# Qwen1.5-MoE-2x72B

## Description
This model is created using MoE (Mixture of Experts) through mergekit based on [Qwen/Qwen1.5-72B-Chat](https://huggingface.co/Qwen/Qwen1.5-72B-Chat) and [abacusai/Liberated-Qwen1.5-72B](https://huggingface.co/abacusai/Liberated-Qwen1.5-72B) without further FT.

It utilizes a customized script for MoE via mergekit, which is available [here](https://github.com/Aratako/mergekit-qwen2).

Due to the structural modifications introduced by MoE, the use of this model requires [custom modeling file](https://huggingface.co/Aratako/Liberated-Qwen1.5-2x72B/blob/main/modeling_qwen2.py) and [custom configuration file](https://huggingface.co/Aratako/Liberated-Qwen1.5-2x72B/blob/main/configuration_qwen2.py).
When using the model, please place these files in the same folder as the model.

This model inherits the the [tongyi-qianwen license](https://huggingface.co/Qwen/Qwen1.5-72B-Chat/blob/main/LICENSE).
