DNA 1.0 8B Instruct

DNA 1.0 8B Instruct is a state-of-the-art (SOTA) bilingual language model based on Llama architecture, specifically optimized for Korean language understanding and generation, while also maintaining strong English capabilities. The model was developed through a sophisticated process involving model merging via spherical linear interpolation (SLERP) with Llama 3.1 8B Instruct, and underwent knowledge distillation (KD) using Llama 3.1 405B as the teacher model. It was extensively trained through continual pre-training (CPT) with a high-quality Korean dataset. The training pipeline was completed with supervised fine-tuning (SFT) and direct preference optimization (DPO) to align with human preferences and enhance instruction-following abilities.

DNA 1.0 8B Instruct was fine-tuned on approximately 7B tokens of carefully curated data and has undergone extensive instruction tuning to enhance its ability to follow complex instructions and engage in natural conversations.

Evaluation Protocol
For easy reproduction of our evaluation results, we list the evaluation tools and settings used below:

Quickstart

This model requires transformers >= 4.43.0.

from transformers import AutoModelForCausalLM, AutoTokenizer, TextStreamer

tokenizer = AutoTokenizer.from_pretrained('dnotitia/Llama-DNA-1.0-8B-Instruct')
model = AutoModelForCausalLM.from_pretrained('dnotitia/Llama-DNA-1.0-8B-Instruct', device_map='auto')
streamer = TextStreamer(tokenizer, skip_prompt=True, skip_special_tokens=True)

conversation = [
    {"role": "system", "content": "You are a helpful assistant, Dnotitia DNA."},
    {"role": "user", "content": "너의 이름은?"},
]
inputs = tokenizer.apply_chat_template(conversation,
                                       add_generation_prompt=True,
                                       return_dict=True,
                                       return_tensors="pt").to(model.device)
_ = model.generate(**inputs, streamer=streamer)

Limitations

While DNA 1.0 8B Instruct demonstrates strong performance, users should be aware of the following limitations:

• The model may occasionally generate biased or inappropriate content
• Responses are based on training data and may not reflect current information
• The model may sometimes produce factually incorrect or inconsistent answers
• Performance may vary depending on the complexity and domain of the task
• Generated content should be reviewed for accuracy and appropriateness
