CBDMix is a mixed model of BRAv5 and chilled remix V2, ranging from 10% to 90%. Since both of them are released under the openrail license family, the same CreativeML Open RAIL-M license will be applied to these models as well.
My personal recommendations are 60%, 65%, or 70%, but it may differ depending on your preferences.
Models with higher percentages will give you a more Chill-like faces, while lower models a more BRA-like result.
Since your preferences may vary, the choice is up to you :)
Here are the comparisons, just in case.
