`rinna/youri-7b`

Overview

We conduct continual pre-training of llama2-7b 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, which is a kind of Japanese mythical creature (妖怪/ようかい/Youkai).

Library

The model was trained using code based on EleutherAI/gpt-neox.
Model architecture

A 32-layer, 4096-hidden-size transformer-based language model. Refer to the llama2 paper for architecture details.
Continual pre-training

The model was initialized with the llama2-7b model and continually trained on around 40B tokens from a mixture of the following corpora
- Japanese CC-100
- Japanese C4
- Japanese OSCAR
- The Pile
- Wikipedia
- rinna curated Japanese dataset

How to use the model

import torch
from transformers import AutoTokenizer, AutoModelForCausalLM

tokenizer = AutoTokenizer.from_pretrained("rinna/youri-7b")
model = AutoModelForCausalLM.from_pretrained("rinna/youri-7b")

if torch.cuda.is_available():
    model = model.to("cuda")

text = "西田幾多郎は、"
token_ids = tokenizer.encode(text, add_special_tokens=False, return_tensors="pt")

with torch.no_grad():
    output_ids = model.generate(
        token_ids.to(model.device),
        max_new_tokens=200,
        min_new_tokens=200,
        do_sample=True,
        temperature=1.0,
        top_p=0.95,
        pad_token_id=tokenizer.pad_token_id,
        bos_token_id=tokenizer.bos_token_id,
        eos_token_id=tokenizer.eos_token_id
    )

output = tokenizer.decode(output_ids.tolist()[0])
print(output)

Tokenization

The model uses the original llama-2 tokenizer.
