+This is a Gemma-2 2B Finetune with surprisingly good Role-Play capabilities for its small 2B size. 
+
+  **Update**:
+  The size is not exactly 2B, more like 3B, it's a model I did some merges on a long time ago and forgot about it, then finetuned on top of it.
+
+  Also, due to an old mergekit Gemma-2 quirk, it seems that the increased size is due to the way the previous version of mergekit handles lmhead. Anyway, it turned out pretty awesome, even for a 3B size. The base is presented in FP32.
