It appears that the Illustrious base model contains a limited amount of Chibi data. It is recommended to lower the CFG (below 5) when using it, set the LoRa weight to 1.0, and remove quality descriptors such as "best quality" from the positive prompt.
似乎Illustrious底模中Chibi数据较少，建议使用时调低CFG（5以下）、将LoRa权重设置在1.0并删去正面Prompt中的“best quality”等质量描述词。
