Wiedervereinigung-7b-dpo

This is a dpo aligned merge of multiple german models scoring 7.1 on the mt-bench-de average. It is a merge of the best german 7B models with 7b parameters as a dare_ties merge. Since the original models based on mistral - three of them on the brilliant german LeoLM/leo-mistral-hessianai-7b - they are reunited in this merged model. Therefore the name, no nationalist ideas involved. To improve result quality they are dpo-trained with a german translation of intel-orca-dpo using our german fork of LLaMA-Factory.

mt-bench-de

Is the merged model good? Well, of course. But it is even better with the help of some dpo tuning.
