Model Architecture
COKAL-DPO_13b-v2 is an auto-regressive 13B language model based on the LLaMA2 transformer architecture.

Base Model DopeorNope/COKAL_pre_DPO_Test_v2-13b

DopeorNope/COKAL_pre_DPO_Test_v2-13b is the SFT model to train with DPO methodology.

Training Dataset

• DPO training dataset: DopeorNope/DPO-Ko-Dataset - private

This dataset was constructed by directly collecting and reorganizing data by DopeorNope, obtaining insights from "lvwerra/stack-exchange-paired" to create a paired dataset. (It means I do not use stack-exchange-paired; I just got an insight from it.)

• SFT training dataset: DopeorNope/Orca_Near_Dedup-v2 - private

This dataset is based on "kyujinpy/OpenOrca-KO" and has been processed using the Near Dedup algorithm to remove items with a Jaccard Similarity threshold of 0.8 or higher. In addition, inconsistent inputs have been cleaned and modified.

Training
The difference between "DopeorNope/COKAL-DPO_test-v2" and this model is that this model has different hyper-parameters from the one in that setting regarding the final version.

I developed the model in an environment with four RTX 3090 GPUs running Ubuntu 18.04.

It seems that when uploading the model directly to a repository from a Linux server, there may be an issue causing the model to appear to have more parameters. However, this model is based on a 13B architecture.
