Description

I am fine-tuning on vicuna with a chat dataset and found that its performance on MMLU drops after fine-tuning.
As a practice, I wanted to check if y'all fine-tune vicuna on sharegpt till the loss becomes zero?
Ex. when vicuna-1.1 or 1.3 was trained on sharegpt data, was the training stopped when the loss became zero?
