: lowres, jpeg artifacts, worst quality, watermark, blurry, bad aesthetic, 1girl, breasts
- (Optional) Add , realistic, lips, nose to the negative prompt if you need a flat anime-like style face.
VAE: Make sure you're using SDXL VAE.
Sampling method, sampling steps and CFG scale: I find (Euler a, 28, 5) good. You are encouraged to experiment with other settings.
Width and height: 832*1216 for portrait, 1024*1024 for square, and 1216*832 for landscape.

🧨Diffusers Example Usage

python

import torch
from diffusers import DiffusionPipeline

pipe = DiffusionPipeline.from_pretrained("Koolchh/AnimeBoysXL-v1.0", torch_dtype=torch.float16, use_safetensors=True, variant="fp16")
pipe.to("cuda")

prompt = "1boy, solo, male focus, hoodie, grey hoodie, hood, hood up, close-up, sleepy, short hair, bara, undercut, stubble, black hair, green eyes, parted lips, white background, simple background, best quality, amazing quality, best aesthetic, absurdres, year 2023"
negative_prompt = "lowres, (bad:1.05), text, error, missing, extra, fewer, cropped, jpeg artifacts, worst quality, bad quality, watermark, bad aesthetic, unfinished, chromatic aberration, scan, scan artifacts, 1girl, breasts"

image = pipe(
    prompt=prompt, 
    negative_prompt=negative_prompt, 
    width=1024,
    height=1024,
    guidance_scale=5,
    num_inference_steps=28
).images[0]
