2B-ad

Update

July, 2025. This model is one of the more capable small models trained "back then", I was curious to see how it would be received if the model card will be minimal, well, I can say I confirmed that model card matters 🙃

It's a legit very, very good model for the size, and I might eventually retrain it. Maybe.

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.
