This model is an instruction-tuned model of Llama2-70B with our own medical Q&A dataset.

## Method 
QLoRA

## Parameters
- batch_size = 512
- max_steps = 30000 (around 6.89 epochs)
- source_max_len = 512
- target_max_len = 512

## Training time
1617017 seconds on NVIDIA A100 x 4 (not fully used)


## Training procedure


The following `bitsandbytes` quantization config was used during training:
- quant_method: bitsandbytes
