## Model Details

danube-ko-1.8b-base is a continual pre-trained Korean language model based on [h2oai/h2o-danube2-1.8b-base](https://huggingface.co/h2oai/h2o-danube2-1.8b-base).

## Model Developers

Jinhong Jeong, Ungsang Yoon

## Model Architecture

The vocabulary size was expanded from original 32000 to 40000 to add Korean tokens efficiently. We used the [EEVE](https://arxiv.org/abs/2402.14714) technique for training. The model has sequence length of 2048. Everything else is the same as the original model.

## Training Datasets

We used CulturaX, Common Crawl CC-MAIN-2024-10, AI Hub Data, Korean Wikis, Corpora from National Institute of the Korean Language, Standard Korean Dictionary, etc. About 42GB of data was used for training.

## Model Benchmark

This model is ranked #1 in Ko-MMLU on the [Open Ko-LLM Leaderboard](https://huggingface.co/spaces/upstage/open-ko-llm-leaderboard) among pretrained Korean models of size 2B or smaller as of July 5, 2024.
