Momo XL - Training Details (Oct 15, 2024)

Dataset

Momo XL was trained using a dataset of over 400,000+ images sourced from Danbooru.

Base Model

Momo XL was built on top of SDXL, incorporating knowledge from two finetuned models:

Formula:
SDXL_base + (Animagine 3.0 base - SDXL_base) * 1.0 + (Pony V6 - SDXL_base) * 0.5

For more details:

Training Process

Training was conducted on A100 80GB GPUs, totaling over 2000+ GPU hours. The training was divided into three stages:

Finetuning - First Stage: Trained on the entire dataset with a defined set of training configurations.
Finetuning - Second Stage: Also trained on the entire dataset with some variations in settings.
Adjustment Stage: Focused on aesthetic adjustments to improve the overall visual quality.

The final model, Momo XL, was released by merging the Text Encoder from the Finetuning Second Stage with the UNet from the Adjustment Stage.
