Magnolia-v2-12B

Magnolia-v2-12B

This is a merge of pre-trained language models created using mergekit.

This model essentially a rebuild of v1, using task arithmetic instead of SLERP. Of note, Mistral Nemo Base was used as the base model for task arithmetic, rather than Instruct or another fine-tune. Furthermore, max_position_embeddings was reduced to 131072, down from 1000000, as the model was only trained on up to 131072. Tested with temperature 1.0 and minP 0.01; temperature can be reduced (briefly tested at 0.45) if the model is too aggressively creative/hallucinatory.
