This is a finetune on top of my Impish_Nemo_12B, the goal was to improve long context understanding, as well as adding support for slavic languages. For more details look at Impish_Nemo_12B's model card.

So is this model "better"?

Hard to say, tuning on top of a model often changes it in unpredictable ways, and I really like Impish_Nemo. In short, this tune might dillute some of the style that made it great, or for some, this might be a huge improvement, to each their own, as they say, so just use the one you have most fun with.

TL;DR

• Theoretically better long context.
• Improved Russian and other slavic languages.
• New settings for better longer context for this model here. You can download the yaml here.

Regarding the format:

It is HIGHLY RECOMMENDED to use the Roleplay \ Adventure format the model was trained on, see the examples below for syntax. It allows for a very fast and easy writing of character cards with minimal amount of tokens. It's a modification of an old-skool CAI style format I call SICAtxt (Simple, Inexpensive Character Attributes plain-text):
