<!-- Provide a longer summary of what this model is. -->

- **Developed by:** [TREX-Lab at Seoul Cyber University]
- **Language(s) (NLP):** [Korean]
- **Finetuned from model :** [MLP-KTLim/llama-3-Korean-Bllossom-8B]

## Fine Tuning Detail

- alpha value 16
- r value 64 (it seems a bit big...@@)
```
peft_config = LoraConfig(
    lora_alpha=16,
    lora_dropout=0.1,
    r=64,
    bias='none',
    task_type='CAUSAL_LM'
)
```

- Mixed precision : 4bit (bnb_4bit_use_double_quant)
```
bnb_config = BitsAndBytesConfig(
    load_in_4bit=True,
    bnb_4bit_use_double_quant=True,
    bnb_4bit_quant_type='nf4',
    bnb_4bit_compute_dtype='float16',
)
```

- Use SFT trainer (https://huggingface.co./docs/trl/sft_trainer)
```
trainer = SFTTrainer(
    model=peft_model,
    train_dataset=dataset,
    dataset_text_field='text',
    max_seq_length=min(tokenizer.model_max_length, 2048),
    tokenizer=tokenizer,
    packing=True,
    args=training_args
)
```
