Lora Training (arcain_2411.safetensors)

Lora trained on Illustrious-xl v0.1, but this lora can applied with other ILXL-based models such as NoobAI-XL.

• Tool: kohya-ss/sd-scripts
• GPUs: 4x RTX3060
• Dataset: pls2000/aiart_channel_nai3_geachu + additional data until 24/11/14 - blue archive data
• Time taken: 50.5 hours (walltime)
