unsloth/Meta-Llama-3.1-8B-bnb-4bit fine tuning after Continued Pretraining

(TREX-Lab at Seoul Cyber University)

Summary

• Base Model : unsloth/Meta-Llama-3.1-8B-bnb-4bit
• Dataset : wikimedia/wikipedia(Continued Pretraining), FreedomIntelligence/alpaca-gpt4-korean(FineTuning)
• This llama model was trained 2x faster with Unsloth and Huggingface's TRL library.
• Test whether fine tuning of a large language model is possible on A30 GPU*1 (successful)

• Developed by: [TREX-Lab at Seoul Cyber University]
• Language(s) (NLP): [Korean]
• Finetuned from model : [unsloth/Meta-Llama-3.1-8B-bnb-4bit]
