Thanks for making this model!

Three Qs:

• I understand teknium/OpenHermes-2.5 was used to originally do SFT on Mistral to get the base SFT model. But what dataset was used for the DPO itself?
• I notice that teknium/OpenHermes-2.5 has "from" instead of "role" and "value" instead of "content"... so I suppose you swapped those when formatting the chat data for the DPO (and SFT) steps?
• How did you decide what hyperparams to use for the DPO?
