# `rinna/youri-7b`

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

# Overview
We conduct continual pre-training of [llama2-7b](https://huggingface.co/meta-llama/Llama-2-7b-hf) on **40B** tokens from a mixture of Japanese and English datasets. The continual pre-training significantly improves the model's performance on Japanese tasks.

The name `youri` comes from the Japanese word [`妖狸/ようり/Youri`](https://ja.wikipedia.org/wiki/%E5%8C%96%E3%81%91%E7%8B%B8), which is a kind of Japanese mythical creature ([`妖怪/ようかい/Youkai`](https://ja.wikipedia.org/wiki/%E5%A6%96%E6%80%AA)).

* **Library**
    
    The model was trained using code based on [EleutherAI/gpt-neox](https://github.com/EleutherAI/gpt-neox).

* **Model architecture**

    A 32-layer, 4096-hidden-size transformer-based language model. Refer to the [llama2 paper](https://arxiv.org/abs/2307.09288) for architecture details.

* **Continual pre-training**

    The model was initialized with the [llama2-7b](https://huggingface.co/meta-llama/Llama-2-7b-hf) model and continually trained on around **40B** tokens from a mixture of the following corpora
    - [Japanese CC-100](http://data.statmt.org/cc-100/ja.txt.xz)
    - [Japanese C4](https://huggingface.co/datasets/mc4)
    - [Japanese OSCAR](https://huggingface.co/datasets/oscar-corpus/colossal-oscar-1.0)
    - [The Pile](https://huggingface.co/datasets/EleutherAI/pile)
    - [Wikipedia](https://dumps.wikimedia.org/other/cirrussearch)
    - rinna curated Japanese dataset

# How to use the model
