## Model Details

**Model Developers** Kyujin Han (kyujinpy)

**Input** Models input text only.

**Output** Models generate text only.

**Model Architecture** 

CoT-llama2 is an auto-regressive language model based on the LLaMA2 transformer architecture.

**Base Model**
[Llama-2-ko-7b](https://huggingface.co/beomi/llama-2-ko-7b)

**Training Dataset**

I use [KoCoT_2000](https://huggingface.co/datasets/kyujinpy/KoCoT_2000).  
Using DeepL, translate about [kaist-CoT](https://huggingface.co/datasets/kaist-ai/CoT-Collection).

I use A100 GPU 40GB and COLAB, when trianing.

**Training Hyperparameters**

| batch_size | `64` |   
| micro_batch_size | `1` |
