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 ☕.

AnimeBoysXL V3

Features

• ✔️ Good for inference: AnimeBoysXL v3.0 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 v3.0 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.

Inference Guide

• Prompt: Use tag-based prompts to describe your subject.

  • Tag ordering matters. It is highly recommended to structure your prompt with the following templates:

    • 1boy, male focus, character name, series name, anything else you'd like to describe, best quality, amazing quality, best aesthetic, absurdres

    • 2boys, male focus, multiple boys, character name(s), series name, anything else you'd like to describe, best quality, amazing quality, best aesthetic, absurdres

    • For more detailed documentation, you can visit my article on Ko-fi (available to supporters only).

• Negative prompt: Choose from one of the following two presets.

  1. Heavy (recommended): lowres, bad, text, error, missing, extra, fewer, cropped, jpeg artifacts, worst quality, bad quality, watermark, bad aesthetic, unfinished, chromatic aberration, scan, scan artifacts

  2. Light: lowres, jpeg artifacts, worst quality, watermark, blurry, bad aesthetic

• VAE: Make sure you're using SDXL VAE.

• Sampling method, sampling steps and CFG scale: I find (Euler a, 28, 8.5) 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.
