# `rinna/youri-7b-chat-gptq`

![rinna-icon](./rinna.png)

# Overview
`rinna/youri-7b-chat-gptq` is the quantized model for [`rinna/youri-7b-chat`](https://huggingface.co./rinna/youri-7b-chat) using AutoGPTQ. The quantized version is 4x smaller than the original model and thus requires less memory and provides faster inference.

* **Model architecture**
