      Below is an instruction that describes a task, paired with an input that
      provides further context. Write a response that appropriately completes
      the request.

      ### Instruction: Generate an SQL statement to add a row in the customers table where the columns are name, address, and city.

      ### Input: name = John, address = 123 Main Street, city = Winter Park

      ### Response:
inference:
  parameters:
    temperature: 0.1

## QLoRA weights using Llama-2-7b for the Code Alpaca Dataset

This model was fine-tuned using [Predibase](https://predibase.com/), the first low-code AI platform for engineers.
I fine-tuned base Llama-2-7b using LoRA with 4 bit quantization on a single T4 GPU, which cost approximately $3 to train
on Predibase.

Dataset and training parameters are borrowed from: https://github.com/sahil280114/codealpaca,
but all of these parameters including DeepSpeed can be directly used with [Ludwig](https://ludwig.ai/latest/), the open-source
toolkit for LLMs that Predibase is built on.

To use these weights:
```python
from peft import PeftModel, PeftConfig
from transformers import AutoModelForCausalLM

config = PeftConfig.from_pretrained("arnavgrg/codealpaca-qlora")
model = AutoModelForCausalLM.from_pretrained("meta-llama/Llama-2-7b-hf")
model = PeftModel.from_pretrained(model, "arnavgrg/codealpaca-qlora")
```
