      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:

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

Fine-Tuning on Predibase

This model was fine-tuned using Predibase, 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. Try out our free Predibase trial here.

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, the open-source toolkit for LLMs that Predibase is built on.

Co-trained by: Infernaught

How To Use The Model

To use these weights:

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")
