A fine-tuning experiment revealed that a costly $50,000 run using H100 GPUs resulted in a model that "forgot more" than a significantly cheaper $1,500 run. The author explored three fine-tuning methods: full fine-tuning, LoRA, and QLoRA, on the same 8B model. The findings suggest that the expense of fine-tuning does not necessarily correlate with better performance or knowledge retention. AI
IMPACT Suggests that expensive fine-tuning does not guarantee better model performance or knowledge retention.
