# Model Card for Model ID

This PEFT weight is for predicting BTC price.

Disclaimer: This model is for a time series problem on LLM performance, and it's not for investment advice; any prediction results are not a basis for investment reference.

## Model Details

Training data source: BTC/USD provided by [Binance](https://www.binance.com/).

### Model Description

This repo contains QLoRA format model files for [Meta's Llama 3 8B tw Instruct](https://huggingface.co/DavidLanz/Llama3-tw-8B-Instruct).
