## Try out this model on [VESSL Hub](https://vessl.ai/hub).

This example fine-tunes [Llama 2](https://ai.meta.com/llama/) on a code instruction dataset. The code instruction dataset is consisted of 1.6K samples and follows the format of Stanford's [Alpaca dataset](https://github.com/gururise/AlpacaDataCleaned). 
To optimize the training process into a single GPU with moderate memory, the model uses [8 bit quantization](https://huggingface.co/blog/hf-bitsandbytes-integration) and LoRA (Low-Rank Adaptation).

In the code we are referencing under `/code/`, we added our Python SDK for logging key metrics like loss and learning rate. You can check these values in real-time under Plots. The run completes by uploading the model checkpoint to VESSL AI model registry, as defined under `export`.

## Running the model

You can run the model with our quick command.
```sh
vessl run create -f llama2_fine-tuning.yaml
```

Here's a rundown of the `llama2_fine-tuning.yaml` file.
