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 ☕.



  • ✔️ Good for inference: AnimeBoysXL 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 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 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.

    • 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

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

    • 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

    • 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: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.

Training Details

AnimeBoysXL is trained from Stable Diffusion XL Base 1.0, on ~516k images.

The following tags are attached to the training data to make it easier to steer toward either more aesthetic or more flexible results.

Quality tags

  • best quality: score >= 150

  • amazing quality: score in the range of [100, 150)

  • great quality: score in the range of [75, 100)

  • normal quality: score in the range of [0, 75)

  • bad quality: score in the range of (-5, 0)

  • worst quality: score <= -5

Aesthetic tags

  • best aesthetic: score >= 6.675

  • great aesthetic: score in the range of [6.0, 6.675)

  • normal aesthetic: score in the range of [5.0, 6.0)

  • bad aesthetic: score < 5.0

Rating tags

  • sfw: general

  • slightly nsfw: sensitive

  • fairly nsfw: questionable

  • very nsfw: explicit

Year tags

year YYYY where YYYY is in the range of [2005, 2023].

Training configurations

  • Hardware: 4 * Nvidia A100 80GB GPUs

  • Optimizer: AdaFactor

  • Gradient accumulation steps: 8

  • Batch size: 4 * 8 * 4 = 128

  • Learning rates:

    • 8e-6 for U-Net

    • 5.2e-6 for text encoder 1 (CLIP ViT-L)

    • 4.8e-6 for text encoder 2 (OpenCLIP ViT-bigG)

Changes from v1.0

  • Train with tag ordering.

  • Add sfw rating tag.

  • More epochs on the questionable and explicit rating subset.

  • FP16 mixed-precision training for final epochs.
